Writing an Integer Variable

To write integers (not strings) of hex, octal, binary into Python, or convert back to decimal, precede each integer with 0x… , 0o… or 0b… respectively or use a function.

Convert a decimal to another base:

  • … Decimal, no modification needed just write the numbers without quotes (Default)
  • oct(…) Octal
  • bin(…) Binary
  • hex(…) Hex
  • int(integer, base)Write an integer of any base

Write a number of another base directly:

  • 0o… Octal
  • 0b… Binary
  • 0x… Hex

You will often see hex numbers represented in this way.

Writing an integer into a string

If you want to write these into a string you need to use an f-string, i.e. f"{0b...}" as they are implicitly of integer type.

Writing Byte Values Inside a String

The following to escape sequences are ways of representing the decimal an integer hex in or oct as bytes, inside a string:

\x▯▯ Where ▯▯ is a hexadecimal number up to ff

Note that \▯▯▯, where ▯▯▯ is an octal number, is a way to write a unicode character, not an octal number, into a string (there really is no \o.\o, its just \). It is just the octal version of \u#### orU########.
