Python bytes.rstrip Usage Detailed Explanation and Examples

bytes.rstrip() is a Python method used to remove specified characters or strings from the end of a bytes object.

Its syntax is as follows:

bytes.rstrip([chars])

The chars parameter is optional and specifies the characters or strings to be removed from the end of the bytes object. If the chars parameter is not specified, the rstrip() method will remove all whitespace characters (including spaces, tabs, and newlines) by default.

Next, I will provide three examples to illustrate the use of bytes.rstrip().

Example 1: Trimming Trailing Spaces from a Bytes Object

b = b"hello world "
result = b.rstrip()
print(result) # Output: b"hello world"

In this example, we define a bytes object b with trailing spaces. By calling the b.rstrip() method, we trim all trailing spaces and assign the result to the result variable. Finally, we print the result.

Example 2: Remove Specific Characters from the End of a Bytes Object

b = b"hello world!!!"
result = b.rstrip(b"!")
print(result) # Output: b"hello world"

In this example, we define a bytes object b with multiple exclamation points at the end. By calling the b.rstrip(b"!") method, we remove all the exclamation points and assign the result to the result variable. Finally, we print the result.

Example 3: Removing a Specified String from the End of a Bytes Object

b = b"hello worldfoobar"
result = b.rstrip(b"bar")
print(result) # Output: b"hello worldfoo"

In this example, we define a bytes object b with the string “bar” at the end. By calling the b.rstrip(b"bar") method, we remove the “bar” string from the end and assign the result to the result variable. Finally, we print the result.
