Python String endswith()

In this tutorial, we will learn about the Python String endswith() method with the help of examples.

The endswith() method returns True if a string ends with the specified suffix. If not, it returns False.

Example

message = 'Python is fun'

# check if the message ends with fun
print(message.endswith('fun'))

# Output: True

1. Syntax of String endswith()

The syntax of endswith() is:

str.endswith(suffix[, start[, end]])

2. endswith() Parameters

The endswith() takes three parameters:

• suffix – String or tuple of suffixes to be checked
• start (optional) – Beginning position where suffix is to be checked within the string.
• end (optional) – Ending position where suffix is to be checked within the string.

3. Return Value from endswith()

The endswith() method returns a boolean.

• It returns True if a string ends with the specified suffix.
• It returns False if a string doesn’t end with the specified suffix.

4. Example 1: endswith() Without start and end Parameters

text = "Python is easy to learn."

result = text.endswith('to learn')
# returns False
print(result)

result = text.endswith('to learn.')
# returns True
print(result)

result = text.endswith('Python is easy to learn.')
# returns True
print(result)

Output

False
True
True

5. Example 2: endswith() With start and end Parameters

text = "Python programming is easy to learn."

# start parameter: 7
# "programming is easy to learn." string is searched
result = text.endswith('learn.', 7)
print(result)

# Both start and end is provided
# start: 7, end: 26
# "programming is easy" string is searched

result = text.endswith('is', 7, 26)
# Returns False
print(result)

result = text.endswith('easy', 7, 26)
# returns True
print(result)

Output

True
False
True

6. Passing Tuple to endswith()

It’s possible to pass a tuple suffix to the endswith() method in Python.

If the string ends with any item of the tuple, endswith() returns True. If not, it returns False

7. Example 3: endswith() With Tuple Suffix

text = "programming is easy"
result = text.endswith(('programming', 'python'))

# prints False
print(result)

result = text.endswith(('python', 'easy', 'java'))

#prints True
print(result)

# With start and end parameter
# 'programming is' string is checked
result = text.endswith(('is', 'an'), 0, 14)

# prints True
print(result)

Output

False
True
True

If you need to check if a string starts with the specified prefix, you can use startswith() method in Python.
