Zero Padding in Python

We can easily pad the binary using Python.

Zero-padding to 8-bit

For zero-padding to 8-bit, specify 8 as the argument in the zfill method.

'1101'.zfill(8)
# 00001101

'101011'.zfill(8)
# 00101011

Zero-padding to 16-bit

For zero-padding to 16-bit, specify 16 as the argument in the zfill method.

'1101'.zfill(16)
# 0000000000001101

'11100110'.zfill(16)
# 0000000011100110

Zero-padding to 32-bit

For zero-padding to 32-bit, specify 32 as the argument in the zfill method.

'1101'.zfill(32)
# 00000000000000000000000000001101

'11100110'.zfill(32)
# 00000000000000000000000011100110

Zero-padding to 64-bit

For zero-padding to 64-bit, specify 64 as the argument in the zfill method.

'1101'.zfill(64)
# 0000000000000000000000000000000000000000000000000000000000001101

'11100110'.zfill(64)
# 0000000000000000000000000000000000000000000000000000000011100110
