​The endswith() function checks if a string ends with a suffix. If so, endswith() will return the boolean True, otherwise it will return the boolean false.


How to formulate it like this:


string. endswith(suffix, start, end)

suffix: A word, string, or tuple that must be checked

start: [Optional] Start the index where the search starts.

end: [optional] The end of the index where the search stops.

Return value: Returns a boolean value that is either true or false.


Note: If the start and end index is not provided, it will default to 0 and the -1 character as the start and end index.

In the following example we will check if the string ends in 'obaid'. If it is, endswith() will return the boolean True, otherwise it will return the boolean false.

Example:


# Define a variable
string1 = "learn python with ahmad  obaid"
# endswith a function call
print(string1.endswith("obaid")) # returns True
# Define a variable  
string2 = "Hello Python"
# endswith a function call
print(string2.endswith("obaid")) # returns False

Will beundefined The resulting:


True
False

 In the following example, we will check if the given word is between the start and end indexes. If so, the endswith() function will return the boolean True, and if not, it will return the boolean false.

 Note: The reason for adding start and end values ​​is that sometimes you need to supply a suffix/capital to be checked. Start and end parameters help you with this.

 Example:


# Define a variable  
string = "learn python with ahmad  obaid"
# endswith a function call 
print(string.endswith('obaid' , 22)) # returns True
# endswith a function call 
print(string.endswith('obaid' , 22,30)) # returns True
# endswith a function call
print(string.endswith('obaid' , 22, 28)) # returns False

 The output will be:


True
True
False

 In the following example we will check if the string contains a tuple. That is, if the string ends with any element of the tuple, the endswith() function will return the boolean value True, and if it is otherwise, it will return the boolean value false

 Example:


# Define a variable
string = "learn python with ahmad  obaid"
# endswith a function call
result = string.endswith(( 'Hello', 'python', 'obaid', 'mango')) # returns True 
# Print the result
print(result)
# Define a variable  
string = "obaid"
# endswith a function call 
result = string.endswith(('e', 'd', 'i', 'o', 'u')) # returns True
# Print the result
print(result)
# Define a variable 
string = "python"
# endswith a function call 
result = string.endswith(('e', 'a', 'i', 'o', 'u')) # returns False
# Print the result
print(result)

 The output will be:


True
True
False
