Using C datatypes with ctypes in python

Question

I tried to use C char pointer datatype in python 3.3. I used following code:

    from ctypes import *

    firstname = c_char_p("I am a noob programmer".encode("utf-8"))
    print(firstname.value)

My desired output was

    I am a noob programmer

but what I got was

    b'I am a noob programmer'

I am following a tutorial made for python 2.6. I used "ascii" as the parameter for encode function. And also tried the "bytes()" instead of encode. But no difference at either time.Why don't I get my desired output? and How can I get the output as desired.

Please anybody help me to understand..

The output is correct for Python 3. Use Python 2.6 if you want to see the same output as the tutorial. — Martijn Pieters

In Python 3 you need to decode it back to str if you want it to behave like str.

print(firstname.value.decode("utf-8"))
