Here is the sample code in python.

Code:
output = command('who am i | awk \'{print($1)}\'')

Above command works fine. But I just dont want to use single quotes in awk statement such that i can avoid the usage of escape character \ and my command looks pretty neat.
why are external commands ('who am i' and 'awk') to get the user name?
Doesn't python provide native instrumentation to get this info?
Cannot you get the user name from the environment variable from within python?

PYTHON-CONFIG(1)					      General Commands Manual						  PYTHON-CONFIG(1)

NAME
python-config - output build options for python C/C++ extensions or embedding SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --extension-suffix ] [ --configdir ] [ --help ] DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter. OPTIONS
--cflags print the C compiler flags. --ldflags print the flags that should be passed to the linker. --includes similar to --cflags but only with -I options (path to python header files). --libs similar to --ldflags but only with -l options (used libraries). --prefix prints the prefix (base directory) under which python can be found. --exec-prefix print the prefix used for executable program directories (such as bin, sbin, etc). --extension-suffix print suffix used for extension modules (including the _d modified for debug builds). --configdir prints the path to the configuration directory under which the Makefile, etc. can be found). --help print the usage message. EXAMPLES
To build the singe-file c program prog against the python library, use gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp The same in a makefile: CFLAGS+=$(shell python-config --cflags) LDFLAGS+=$(shell python-config --ldflags) all: progr To build a dynamically loadable python module, use gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so SEE ALSO
