Understanding Python String endswith()

Python string endswith() is an inbuilt function which returns true in the case, if the string ends with a particular specified suffix; else it will returns false.

• In this case, if the start and end index is not specified then by default start is taken as 0 and length is taken as -1 and ending index is not included in our search.
• If the string is ending with a suffix that is used in endswith() function then the function will returns **true** otherwise, it will return false.
• If you want to check that string ends with one of the strings from the list then in that case string endswith() function is used.
• This method returns the boolean value.
• This function also accepts tuple; we will show you with the help of examples

Below we have a basic syntax of String endswith() in Python:

string.endswith(suffix, start, end)

Python String **endswith()**: Parameters

The description of the Parameters of endswith() is given below:

• suffix

This parameter is used to specify the part of the string for which we will check if the string is ending with that part or not.

• start

It is an optional parameter and from here suffix will start.

• end

It is an optional parameter and the suffix will end here.

Python String **endswith()**: Returned Values

For the returned value there are two cases:

• It returns true in the case if the string ends with a specified suffix.
• It returns false in the case if the string does not end with a specified suffix.

Below we have an example to show the working of String endswith() function:

string = "Hello I am Ram and I am a developer"

result = string.endswith("per")
result1 = string.endswith("PER")
print("Comparing it with right suffix so output: ",result)
print("Comparing it with wrong suffix so output: ",result1)

The Output for the same is given below:

Comparing it with right suffix so output: True Comparing it with wrong suffix so output: False

In the example given below, we will use both start and end parameter of endswith(). Let us see the code snippet:

abc = "This is a string and is awesome"
right_suffix = "some"
wrong_suffix = "some!"
print(abc.endswith(right_suffix, 28, 31))
print(abc.endswith(wrong_suffix, 28, 31))

The Output for the same is given below:

false false

In this example, we are checking if the string ends with one of the strings in the Tuple. Let us see the code snippet:

text = "StudyTonight"
result = text.endswith(('Study', 'Otis'))

print(result)

result = text.endswith(('Study', 'night'))

print(result)

The Output for the same is given below:

false true

In this example, we are checking if the string ends with one of the strings in the List. Let us see the code snippet:

ext = ['.jpg','.png']
file = 'test.png'

print(file.endswith(('.jpg', '.png')))

The Output for the same is given below:

true

In this tutorial, we learned endswith() method with a description of its parameters and returned values. We have also used tuple and list as a suffix. Also, there is a live example of endswith() method.
