CS50 IDE Debugging

Text Editor Debugging

Once you've saved a file with a file extension (i.e. something.py), CS50 IDE's text editor will detect syntax errors in your code. Sometimes the error will be on the same line asand other times it will be the line after. Keep this in mind when you're debugging your code.

Example 1

Cloud9 detects a syntax error on the same line as the syntax error.

Example 2

Cloud9 detects a syntax error as the line after the syntax error.

Terminal Debugging

Similarly, if run the file in the Terminal, Python will give you a similar error message. Remember, the error is on that line or the previous line.
