Question

my python will not run a program. it will always think that the heading is a syntax error. What can i do?

Answer 1

code please.

Answer 2

i didnt even write any code. all i entered as a test was print ('hello world') which return the syntax error and when i clicked ok to see the error it highlighted the 5 in the header that said 2.5.1

Answer 3

Did you make sure you commented out your header?

Answer 4

sadly i have no idea what that means

Answer 5

Put a # before any text and that makes it a comment. Comments are used for code that you want people to read and not the computer.

Answer 6

#hello.py
# Get the user's name and print a friendly hello
name = raw_input("Please enter your name ")
print "Hello", name, "- good to see you!"

Answer 7

Don't bother with the header at first, it's only there to let the computer know which interpreter to use. Unless you have a Python3 interpreter as the default, which is unlikely, it'll just use whatever you have set up, probably Python2.6 or 7 anyway. You can always specify an interpreter at the command line.

python2 ~/scripts/myapp.py

By the way, unless you've done

from __future__ import print_function

you shouldn't add parenthesis to your print statements.



print('hello world')

means print a tuple containing one object, the string 'hello world'. It should print

('hello world')



In Python2 we just do

print 'hello world'

Note, print is a keyword in P2, but a function in P3 so

print('hello world')

in P3 does actually mean print the string 'hello world' (by calling the print function on it).
