impython is a python interpreter that accepts pipe stdin inputs and recognizes some magic commands.

# I'm Python

## What's `impython`?

`impython` is absolutely an interpreter for python based on the function `exec`. Besides, `impython` recognizes some magic commands.

## Why `impython`?

If any program is intended to call python and to get its results (either in form of returning values or making changes in OS), the most convenient method is to start a process of python and pass python commands to python interpreter via pipe. However, the way python interacts with pipe is wired. Python will NOT execute any commands until you close the stdin. But once you close the stdin, NO other commands can you write into stdin any more. 

By using `python -m impython`, now all issues are solved. Try this:

~~~ py
from subprocess import Popen, PIPE
with Popen(['python', '-m', 'impython'], stdin=PIPE) as f:
    f.stdin.write('print("hello world")'.encode())
    f.stdin.write('$exec'.encode())
    f.stdin.write('a = 1 / 0'.encode())
    f.stdin.write('$exec'.encode())
    f.stdin.write('$exit'.encode())
