Converting integer to binary in Python

In order to convert an integer to a binary, I have used this code:

>>> bin(6)
'0b110'

and when to erase the '0b', I use this:

>>> bin(6)[2:]
'110'

What can I do if I want to show 6 as 00000110 instead of 110?

To convert an integer to a binary string with leading zeros, you can use the zfill() method to pad the string with zeros to a specific length, or use string formatting with the format() function.

Here are two ways to achieve the desired result of displaying 6 as 00000110:

1. Using zfill() method:

You can use bin(6)[2:].zfill(8) to pad the binary representation with zeros to make it 8 bits long.

num = 6
binary_str = bin(num)[2:].zfill(8)
print(binary_str)

Output:

00000110

2. Using format() function:

Another approach is to use the format() function, which allows you to specify the binary format and the desired width with leading zeros:

num = 6
binary_str = format(num, '08b')  # '08b' means 8-bit binary format with leading zeros
print(binary_str)

Output:

00000110

Both methods will give you the binary representation of the number 6 with 8 bits, including leading zeros.
