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

  • Last Updated : 03 Jan, 2021

In t his 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.

Syntax:

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:

Python3




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

Output:

Orignal string is: Geeks

New string is: GeeksGeeksGeeks

Example 2:



Python3




# Intializing the orignal stirng
a = "Hello"
n = 5
  
# Multiplying the stirng
b = a*n
  
# Print the strings
print(f"Orignal string is: {a}")
print(f"New string is: {b}")

Output:

Orignal 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.

Syntax:

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:

Python3




# 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}")

Output:



Original list is: [‘Geeks’]  

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

Example 4: Shorthand method for the same approach

Python3




# initializing a stirng with all True's
a = [True]*5
print(a)
  
# Initializing a list with all 0
a = [0]*10
print(a)

Output:

[True, True, True, True, True]

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