How to Convert Integers to Binary with Zero-Padding in Python?

Converting Integer to Binary in Python with Zero-Padding

When converting integers to binary using the bin() function in Python, you may encounter situations where you need to display the binary representation with zero-padding for leading zeros. Here's how you can achieve that:

Using the format() function:

<code class="python">>>> '{0:08b}'.format(6)
'00000110'</code>

The formatting string {0:08b} consists of the following parts:

• {0}: Placeholder for the variable at argument position 0
• 0: Zero-padding on the left
• 8: Pad to a total of 8 digits
• b: Convert to binary representation

Using f-strings (Python 3.6 ):

<code class="python">>>> f'{6:08b}'
'00000110'</code>

F-strings provide a more concise syntax for string formatting:

• f'{x}': Variables can be embedded directly into the string using f-strings
• 08b: Same formatting options as in the format() function

With these methods, you can easily convert integers to binary representations with the desired number of leading zeros.
