How to calculate the percentage of a number in Python.

Here's the step-by-step tutorial on how to calculate the percentage of a number in Python:

Step 1: Obtain the number and the percentage value from the user.​

To start, you need to get the number for which you want to calculate the percentage and the percentage value itself. You can do this by using the input() function and asking the user to enter the values. Here's an example:

number = float(input("Enter the number: "))
percentage = float(input("Enter the percentage value: "))

Step 2: Calculate the percentage.​

To calculate the percentage, you need to multiply the number with the percentage value divided by 100. This can be done using the following formula:

percentage = number * percentage / 100

Here's an example of how to calculate the percentage in Python:

result = number * percentage / 100

Step 3: Display the result.​

Finally, you need to display the result to the user. You can use the print() function to do this. Here's an example:

print("The percentage is:", result)

Putting it all together, here's a complete example that calculates the percentage of a number:

number = float(input("Enter the number: "))
percentage = float(input("Enter the percentage value: "))

result = number * percentage / 100

print("The percentage is:", result)

That's it! You now know how to calculate the percentage of a number in Python.
