The endswith() function in python helps to check whether a string end with a given suffix. If yes the function returns true else false.
str.endswith(suffix[, start[, end]]) #where index is an integer value
The endswith() function takes three parameters. If the starting and ending prefix is not specified, then by default it will check the whole string starting from zero indexes.
| Parameter | Description | Required / Optional |
|---|---|---|
| suffix | String or tuple of suffixes to be checked | Required |
| start | Starting position where suffix is to be checked within the string | optional |
| end | Ending position where suffix is to be checked within the string | optional |
The return value is always a boolean value. It is also possible to pass tuple suffixes to this method. If the string end with any element of the tuple this function returns true.
| Input | Return Value |
|---|---|
| if strings end with the specified suffix | True |
| if string doesn't end with the specified suffix | False |
string = "Hii, How are you?"
result = string.endswith('are you')
# returns False
print(result)
result = string.endswith('are you?')
# returns True
print(result)
result = string.endswith('Hii, How are you?')
# returns True
print(result)
Output:
False True True
string = "Hii, How are you?"
# start parameter: 10
result = string.endswith('you?', 10)
print(result)
# Both start and end is provided
result = string.endswith('are?', 2, 8)
# Returns False
print(result)
result = string.endswith('you?', 10, 16)
# returns True
print(result)
Output:
True False True
string = "apple is a fruit"
result = string.endswith(('apple', 'flower'))
# prints False
print(result)
result = string.endswith(('apple', 'fruit', 'grapes'))
#prints True
print(result)
# With start and end parameter
result = string.endswith(('is', 'to'), 0, 8)
# prints True
print(result)
Output:
True False True
