Decimal to Hexadecimal



In [1]:

    
dec_num = 254
print('{:X}'.format(dec_num))

FE

Note that I have used the format() function here together with the {:X} placeholder which tells Python to print the number as Hexadecimal.

There is a hex() function available but it prepends the output with "0x" which may be a nuisance for what you are doing.

HexHexadecimal to Decimal



In [2]:

    
hex_string = 'FE'
print(int(hex_string, 16))

Note the use of ", 16" in the int() function? That tells python that we are converting from a Hex string as opposed to an integer string.
