Can shell execute python?

Can shell execute python?

Actual case: shell calls python script and passes parameters to python script

In shell:

python test.py $para1 $para2

In python:

import sys
def main($canshu1, $canshu2)
  .....
main(sys.argv[1], sys.argv[2])

Use shell to call functions in python:

The python script is as follows, test.py :

import ConfigParser  
  
config = ConfigParser.ConfigParser()  
config.read("test.conf")  
  
def get_foo():  
    return config.get("locations", "foo")  
  
def get_bar():  
    return config.get("locations", "bar")

I want to call get_foo inside through the shell. I only need to execute a calling command line in the shell:

python -c 'import test; print test.get_foo()'

The -c option just tells python to execute some python command.

To store the result in a variable, you can thus do:

RESULT_FOO=`python -c 'import test; print test.get_foo()'`

Or, equivalently:

RESULT=$(python -c 'import test; print test.get_foo()')

We can also call all methods at once, putting In a collection, call the cutting method to get the corresponding value:

ALL_RESULTS=$(python -c 'import test; print test.get_foo(), test.get_bar()')

If you need the second result, put it into RESULT_BAR:

 RESULT_BAR=$(echo $ALL_RESULTS | cut -d' ' -f2)
