Python | Ways to remove n characters from start of given string

Last Updated : 07 Jun, 2019

Given a string and a number ‘n’, the task is to remove a string of length ‘n’ from the start of the string. Let’s a few methods to solve the given task.

Method #1: Using Naive Method

# Python3 code to demonstrate 
# how to remove 'n' characters from starting
# of a string
  
# Initialising string
ini_string1 = 'garg_akshat'
  
# Initialising number of characters to be removed
n = 5
  
# Printing initial string
print ("Initial String", ini_string1)
  
# Removing n characters from string using 
# Naive method
res = ''
for i in range(0, len(ini_string1)):
    if i>= n:
        res = res + ini_string1[i]
          
# Printing resultant string
print ("Resultant String", res)

Output:

Initial String garg_akshat
Resultant String akshat

Method #2: Using replace()

# Python3 code to demonstrate 
# how to remove 'n' characters from starting
# of a string
  
# Initialising string
ini_string1 = 'garg_akshat'
  
# Initialising number of characters to be removed
n = 5
  
# Printing initial string
print ("Initial String", ini_string1)
  
# Removing n characters from string using 
# replace() function
res = ini_string1.replace(ini_string1[:5], '', 1)
          
# Printing resultant string
print ("Resultant String", res)

Output:

Initial String garg_akshat
Resultant String akshat

Method #3: String slicing

# Python3 code to demonstrate 
# how to remove 'n' characters from starting
# of a string
  
# Initialising string
ini_string1 = 'gargakshat123'
  
# Initialising number of characters to be removed
n = 5
  
# Printing initial string
print ("Initial String", ini_string1)
  
# Removing n characters from a string
# This argument count length from zero 
# So length to be stripped is passed n-1
res = ini_string1[4:]
          
# Printing resultant string
print ("Resultant String", res)
     

Output:

Initial String gargakshat123
Resultant String akshat123
