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]*5print(a) # Initializing a list with all 0 a = [0]*10print(a) |
Output:
[True, True, True, True, True]
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
