Python String rstrip()

The Python String rstrip() method is a built-in function that strips trailing characters based on the arguments passed to the function and returns the copy of a string.

Also read TypeError: can’t multiply sequence by non-int of type ‘str’

In this article, we will learn about the Python String rstrip() method with the help of examples.

rstrip() Syntax

The Syntax of rstrip() method is:

string.rstrip([chars])

rstrip() Parameters

The rstrip() method takes one parameter, and it’s optional.

• chars(optional) – set of characters representing string that needs to be removed from the right-hand side of the string.

If the chars argument is not passed, the rstrip() function will strip whitespaces at the end of the string.

rstrip() Return Value

The rstrip() method returns a copy of the string by stripping the trailing characters based on the arguments passed.

Note:

• If we do not pass any arguments to rstrip() function, by default, all trailing whitespaces are truncated from a string.
• If the string does not have any whitespaces at the end, the string will be returned as-is, matching the original string.
• If the characters passed in the arguments do not match the characters at the end of the string, it will stop removing the trailing characters.

Example 1: Working of rstrip()

# Only trailing whitespaces are removed
text1 = ' Python Programming '
print(text1.rstrip())

# Remove the whitespace and specified character at
# trailing end
text2 = ' code its my code '
print(text2.rstrip(' code'))

# Remove the specified character at 
# trailing end
text3 = 'code its my code'
print(text3.rstrip('code'))

Output

   Python Programming
       code its my
code its my

Example 2 – How to use rstrip() method in real world?

In the below example, we have a list of the price in dollars. However the dollar sign is appended at both the trailing and leading end of each element. We can simply iterate the list and remove the dollar symbol at the right hand side using the rstrip() method as shown below.

price = ['$100$', '$200$', '$300$', '$400$', '$500$']
new_price = []
for l in price:
    new_price.append(l.rstrip('$'))

print(new_price)

Output

['$100', '$200', '$300', '$400', '$500']
