Last update on March 21 2025 12:53:31 (UTC/GMT +8 hours)

Format number as percentage.

Write a Python program to format a number with a percentage.

Sample Solution:

Python Code:

# Define a variable 'x' and assign it the value 0.25 (a floating-point number).
x = 0.25

# Define a variable 'y' and assign it the value -0.25 (a floating-point number).
y = -0.25

# 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' as a percentage with two decimal places and print it.
print("Formatted Number with percentage: "+"{:.2%}".format(x))

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

# Format the value of 'y' as a percentage with two decimal places and print it.
print("Formatted Number with percentage: "+"{:.2%}".format(y))

# Print an empty line for spacing.
print()

Sample Output:

Original Number:  0.25                                                                                        
Formatted Number with percentage: 25.00%                                                                      
Original Number:  -0.25                                                                                       
Formatted Number with percentage: -25.00%
