The Python String lstrip() method is a built-in function that strips leading characters based on the arguments passed to the function and returns the copy of a string.
In this article, we will learn about the Python String
lstrip() method with the help of examples.
The Syntax of
lstrip() method is:
lstrip() method takes one parameter, and it’s optional.
- chars(optional) – set of characters representing string that needs to be removed from the left-hand side of the string.
If the chars argument is not passed, the
lstrip() function will strip whitespaces at the start of the string.
lstrip() Return Value
lstrip() method returns a copy of the string by stripping the leading characters based on the arguments passed.
- If we do not pass any arguments to
lstrip()function, by default, all leading whitespaces are truncated from a string.
- If the string does not have any whitespaces at the beginning, 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 beginning of the string, it will stop removing the leading characters.
Example 1: Working of lstrip()
# Only leading whitespaces are removed text1 = ' Python Programming ' print(text1.lstrip()) # Remove the whitespace and specified character at # leading end text2 = ' code its my code ' print(text2.lstrip(' code')) # Remove the specified character at # leading end text3 = 'code its my code' print(text3.lstrip('code'))
Python Programming its my code its my code
Example 2 – How to use lstrip() 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 left hand side using the
lstrip() method as shown below.
price = ['$100$', '$200$', '$300$', '$400$', '$500$'] new_price =  for l in price: new_price.append(l.lstrip('$')) print(new_price)
['100$', '200$', '300$', '400$', '500$']
