Python endswith

by

Python endswith method is one of the String Method which returns Boolean TRUE, if the string Ends with the specified substring otherwise, it will return False.

In this article we will show you, How to write endswith Function in Python Programming with example.

TIP: The Python endswith Function is very useful, when we want to check the ending term of a User inputs.

Python endswith Syntax

The basic syntax of the Python endswith function is as shown below:

String_Value.endswith(Substring, Starting_Position, Ending_Position)
  • String_Value: Please select the valid String literal.
  • Substring: Please specify the string you want to search for.
  • Starting_Position: This is an optional parameter. If you want to specify the starting point (starting index position) then, Please specify the index value here. If you Omit this parameter then, the string endswith Function will consider Zero as starting position.
  • Ending_Position: This is an optional parameter. If you want to specify the end point (Ending index position) then, Please specify the index value here. If you Omit this parameter then, endswith() Function will consider the highest index number

Python endswith method Example

The following set of examples will help you understand the endswith() Function in Python.

# endswith Method Example

Str1 = 'Learn Python at Tutorial Gateway';
Str2 = Str1.endswith('Gateway')
print('First Output of a EndsWith() method is = ', Str2)

# Performing EndsWith() function directly
Str3 = 'Find Tutorial at Tutorial Gateway'.endswith('Gateway')
print('Second Output of a EndsWith() method is = ', Str3)

# Using First Index while finding the String
Str5 = Str1.endswith('Python', 6, 12)
print('Third Output of a EndsWith() method is = ', Str5)

# Searching for Non existing String
Str7 = Str1.endswith('Python')
print('Fourth Output of a EndsWith() method is = ', Str7)

OUTPUT

Python EndsWith

ANALYSIS

First we declared the String variable Str1 and assigned corresponding value using following statement

Str1 = 'Learn Python at Tutorial Gateway';

Following statement will check whether the string Str1 is ended with the term ‘Gateway’ or not using EndsWith() function and prints the output

Str2 = Str1.endswith('Gateway')
print('First Output of a EndsWith() method is = ', Str2)

The Python endswith function allows us to use it directly on string literal. Following statement will show the same

Str3 = 'Find Tutorial at Tutorial Gateway'.endswith('Gateway')
print('Second Output of a EndsWith() method is = ', Str3)

The string endswith function allows us to use Starting and ending indices. By specifying starting and ending index position we can increase the performance. Following statement will start looking from position 6 and check whether the keyword ‘Python’ is at position 12 or not.

Str5 = Str1.endswith('Python', 6, 12)
print('Third Output of a EndsWith() method is = ', Str5)

If the string endswith function in Python does not find the specified string at the ending point, it will return Boolean False. Following statement is returning Flase because, this function will start looking for term ‘Python’ and we all know that, Str1 is ending with ‘Gateway’.

Str7 = Str1.endswith('Python')
print('Fourth Output of a EndsWith() method is = ', Str7)
