Python lstrip

by

lstrip()

Python lstrip method is one of the Python String Method which is used to remove the specified characters from Left hand side of a string (By default, White spaces) and returns the new string. In this article we will show you, How to write lstrip() Function in Python Programming with example.

Python lstrip Syntax

The basic syntax of the Python lStrip function is as shown below:

String_Value.lStrip(Chars)
  • String_Value: Please select the valid String literal.
  • Chars: This parameter is optional and if you Omit this, lstrip() Function will consider the white spaces as default parameter. In order to change the default value, Please specify the Characters you want to strip from the string.

Python lstrip method Example

The following set of examples will help you understand the Python lstrip() Function.

PYTHON CODE

# Python lStrip Method Example

Str1 = '  Tutorial Gateway'

Str2 = Str1.lstrip()
print('Stripping Whitespaces on Left using lStrip() is =', Str2)

# Observe the Original String
print('Converted String is =', Str1.lstrip())
print('Original String is =', Str1)

# Performing lStrip() function directly
Str3 = '00000000Tutorial Gateway00000000'.lstrip('0')
print("Stripping 0's on Left using lStrip() is =", Str3)

# Stripping Left Side
Str4 = '+++++*********Tutorial Gateway'.lstrip('+*')
print('Stripping + and * on Left using lStrip() is =', Str4)

OUTPUT

ANALYSIS

First we declared the String variable Str1 and assigned corresponding value using following statement

Str1 = '  Tutorial Gateway'

Following statement will remove the white spaces from the Left hand side of String variable Str1 using lStrip() function and prints the output

Str2 = Str1.lstrip()
print('Stripping Whitespaces on Left using LStrip() is =', Str2)

The lStrip() function in Python will return the output in new string, instead of altering the original string. Following statements will show you the same

print('Converted String is =', Str1.lstrip())
print('Original String is =', Str1)

From the above screenshot you can observe that the, original string Str1 is unchanged. If you want to change the original String, you can write the following statement

Str1 = Str1.lstrip()

The Python lstrip function will only remove the specified characters from Left hand side of a string and omit right hand side characters. Within the following statements we have zeros on both sides but if you notice the above screenshot, the function output is removing zeros from Left hand side only.

Str3 = '00000000Tutorial Gateway00000000'.lstrip('0')
print("Stripping 0's on Left using LStrip() is =", Str3)

Here, we used two characters to strip (+ and *) from Left hand side

Str4 = '+++++*********Tutorial Gateway'.lstrip('+*')
print('Stripping + and * on Left using LStrip() is =', Str4)
