Syntax Error on good code

The gross majority of the time a SyntaxError which points to an uninteresting line means there is an issue on the line before it (in this example, it’s a missing parenthesis):

def my_print():
    x = (1 + 1
    print(x)

Returns

File "<input>", line 3
  print(x)
      ^
SyntaxError: invalid syntax

The most common reason for this issue is mismatched parentheses/brackets, as the example shows.

There is one major caveat for print statements in Python 3:

>>> print "hello world"
 File "<stdin>", line 1
   print "hello world"
                     ^
SyntaxError: invalid syntax

Because the print statement was replaced with the print() function, so you want:

print("hello world")  # Note this is valid for both Py2 & Py3
