Print integers with left-padded zeros.

Write a Python program to print the following integers with zeros to the left of the specified width.

Sample Solution:

Python Code:

# Define a variable 'x' and assign it the value 3 (an integer).
x = 3

# Define a variable 'y' and assign it the value 123 (an integer).
y = 123

# Print an empty line for spacing.
print()

# Print the original value of 'x' with a label.
print("Original Number: ", x)

# Format the value of 'x' with left padding using zeros to a width of 2 characters and print it.
print("Formatted Number (left padding, width 2): "+"{:0>2d}".format(x))

# Print the original value of 'y' with a label.
print("Original Number: ", y)

# Format the value of 'y' with left padding using zeros to a width of 6 characters and print it.
print("Formatted Number (left padding, width 6): "+"{:0>6d}".format(y))

# Print an empty line for spacing.
print()

Sample Output:

Original Number:  3                                                                                           
Formatted Number(left padding, width 2): 03                                                                   
Original Number:  123                                                                                         
Formatted Number(left padding, width 6): 000123
