Python: Ternary operator syntax error

Question

I am trying to use a ternary condition in my program as follows:

c = 12
(print c) if (c == 10) else (print 'c is not 10')

However, this raises a syntax error. What seems to be wrong here?

You can only have expressions, not statements, in a ternary expression. — jonrsharpe

BTW, in Python 3 the following works: c = 12 ; (print (c)) if (c == 10) else (print ('c is not 10')) — boardrider

You would do it like this:

print c if c == 10 else 'c is not 10'

The parenthesis are unnecessary, and you must start with the "print"; Python cannot make the whole command a conditional the way Perl can.

There is no Python equivalent of Perl's:

print "Done!" if $done;

The quote was always supposed to be there. Edited my code in the original post.

you shall do print(c) instead of (print c)

c = 12 print(c) if (c==10) else print('not c') still gives syntax error. Its not about parenthesis as Will mentioned in his answer.
