Python 9x9 Multiplication Table

Introduction

In this article, I will guide you on how to implement the "Python 9x9 Multiplication Table" using nested loops. This is a common exercise for beginners to practice their programming skills. By the end of this article, you will be able to generate a 9x9 multiplication table using Python.

Step-by-Step Process

To create the Python 9x9 Multiplication Table, we will follow the below steps:

Step	Description
1	Create a loop to iterate over the numbers 1 to 9 for the rows.
2	Within the first loop, create another loop to iterate over the numbers 1 to 9 for the columns.
3	Multiply the current row number with the current column number to get the multiplication result.
4	Print the multiplication result in a formatted way.
5	Repeat steps 3 and 4 until all the rows and columns are covered.

Now, let's dive into the implementation details.

Step 1: Outer Loop for Rows

The first step is to create a loop to iterate over the numbers 1 to 9 for the rows. We will use a for loop for this.

for row in range(1, 10):
    # Code for inner loop and multiplication goes here

Step 2: Inner Loop for Columns

Within the outer loop, we need to create another loop to iterate over the numbers 1 to 9 for the columns. Again, we will use a for loop for this.

for row in range(1, 10):
    for col in range(1, 10):
        # Code for multiplication and printing goes here

Step 3: Multiplication

Inside the inner loop, we need to multiply the current row number with the current column number to get the multiplication result. We will store this result in a variable called result.

for row in range(1, 10):
    for col in range(1, 10):
        result = row * col
        # Code for printing goes here

Step 4: Print the Result

After calculating the multiplication result, we need to print it in a formatted way. We will use the print() function for this.

for row in range(1, 10):
    for col in range(1, 10):
        result = row * col
        print(f"{row} x {col} = {result}", end="\t")
    print()

In the above code, we use f-string formatting to display the row number, column number, and the multiplication result. The end="\t" parameter ensures that each result is separated by a tab.

Step 5: Complete the Loop

Finally, we need to complete the loops by adding the closing brackets.

for row in range(1, 10):
    for col in range(1, 10):
        result = row * col
        print(f"{row} x {col} = {result}", end="\t")
    print()
