Python String endswith()

Summary: in this tutorial, you’ll learn how to use the Python string endswith() method to check if a string ends with another string.

Introduction to the Python string endswith() method #

The endswith() is a string method that returns True if a string ends with another string. Otherwise, it returns False.

The following illustrates the syntax of the endswith() method:

str.endswith(suffix, [,start [,end ])Code language: CSS (css)

The endswith() method has three parameters:

• suffix is a string or a tuple of strings to match in the str. If the suffix is a tuple, the method will return True if the str ends with one of the string element in the tuple. The suffix parameter is mandatory.
• start is the position that the method starts searching for the suffix. The start parameter is optional.
• end is the position in the str that the method stops searching for the suffix. The end parameter is also optional.

The endswith() method searches for the suffix case-sensitively.

To determine if a string starts with another string, you use the string startswith() method.

Python string endswith() method examples #

Let’s take some examples of using the string endswith() method.

1) Using the Python string endswith() method to determine if a string ends with another string #

The following example uses the string endswith() method to determine if a string ends with another string:

s = 'Beautiful is better than ugly'
result = s.endswith('ugly')
print(result)Code language: PHP (php)

Output:

TrueCode language: PHP (php)

As mentioned above, the endswith() method matches the string case-sensitively. So the following example returns False:

s = 'Beautiful is better than ugly'
result = s.endswith('UGLY')
print(result)Code language: PHP (php)

Output:

FalseCode language: PHP (php)

2) Using the Python string endswith() method with a tuple #

The following example uses the endswith() method to check if a sentence ends with a fullstop (.), a question mark (?), or an exclamation mark (!):

marks = ('.', '?', '!')
sentence = 'Hello, how are you?'
result = sentence.endswith(marks)

print(result)Code language: PHP (php)

Output:

TrueCode language: PHP (php)

Summary #

• Use the Python string endswith() method to determine if a string ends with another string.
