What the last line for?


#1

def spam():
eggs = 12
return eggs

print spam()

Checked the code above in http://pythontutor.com/visualize.html#mode=edit
but it shows that SyntaxError: invalid syntax (, line 5)
why? What's the spam() for?


#2

In a Python 3 environment, print is a function so must take an argument.

print (spam())

This code will also work in Python 2 so if you feel like getting practice with Python 3 syntax, feel free. In most cases the SCT should be ignoring it, so only becomes a problem if the code is being pattern matched.
