How to convert "str" to "int"

[colt]

I don't know why, but now the code is working on python 3.2, since it converts the values to int.

That's because in python 3 a bytes string is a sequence of small integers:

>>> # python 3
>>> x = b'\x02'
>>> x[0]
2

in python 2

>>> # python 2
>>> x = '\x02'
>>> x[0]
'\x02'

In python 2 you can convert a one character string to int by using the ord function

>>> ord(x[0])
2

But when calling struct.unpack ("I", self.temp), make sure self.temp is a 4 bytes string.

Finally, do you have to use python 2? Don't use it, it's dead.

Tried

self.num_prg_blocks = ord (self.header [4])

and it solved this issue with old python, but with the new python I receive:

TypeError: ord() expected string of length 1, but int found

To answer, I do not HAVE to use it, as mandatory
