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

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
