Question

I am trying to translate code from php to python. I have a list of binary literals –

['0b0', '0b0', '0b0', '0b0', '0b0', '0b0', '0b100', '0b1001100']

This is equal to 0000000000000000000000000000000000000000000000000000010001001100 when concatenated.

int("0000000000000000000000000000000000000000000000000000010001001100",2)

gives 1100

How do i make this from the list. Unable to concatenate binary literals.

Answer 1

>>> l = ['0b0', '0b0', '0b0', '0b0', '0b0', '0b0', '0b100', '0b1001100']
>>> int("".join("%02x" % int(x,0) for x in l), 16)
1100

Python understand 0b0101 as a binary literal, so I use int('0b0101', 0) to convert each piece to an int. Then I format it in a convenient format (two digits of hex), concatenate them, and interpret them as a hex integer.
