SyntaxError: Missing parentheses in call to 'print'

Question

I've been trying to scrape some twitter's data, but when ever I run this code I get the error SyntaxError: Missing parentheses in call to 'print'.

Can someone please help me out with this one?

Thanks for your time :)

Answer 1

It seems like you are using python 3.x, however the code you are running here is python 2.x code. Two ways to solve this:

• Download python 2.x on Python's website and use it to run your script
• Add parentheses around your print call at the end by replacing print r by print(r) at the end (and keep using python 3)

But today, a growing majority of python programmers are using python 3, and the official python wiki states the following:

Python 2.x is legacy, Python 3.x is the present and future of the language

If I were you, I'd go with the second option and keep using python 3.

Answer 2

Looks like you trying to run Python 2 code in Python 3, where print is function and required parentheses:

print(foo)

Answer 3

Within python 2, print has been a statement, not a function. That means you can use it without parentheses. In python 3, that has changed. It is a function there and you need to use print(foo) instead of print foo.

Answer 4

You just need to add pranethesis to your print statmetnt to convert it to a function, like the error says:

print expression -> print(expression)

In Python 2, print is a statement, but in Python 3, print is a function. So you could alternatively just run your code with Python 2. print(expression) is backwards compatible with Python 2.

Also, why are you capitalizing all your comments? It's annoying. Your code also violates PEP 8 in several ways. Get an editor like PyCharm (it's free) that can automatically detect errors like this.

• You didn't leave a space between # and your comment
• You didn't leave spaces between = and other tokens
