How to check whether a string ends with one from a list of suffixes in Python?

Python has a method endswith(tuple) in the String class. This method accepts a tuple of strings that you want to search and is called on a string object. You can call this method in the following way:

string = 'core java'
print(string.endswith(('txt', 'xml', 'java', 'orld')))

OUTPUT

True

There is another way to find if a string ends with a given list of suffixes. You can use re.search from the re module(regular expression) to do so. Regex interprets $ as end of line. We also need to seperate out the suffixes using grouping and | symbol in regex. For example,

import re
string = 'core java'
print(bool(re.search('(java|xml|py|orld)$', string)))
print(bool(re.search('(java|xml|py|orld)$', 'core java')))
print(bool(re.search('(java|xml|py)$', 'Hello world')))

OUTPUT

True
True
False

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 here.
