Let&#8217;s try to get this with an example. <\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nstr1= 'Cake,Eggs'\n# split the string at a colon\nprint(str1.split(':'))\n#will give output as\n# &#x5B;'Cake, Eggs'] aka the original string only\n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-with-maxsplit-argument\"><span class=\"ez-toc-section\" id=\"split_with_maxsplit_argument\"><\/span>split() with maxsplit argument<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>It will verify the number of splits you want. The return type will be 1 added to maxsplit.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nStr = 'This,is,a,blog'\n# if maxsplit is 1\nprint(Str.split(', ', 1))\n#output:  'This' , 'is,a,blog'\n\n# if maxsplit is 2\nprint(Str.split(', ', 2))\n#output:  'This', 'is' , 'a,blog'\n\n# if maxsplit is 0\nprint(Str.split(', ', 0))\n#output:  'This,is,a,blog'\n<\/pre><\/div>\n\n\n<p>To interpret this piece of code, one has to get the idea of maxsplit simply. In case the integer specified for maxsplit is 0, this implies 0 splits are needed. So we got the exact same string as Str i.e., 0+1=1 division of the entire string, Str. <\/p>\n\n\n\n<p>Similarly,  when one was passed as a maxsplit argument, it resulted in 1+1=2 divisions. Hence we got the desired output.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-with-a-character\"><span class=\"ez-toc-section\" id=\"Split_with_a_character\"><\/span>Split with a character<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>You can also pass a character as an argument. So, the Python split() function will separate the string into divisions when it encounters the first occurrence of the given character.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nStr = 'This,is,a,blog'\nprint(Str.split('h'))\n#output:  &#x5B;'T', 'is,is,a,blog'] \n\nStr = 'Thisisahorse'\nprint(Str.split(&quot;h&quot;))\n#output: &#x5B;'T', 'isisa', 'orse']\n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-file-content-using-splitlines\"><span class=\"ez-toc-section\" id=\"Split_file_content_using_splitlines\"><\/span>Split file content using splitlines()<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Once you have opened a file in read mode, you can split the words in the file using the splitlines() function.  It will display a list format of all words. Its syntax is: <\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nMy_file.splitlines())\n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-an-array-in-python\"><span class=\"ez-toc-section\" id=\"Split_an_array_in_Python\"><\/span>Split an array in Python<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>numpy.array_split() function is used for splitting the array into smaller divisions. The return type is an array only. This works under the numpy module only. Its parameters are array, indices, and axis. The third one is optional. Indices mean the number of subarrays you wish to obtain.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nimport numpy as np\nArr= np.array(&#x5B;1, 2, 3, 4])\nResult = np.array_split(Arr, 2)\nprint(Result)\n#output : &#x5B;array(1,2),array(3,4) ]\n<\/pre><\/div>\n\n\n<p>Hence, through this example, you can divide the array into two parts using the array_split function in Python.  The return type is list only. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-and-join-a-string\"><span class=\"ez-toc-section\" id=\"Split_and_join_a_string\"><\/span>Split and join a string<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>After splitting the string, you might want to join it using a delimiter. This is possible through the join() function. Assume that the split string is passed as an argument to the join function. Now, you just need to specify the delimiter.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\njoined_string = '-'.join(split_string)\n#syntax of join function \n#string after splitting is sent as an argument to this function \n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-with-several-delimiters\"><span class=\"ez-toc-section\" id=\"Split_with_several_delimiters\"><\/span>Split with several delimiters <span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There might be a possibility of several delimiters in your string. In this case, use <strong>re<\/strong> module of Python. Consider the following example:<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nimport re\nstringA = 'W, is\\n  character'\n#Here, delimeters are comma and new line character \nprint(re.split(&quot;,|\\n&quot;, stringA))\n#output : &#x5B;'W', 'is' , 'character']\n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-python-split-without-removing-the-delimiter\"><span class=\"ez-toc-section\" id=\"Python_split_without_removing_the_delimiter\"><\/span>Python split() without removing the delimiter<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Python has a split() function that will split a string into pieces based on the delimiter. This can be useful for splitting up files or other text that you want to parse, but it&#8217;s not always the best way to do it. If you have a piece of text that is already separated by some delimiter, like a comma or pipe symbol, then splitting the text with split() isn&#8217;t going to work. In this case, you should use join() instead.<\/p>\n\n\n\n<p>Now, if you want to split without removing the delimiter, then, first, usually split by specifying the delimiter and then, using list comprehension, add that delimiter to each iteration. Split methods are based on the pattern-separator (or <span style=\"text-decoration: underline;\"><strong><a href=\"http:\/\/www.pythonpool.com\/regex-new-line\/\" target=\"_blank\" rel=\"noreferrer noopener\">regex<\/a><\/strong><\/span>, if you prefer). The syntax for splitting a string is: <strong>str.split(pattern[, maxsplit])<\/strong><\/p>\n\n\n\n<p>Here the pattern is the <em>pattern to split against<\/em>, and maxsplit is the maximum number of splits allowed by the pattern; otherwise, it defaults to 1 (which means no limit). As an example, look at this,<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nstr1 = 'work,with,pythonpool'\ndelim= ','\nmy_list = &#x5B;x+delim for x in str1.split(delim) if x]\n#output will be:  &#x5B;'work,', 'with,', 'pythonpool,']\n<\/pre><\/div>\n\n<div class=\"monsterinsights-inline-popular-posts monsterinsights-inline-popular-posts-kilo monsterinsights-popular-posts-styled\" ><div class=\"monsterinsights-inline-popular-posts-text\"><span class=\"monsterinsights-inline-popular-posts-label\" >Popular now<\/span><span class=\"monsterinsights-inline-popular-posts-border\" ><\/span><span class=\"monsterinsights-inline-popular-posts-border-2\" ><\/span><div class=\"monsterinsights-inline-popular-posts-post\"><a class=\"monsterinsights-inline-popular-posts-title\"  href=\"https:\/\/www.pythonpool.com\/fixed-typeerror-cant-compare-datetime-datetime-to-datetime-date\/\">[Fixed] typeerror can&#8217;t compare datetime.datetime to datetime.date<\/a><\/div><\/div><\/div><p><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-python-split-vs-split\"><span class=\"ez-toc-section\" id=\"Python_split_vs_split%E2%80%98_%E2%80%98\"><\/span>Python split() vs split(&#8216; &#8216;)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In Python, you can use the split() function to create a list of elements from a string. You can also use the split(&#8216; &#8216;) function to create a list of elements from a string. The split() function is typically used when you have a single string to process and want to break it down into multiple parts, whereas the split(&#8216; &#8216;) function is typically used when you have multiple strings to process and want to break them down into multiple parts.<\/p>\n\n\n\n<p>The split() function takes two arguments: the separator character and the max number of elements in your result list. The separator character is what separates each element in your result list; it must be a single character (like &#8216;,&#8217; or &#8216;.&#8217;), not a regular expression or an exception that matches one of these characters.<\/p>\n\n\n\n<p>The max number of elements in your result list is something that specifies how many times each element should be repeated before another new element is added to the end of your result list.<\/p>\n\n\n\n<p>The split() function splits a string into multiple parts, while the split(&#8216; &#8216;) function splits the string into multiple parts and appends empty strings at the end of each part. Let&#8217;s take a look at an example:<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\ns = 'hello world' &gt;&gt;&gt; s.split ( ) &#x5B; 'hello', 'world' ]\n<\/pre><\/div>\n\n\n<p>Now let&#8217;s see how they perform on the same task:<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\ns2 = &quot;hello world&quot; &gt;&gt;&gt; s2.split ( ) &#x5B; 'ello', 'WORLD' ]\n<\/pre><\/div>\n\n\n<p>As you can see, they do pretty much the same thing. Now let&#8217;s look at another use case: if you want to split the text into words in Python. Using split(&#8216; &#8216;, 1) will return a list containing just the first word in your string and an empty list if there are no words left in your string after splitting it on whitespace or punctuation marks (commas, periods, etc.). Split(&#8216; &#8216;, 2) returns an array of two-element tuples containing only words separated by spaces or commas.*<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-in-python-dataframe\"><span class=\"ez-toc-section\" id=\"Split_in_Python_dataframe\"><\/span>Split in Python dataframe<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Assume that after importing pandas, you have a dataframe column on which you have to perform the split function. It has several arguments. In this case, pat refers to a pattern suggesting the delimiter.  True Value for expand means that you don&#8217;t need the answer in List format but in series format only.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\ndf&#x5B;'name'].str.split(pat = ' ', expand = True)\n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-email-address-in-python\"><span class=\"ez-toc-section\" id=\"Split_email_address_in_Python\"><\/span>Split email address in Python<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you want to extract the domain name from an email address, @ delimiter will be used.

It uses four parameters, namely pattern, string, maxsplit, and flags. The maxsplit value is mostly 0, and the same goes for the flag variable.

It splits using a delimiter, or you may provide a stream of characters. Also, you need to specify how many splits you want. This is referenced by the maxsplit operator.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\ntext = 'Python is one of the easiest languages to learn and it is extremely comprehensible.'\nprint(text.rsplit('is', 1))\n#splits from the first 'is' from right\n<\/pre><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-split-the-list-into-sublists-based-on-the-value\"><span class=\"ez-toc-section\" id=\"Split_the_list_into_sublists_based_on_the_value\"><\/span>Split the list into sublists based on the value<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The easiest way is to use <span style=\"text-decoration: underline;\"><strong><a href=\"http:\/\/www.pythonpool.com\/pythons-itertools-groupby\/\" target=\"_blank\" rel=\"noreferrer noopener\">itertools<\/a><\/strong><\/span> module. So import it. The group by function splits the list into desired keys. You need to specify the delimiter, and the groupby function will accordingly create the divisions. A simple for loop can be used to iterate over the set of values in the list. In addition to this, you can opt for other alternate ways too.<\/p>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\"
