I tried the PythonTeX package, and the output it produced contained question marks instead of running python code, what should i do ??

This is a bug in the console environments. The current working directory isn't being added to sys.path. I will fix this in the next release.
If you're using PythonTeX v0.12beta (on GitHub) you can use the following workaround for now.
\documentclass[11pt]{article}
\usepackage[makestderr]{pythontex}
\begin{document}
\begin{pyconcode}
import os
import sys
sys.path.append(os.getcwd())
\end{pyconcode}
\begin{pyconsole}
import sayhi
sayhi.hi()
\end{pyconsole}
\end{document}
\py doesn't accept this, but only an explicit number. Here's a possibly working version, where the dimension is expanded to a number before passing it to \py:
\documentclass{scrreprt}
\usepackage{pythontex}
\makeatletter
\newcommand{\printlength}[1]{%
\begingroup\edef\x{\endgroup
\noexpand\py{printtexlength(\strip@pt\dimexpr#1\relax)}}\x}
\makeatother
\begin{document}
\begin{pycode}
def printtexlength(length):
print('Length is %f' % length)
\end{pycode}
\printlength{\textwidth}
\printlength{1in}
\end{document}
I don't know enough Python to understand why None appears.
Thanks to G. Poore, here's the correct version of the function:
\begin{pycode}
def printtexlength(length):
return 'Length is %f' % length
\end{pycode}

Packages which call other programs, such as
sagetex,python,gnuplot, or (as G. Poore confirms)PythonTeXrequire you to process the your document in a similar fashion: 1. (pdf)latex your document to create a special file (withsagetexit's a .sage file. 2. Process the special file with the program/script (Sage/Python/gnuplot) 3. (pdf)latex your document again.After step 1 your output will have ?? marks where the computations/pictures are supposed to be. I suspect you didn't realize that 2 more steps of processing are necessary. As G. Poore indicates above your second step will be "run the PythonTeX script (pythontex2.py or pythontex3.py, depending on your Python version)". Depending on the package you might be able to streamline the process with a shell escape in your tex file or configuration of your IDE
