+
+The **`str.removesuffix()`** method returns a new string with the specified suffix removed, if present. If the string does not end with the given suffix, the original string is returned unchanged. This method is case-sensitive and does not modify the original string.
+
+## Syntax
+
+```pseudo
+string_name.removesuffix(suffix)
+```
+
+**Parameters:**
+
+- `suffix`: The string to remove from the end of the original string.
+
+**Return value:**
+
+A new string with the suffix removed if it exists, otherwise, the original string.
+
+## Example 1: Removing a file extension
+
+This method can be used to remove a file extension when the suffix matches exactly:
+
+```py
+file_type = "Cat Store.docx"
+result = file_type.removesuffix('.docx')
+print(result)
+```
+
+The output would look like this:
+
+```shell
+Cat Store
+```
+
+## Example 2: Case sensitivity
+
+`.removesuffix()` is case-sensitive, so, if the case does not match exactly, the suffix is not removed:
+
+```py
+statement = "And when I silently snuck up on my mom, I jumped up and exclaimed 'BOO!'"
+result = statement.removesuffix('Boo!')
+print(result)
+```
+
+Here's the output:
+
+```shell
+And when I silently snuck up on my mom, I jumped up and exclaimed 'BOO!'
+```
+
+## Example 3: Removing text from a sentence
+
+The suffix must match the exact ending of the string, including punctuation:
+
+```py
+quote = 'Do or do not, there is no try (Yoda).'
+result = quote.removesuffix(' (Yoda).')
+print(result)
+```
+
+The output for this code would look like this:
+
+```shell
+Do or do not, there is no try
+```
