Repeated Value - Python Programming Exercise

In this exercise, you will develop a Python program that prompts the user for a number and a quantity, then displays that number repeated as many times as the user specifies. You will practice using both while loops and for loops to repeat an operation multiple times, which is a fundamental concept in Python programming. By completing this exercise, you will improve your understanding of loop structures in Python, specifically how to repeat tasks using while and for. This will help you create flexible Python programs that can handle dynamic input and perform repetitive tasks efficiently.

Repeated Value

 Objective

Develop a Python program that prompts the user for a number and a quantity, and displays that number repeated as many times as the user has specified. Here's an example:

Enter a number: 4
Enter a quantity: 5

44444

You must display it three times: first using "while" and then using "for".

 Example Python Exercise

 Copy Python Code 
# Prompt the user to enter a number
num = input("Enter a number: ")

# Prompt the user to enter a quantity
quantity = int(input("Enter a quantity: "))

# Display the number repeated as many times as specified using a while loop
i = 0
while i < quantity:
    print(num, end="")
    i += 1
print()  # Move to the next line

# Display the number repeated as many times as specified using a for loop
for _ in range(quantity):
    print(num, end="")
print()  # Move to the next line

# Display the number repeated as many times as specified using string multiplication
print(num * quantity)

 Output

Enter a number: 4
Enter a quantity: 5
44444
44444
44444
