The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string, a list, a tuple, or other objects ...
A simple way of checking if a file exists is by using theexists()function from theoslibrary. The function is shown below withexample_file.txt: importos os.path.exists('example_file.txt') Out: True Learn Data Science with In this case, the file exists, so theexists()function has returne...
Python’s in and not in operators allow you to quickly check if a given value is or isn’t part of a collection of values. This type of check is generally known as a membership test in Python. Therefore, these operators are known as membership operators....
