How to execute Python inline from a bash shell

This works:

python -c 'print("Hi")'Hi

From the manual, man python:

   -c command          Specify  the command to execute (see next section).  This termi-          nates the option list (following options are passed as arguments          to the command).

python shell inline execution

Another way is to you use bash redirection:

python <<< 'print "Hi"'

And this works also with perl, ruby, and what not.

p.s.

To save quote ' and " for python code, we can build the block with EOF

c=`cat <<EOFprint(122)EOF`python -c "$c"

python shell inline execution

A 'heredoc' can be used to directly feed a script into the python interpreter:

python <<HEREDOCimport sysfor p in sys.path:  print(p)HEREDOC/usr/lib64/python36.zip/usr/lib64/python3.6/usr/lib64/python3.6/lib-dynload/home/username/.local/lib/python3.6/site-packages/usr/local/lib/python3.6/site-packages/usr/lib64/python3.6/site-packages/usr/lib/python3.6/site-packages
