In simple words, we can say that the properties associated or defined in any class or datatype are called its <span style=\"text-decoration: underline;\"><strong><a href=\"http:\/\/www.pythonpool.com\/python-check-if-object-has-attribute\/\" target=\"_blank\" rel=\"noreferrer noopener\">attribute<\/a><\/strong><\/span>.<\/p>\n\n\n\n<p>When we try to call or access any attribute on a value that is not associated with its class or data type. We get an attribute error. Let&#8217;s try to understand it more clearly. So when we define any variable or instance for any class or datatypes we have access to its attributes. We can use it for our operations but when we try to call an attribute that is not defined for that particular class we get the attribute error. I hope it is clear to you!<\/p>\n\n\n\n<p>Now, before moving to AttributeError: <strong>enter<\/strong>, let&#8217;s understand the concept of <a href=\"http:\/\/www.pythonpool.com\/python-mock-context-manager\/\" target=\"_blank\" rel=\"noopener\">Python Context Manager<\/a>. It will help us to understand the <span style=\"text-decoration: underline;\"><strong><a href=\"http:\/\/www.pythonpool.com\/attribute-error-python\/\" target=\"_blank\" rel=\"noreferrer noopener\">error<\/a><\/strong><\/span> clearly and then fix it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-python-context-manager\"><span class=\"ez-toc-section\" id=\"Python_Context_Manager\"><\/span>Python Context Manager<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>So, When we work on any real-time problems, there is the case that we have to handle different <strong>files and databases<\/strong> for storing and retrieving data. These files or databases are known as resources. When we try to access these files or databases then there is a supply constraint to them.  It means we can access only a limited number of files at once. So it is important to free all those resources on which we are not working. If we somehow failed to free those resources it will cause resource leakage and consequently, slow down the system.<\/p>\n\n\n\n<p>Now, think that when we handle more files and we have to write the same code, again and again, to open and then close the file. Therefore, to solve this problem we try to achieve the <strong>DRY ( Don&#8217;t Repeat Yourself )<\/strong> approach. <\/p>\n\n\n\n<p>Here, python <strong>Context Manager<\/strong> comes into the picture. It helps us to create different classes to manage those resources.  Python uses the &#8220;<strong>with<\/strong>&#8221; keyword to evaluate that whether the class or function is context manager or not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-to-create-context-manager\"><span class=\"ez-toc-section\" id=\"How_to_create_Context_Manager\"><\/span>How to create Context Manager<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>We can create a context manager by using both class and functions. We will discuss it one by one.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-using-class\">Using Class <\/h4>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nclass FileManager():             # defining context manager class named FileManager\n    def __init__(self, filename, mode):\n        self.filename = filename\n        self.mode = mode\n                 \n    def __enter__(self):\n        self.file = open(self.filename, self.mode)\n        return self.file\n      \n    def __exit__(self, exc_type, exc_value, traceback):\n        self.file.close()\n  \n# loading the file Sample.txt to work upon.\n\nwith FileManager('Sample.txt', 'w') as file:\n    file.write('Sample Testing')\n  \nprint(file.closed)\n<\/pre><\/div>\n\n\n<pre class=\"wp-block-code\"><code>Output: True<\/code><\/pre>\n\n\n\n<p>The given snippet of code describes how to create a Context Manager using the python class. Now, let&#8217;s try to understand each function in the defined class.<\/p>\n\n\n\n<p><strong>__init__<\/strong>:- This method is used to initialize objects for the given class. once, <a href=\"http:\/\/www.pythonpool.com\/fatal-python-error-py_initialize-unable-to-load-the-file-system-codec\/\" target=\"_blank\" rel=\"noopener\">initialization<\/a> is complete it invokes the __enter__ function.<\/p>\n\n\n\n<p><strong>__enter__<\/strong>:- The __enter__ function then opens the file in the defined mode and then returns an instance of FileManager class. Then the instance is stored in the &#8220;file&#8221; variable from this line of code( <strong>with FileManager(&#8216;Sample.txt&#8217;, &#8216;w&#8217;) as file<\/strong>: ). After this file.write will get executed. Once the writing operation is over, __exit__ function is called automatically.<\/p>\n\n\n\n<p><strong>__exit__<\/strong>:- This function closes the file without mentioning it explicitly every time.<\/p>\n\n\n\n<p>Now, to check whether the file is closed or not we wrote &#8220;print(file.closed)&#8221; which returns a <strong>true<\/strong> value which means that the file is closed.<\/p>\n\n\n\n<p>Now, we will imply the same functionality of context manager using functions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-using-functions\"><span class=\"ez-toc-section\" id=\"Using_Functions\"><\/span>Using Functions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<div class=\"wp-block-syntaxhighlighter-code \"><pre class=\"brush: python; title: ; notranslate\" title=\"\">\nfrom contextlib import contextmanager\n\n@contextmanager\ndef file_manager(file, mode):\n        # opens the file in given mode and assign it to the variable file.\n        file = open(file,mode)    \n        yield file                      #returns the file variable  \n        f.close()                       # closes the file\nwith open_file('sample.txt') as file:\n        file.write('Sample Testing')\n\nprint(f.closed)                 #returns true \n\n<\/pre><\/div>\n\n\n<pre class=\"wp-block-code\"><code>Output: True<\/code><\/pre>\n\n\n\n<p>So in this way, we can also implement context manager using functions.
