Practical 2: program to append a string to another string using the += operator.
Problem Statement
Write a Python program to append a string to another string using the += operator.
The program should:
- Accept two strings as input from the user.
- Append the second string to the first string using the += operator.
- Display the updated string.
Solution Code
# Program to append a string using += operator
# Input: Take two strings from the user
str1 = input("Enter the first string: ")
str2 = input("Enter the string to append: ")
# Appending using += operator
str1 += str2
# Output the updated string
print("Updated String:", str1)
Output
- The program will take two string inputs from the user.
- It will append the second string to the first using the += operator.
- The result will be displayed.
Example output:
Enter the first string: Hello
Enter the string to append: World
Updated String: HelloWorld
Process finished with exit code 0
Explanation
Below is the explanation of F.E. PPS Unit 3 Practical 2 solution where we have written program to append a string to another string using the += operator.
- Taking Input from the User:
- The input() function is used to take two strings from the user and store them in str1 and str2.
- Appending Using += Operator:
- The += operator is used to modify str1 by appending str2 to it.
- This is equivalent to str1 = str1 + str2.
- Displaying the Result:
- The updated string is printed using the print() function.
Key Concept Learned
- Appending Strings Using += Operator:
- The += operator allows modifying a string by adding another string to it.
- Immutable Nature of Strings:
- In Python, strings are immutable, but when += is used, a new string is created and assigned to the variable.
- Handling User Input with Strings:
- Demonstrates how to take and manipulate string input.
