I am attempting to execute the code:
values = (1, 'ab', 2.7)
s.struct.Struct('I 2s f')
packed = s.pack(*values)
But I keep getting the error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
struct.error: argument for 's' must be a bytes object
Why? How do I fix this?
With Python 3, 'ab'
isn't a bytes
object, what was called a str
on Python 2, it's unicode
. You need to use:
values = (1, b'ab', 2.7)
which tells Python that 'ab'
is a byte literal. See PEP 3112 for more info.
