Python String Exercises: Display a number with a comma separator

Sample Solution:

Python Code:

# Define a variable 'x' and assign it the value 3,000,000 (an integer).
x = 3000000

# Define a variable 'y' and assign it the value 30,000,000 (an integer).
y = 30000000

# 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 a comma separator for thousands and print it.
print("Formatted Number with comma separator: "+"{:,}".format(x))

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

# Format the value of 'y' with a comma separator for thousands and print it.
print("Formatted Number with comma separator: "+"{:,}".format(y))

# Print an empty line for spacing.
print()

Sample Output:

Original Number:  3000000
