How To Multiply Inputs In Python

In this tutorial, we will learn how to multiply inputs in Python using various methods. The process of multiplying inputs involves taking two or more input values and performing multiplication operations on them.

These operations can be done with the help of functions, loops, or even libraries if required. By the end of this tutorial, you will have a clear understanding of how to multiply inputs in Python.

Step 1: Using the Built-in Multiplication Operator

Python has a built-in multiplication operator *, which can be used to multiply two numbers directly. For example:

1
2
3
4
num1 = 3
num2 = 4
result = num1 * num2
print(result)
Output
12

In the above example, we multiplied the numbers 3 and 4 and stored the result in the variable result. We then printed the result on the screen.

However, in practical scenarios, you would probably have to get the numbers from the user as input before performing the multiplication. Let’s see how we can do this.

Step 2: Getting User Input and Performing Multiplication

In Python, we use the input() function to get user input. We can use this function to take inputs from the user and then multiply them.

Here’s an example:

# Get user inputs
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
 
# Perform multiplication
result = num1 * num2
 
# Display the result
print("The result of the multiplication is", result)
Output (Example)
Enter the first number: 5
Enter the second number: 6
The result of the multiplication is 30.0

In the above example, we used the input() function to get the user inputs as strings. We then converted the strings to float (to account for decimal values) and then multiplied them.

Now let’s see how to multiply a list of numbers entered by the user.

Step 3: Multiplying Multiple Numbers in a List

In this step, we will use a for loop to multiply a list of numbers.

Here’s how to do it:

1
2
3
4
5
6
7
8
9
10
11
12
# Get the list of numbers
numbers = input("Enter numbers separated by space: ").split()
 
# Initialize the result variable
result = 1
 
# Perform multiplication
for num in numbers:
    result *= float(num)
 
# Display the result
print("The result of the multiplication is", result)
Output (Example)
Enter numbers separated by space: 2 3 4
The result of the multiplication is 24.0

In the above example, we used the input() function to get the input as a string. We then used the .split() function to split the string by spaces and convert it to a list. We then used a for loop to iterate through the list and multiply the numbers.

print(result)
 
# Getting user input and performing multiplication
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
result = num1 * num2
print("The result of the multiplication is", result)
 
# Multiplying multiple numbers in a list
numbers = input("Enter numbers separated by space: ").split()
result = 1
for num in numbers:
    result *= float(num)
print("The result of the multiplication is", result)

Conclusion

In this tutorial, we learned how to multiply inputs in Python using various methods, such as the built-in multiplication operator and loops. We also learned how to get input from users and how to multiply multiple numbers from a list.
