Bin to dec to hex in Python 3

You can find here how to convert between bin, dec, hex values in Python3. Python is an interpreted, object oriented and general purpose programming language. Object oriented approach helps programmers write clear, logical code for small or large projects. Python is dynamically typed and garbage collected. For converting from bin to dec to hex in Python you can use build in functions like int, format, hex or bin.

Bin to Dec in Python 3

Function int(x, base=2)returns an integer object constructed from a number or string x with the base 2. [reference]

Example

How to convert value 11111111 in bin to dec in Python.

>>> int('11111111', 2)
Output: 255

Dec to Bin in Python 3

Function format(value[, format_spec]) converts a value to a “formatted” representation, as controlled by format_spec. [reference]

Example

How to convert value 5 in dec to bin in Python.

>>> format(5, "b")
Output: 101

Bin to Hex in Python 3

Function hex(x) converts an integer number to a lowercase hexadecimal string prefixed with “0x”. If x is not a Python int object, it has to define an __index__() method that returns an integer. [reference]

Example

How to convert value 101011 in bin to hex in Python.

>>> hex(int('101011', 2))
Output: '0x2b'

Hex to Bin in Python 3

Function bin(x) converts an integer number to a binary string prefixed with “0b”. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer. [reference]

Example

How to convert value 3ef in hex to bin in Python.

>>> bin(int("3ef", 16))
Output: '0b1111101111'

Dec to Hex in Python 3

Function hex(x) converts an integer number to a lowercase hexadecimal string prefixed with “0x”. If x is not a Python int object, it has to define an __index__() method that returns an integer. [reference]

Example 1

How to convert value 185 in dec to hex in Python.

>>> hex(185)
Output: '0xb9'

Example 2

How to convert value 185 in dec to hex in Python without 0x.

>>> format(185, 'x')
Output: 'b9'

Hex to Dec in Python 3

Function int(x, base=16)returns an integer object constructed from a number or string x with the base 16. [reference]

Example

How to convert value 3ef in hex to dec in Python.

>>> int("3ef", 16)
Output: 1007
