How to check if string or a substring of string ends with suffix in Python?
Python has a method endswith(string) in the String class. This method accepts a suffix string that you want to search and is called on a string object. You can call this method in the following way:
string = 'C:/Users/TutorialsPoint1/~.py'
print(string.endswith('.py'))OUTPUT
True
There is another way to find if a string ends with a given suffix. You can use re.search(suffix + '$', string) from the re module(regular expression) to do so. Regex interprets $ as end of line, so if you want to search for a suffix, you need to do the following:
string = 'C:/Users/TutorialsPoint1/~.py'
import re
print(bool(re.search('py$', string)))OUTPUT
True
re.search returns an object, to check if it exists or not, we need to convert it to a boolean using bool(). You can read more about Python regex <a href="https://docs.python.org/2/library/re.html" target="_blank">here</a>.
