SyntaxError: EOL while scanning string literal on with open() statement

[Regulus]

Hi! I am getting this error message in Python 3.6.3, using Spyder 3.2 in Anaconda 5.0.1 on Windows 7.
^
SyntaxError: EOL while scanning string literal
The interpreter is pointing to the colon at the end of the first line...

with open ("hello.txt', 'w') as f:
    f.write('writing over hello world')

This docs page says in section 7.2 that is how it's supposed to be written in Python 3. Python 3 Documentation

What is wrong with the code here? Thank you..

you open with " but never close it

with open ("hello.txt', 'w') as f:

should be:

with open ("hello.txt", 'w') as f:

Ah, thank you! Just needed to increase the font size in Spyder with Ctrl+.

No, you just needed to close the string you started. :P
