Hello in this tutorial, we will explain the String find() method in Python programming.<\/p>\n

1. Introduction<\/h2>\n

The find()<\/code> method in python programming is used to find the occurrence of a character in a given string or a substring of a string. The method is represented by the following syntax.<\/p>\n

string.find(search_char, start, end)\n\nwhere,\nsearch_char specifies the string to be searched\nstart is optional and the default value is 0\nend is optional and the default value is the end of the string\n<\/pre>\n
\n
\"Python<\/a><\/figure>\n<\/div>\n
The method returns the index of the first occurrence of the given character inside the string. The method returns -1<\/code> if the value doesn\u2019t exist inside the string. The method is different from the index()<\/code> method as the latter one raises an exception if the value is not found.<\/p>\n
1.1 Setting up Python<\/h3>\n
If someone needs to go through the Python installation on Windows, please watch this<\/a> link. You can download the Python from this<\/a> link.

2. Python String find() method Tutorial<\/h2>\n
I am using JetBrains PyCharm<\/a> as my preferred IDE. You are free to choose the IDE of your choice. Let us dive in with the programming stuff now.<\/p>\n
2.1 Python String find() method Tutorial<\/h3>\n
Let us understand the different use cases of the find()<\/code> method in python programming.<\/p>\n
find() method<\/em><\/span><\/p>\n
# python string find() tutorial\n# a. Returns the first occurrence of the given value\n# b. If not found returns -1\n# Syntax - string.find(search_char, start, end)\n# where,\n# start is optional and the default value is 0\n# end is optional and the default value is the end of the string\nstring = 'Hello world! Welcome to javacodegeeks.'\ndef find(search_char):\n    index = string.find(search_char)\n    if index != -1:\n        print('{} is present at index = {}'.format(search_char, index))\n    else:\n        print('{} is not present in string'.format(search_char))\ndef find_range(search_char, start, end):\n    index = string.find(search_char, start, end)\n    if index != -1:\n        print('{} is present in the given range at index = {}'.format(search_char, index))\n    else:\n        print('{} is not present in string'.format(search_char))\n# driver code\nif __name__ == '__main__':\n    find('w')\n    find('y')\n    find_range('e', 1, 10)\n    find_range('x', 1, 5)\n<\/pre>\n
If everything goes well the following output will be shown in the IDE console.<\/p>\n
Console Output<\/em><\/span><\/p>\n
w is present at index = 6\ny is not present in string\ne is present in the given range at index = 1\nx is not present in string\n<\/pre>\n
That is all for this tutorial and I hope the article served you with whatever you were looking for. Happy Learning and do not forget to share!<\/p>\n
