Create multiple copies of a string in Python by using multiplication operator

  • Difficulty Level : Easy
  • Last Updated : 16 Nov, 2021

In this article, we will see how to create multiple copies of a string by using the multiplication operator(*). Python supports certain operations to be performed on a string, multiplication operator is one of them.

Method 1: 

Simply using multiplication operator on the string to be copied with the required number of times it should be copied.


str2 = str1 * N

where str2 is the new string where you want to store the new string

str1 is the original string

N is the number of the times you want to copy the string.

After using multiplication operator we get a string as output

Example 1:


# Original string
a = "Geeks"
# Multiply the string and store
# it in a new string
b = a*3
# Display the strings
print(f"Original string is: {a}")
print(f"New string is: {b}")


Original string is: Geeks

New string is: GeeksGeeksGeeks

Example 2:


# Initializing the original string
a = "Hello"
n = 5
# Multiplying the string
b = a*n
# Print the strings
print(f"Original string is: {a}")
print(f"New string is: {b}")


Original string is: Hello

New string is: HelloHelloHelloHelloHello

Method 2: Copying a string multiple times given in a list

If we have a string as a list element, and we use the multiplication operator on the list we will get a new list that contains the same element copied specified number of times.


a  = [“str1”] * N

a will be a list that contains str1 N number of times.

It is not necessary that the element we want to duplicate in a list has to be a string. Multiplication operator in a list can duplicate anything.

Example 3:


# Initialize the list
a = ["Geeks"]
# Number of copies
n = 3
# Multiplying the list elements
b = a*n
# print the list
print(f"Original list is: {a} ")
print(f"List after multiplication is: {b}")


Original list is: [‘Geeks’]  

List after multiplication is: [‘Geeks’, ‘Geeks’, ‘Geeks’]

Example 4: Shorthand method for the same approach


# initializing a string with all True's
a = [True]*5
# Initializing a list with all 0
a = [0]*10


[True, True, True, True, True]

[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
