How to write a program to convert Hexadecimal to Binary in Python or Psuedocode?

Question

Title says it all. Best answer to the best answer

Answer 1

Here's a function to turn a given hex number (1 digit) to bin:



if (number is F)

return 1111

if (number is E)

return 1110

if (number is D)

return 1101

if (number is C)

return 1100

if (number is B)

...[[~omitted for space, I think you can figure that out~]]



Now all the program has to do is



get inputNumber from user

convert leftmost hexnumber to bin.

print it



convert next left hexnumber to bin

print it



and so on....(sorry, don't know python)



edit: (assume MSB is on the left.)

Answer 2

Python Hexadecimal

Answer 3

Python apparently has a simple built-in way to do this.



import binascii



#.... get the Hexadecimal string you want to convert in a variable called hex_string

binary_string = binascii.unhexlify(hex_string)

# binary_string now stores the converted string.
