Unleash the Power of Python’s endswith() Method

Understanding the Syntax

The endswith() method takes three parameters: suffix, start, and end. The suffix parameter is a string or tuple of suffixes to be checked, while start and end are optional parameters that specify the beginning and ending positions where the suffix is to be checked within the string.

How it Works

The endswith() method returns a boolean value, indicating whether the string ends with the specified suffix. If the string does end with the suffix, it returns True; otherwise, it returns False.

Examples in Action

Let’s see the endswith() method in action:

my_string = "Hello, World!"
print(my_string.endswith("World!"))  # Output: True
print(my_string.endswith("Universe"))  # Output: False

In our second example, we’ll specify start and end parameters:

my_string = "Hello, World!"
print(my_string.endswith("World!", 7, 13))  # Output: True
print(my_string.endswith("Universe", 7, 13))  # Output: False

Using Tuples with endswith()

One powerful feature of the endswith() method is the ability to pass a tuple of suffixes. If the string ends with any item in the tuple, the method returns True. Let’s see an example:

my_string = "Hello, World!"
suffixes = ("World!", "Universe", "Galaxy")
print(my_string.endswith(suffixes))  # Output: True

Checking Prefixes with startswith()

While endswith() checks if a string terminates with a suffix, you can use the startswith() method to check if a string begins with a specific prefix.

By mastering the endswith() method, you’ll unlock new possibilities for string manipulation and analysis in Python. Take your skills to the next level and explore more advanced string methods, such as find() and count().
