How to execute a single line of a python script in Terminal? -

i have current simple script saved ex1.py in sublime text 2 ide.

print "hello world!" print "hello again" print "i typing this." print "this fun." print 'yay! printing.' print "i'd rather 'not'." print 'i "said" not touch this.' 

i execute single line script in terminal, haven't been able figure out how.

the script executes 7 lines. there way specify, example, want execute line 3?

as @wooble says, odd requirement, anyway, here solution in bash session:

use awk extract line want (e.g. line 2):

$ awk 'nr==2' ex1.py  print "hello again" 

then feed python interpreter through stdin.

$ awk 'nr==2' ex1.py  | python hello again 

you can specify range

$ awk 'nr>=2 && nr<=4' ex1.py  | python hello again typing this. fun. 

edit: note in case, equivalent sed command requires fewer keystrokes

$ sed -n '2,4 p' ex1.py  | python hello again typing this. fun.
