# How Do You Make Python Show 00 After The Number

Python Programming

Have you ever wondered how to make Python display 00 after a number? Well, I’ve delved into this and I’m excited to share what I’ve discovered. Let’s explore this together.

## Understanding the Problem

In Python, when you want to display a number with a fixed number of digits, it’s essential to use formatting. This is particularly useful when dealing with time, where you want to ensure that minutes, seconds, or milliseconds are always displayed as two digits, with a leading zero if necessary.

## Solution using String Formatting

One simple way to achieve this is by using string formatting with the `format()` method. Let’s say we have a number, `num = 5`, and we want to display it as “05”. We can accomplish this using the following code:

``` num = 5 formatted_num = '{:02d}'.format(num) print(formatted_num) # Output: 05 ```

In the above code, `'{:02d}'` is the format specifier. The `0` indicates that we want to pad with zeros, the `2` specifies the width, and the `d` is for integers.

## Using f-strings (Python 3.6 and above)

If you are using Python 3.6 or above, you can also achieve the same result using f-strings. Here’s how you can do it:

``` num = 5 formatted_num = f'{num:02d}' print(formatted_num) # Output: 05 ```

## Personal Experience

When I first encountered the need to display numbers with leading zeros, it was a bit confusing. However, after understanding string formatting and its various options, I found it to be a powerful and elegant solution.

## Conclusion

In conclusion, formatting numbers to display leading zeros in Python is a common requirement, especially in scenarios like time formatting. Whether you choose the `format()` method or f-strings, both provide convenient ways to achieve this. I hope this article has shed light on this topic and will be helpful in your Python journey.
