Python Error Messages: Gotta Catch ‘em All
New and experienced programmers constantly cause errors. The error messages are often terse, so do a
web search of the message to find out what it means. If you get an error message like
ModuleNotFoundError: No module named 'my_module_name', try doing a web search for the generic
parts of the message like "ModuleNotFoundError: No module named" instead of “my_module_name”.
For each error you encounter:
1. Check off these error messages below if you haven’t seen it before.
2. Write down the line of code that caused it (this is given towards the bottom of the error
message).
3. Do a web search of the error message to find out common causes of the error.
4. Write down the code change that fixed the error and/or a short description.
Example:
✓
IndexError: string index out of range
'hello'[99]
'hello'[4] I made the index between 0 and 4.
IndexError: string index out of range
KeyError: 'some_text_here'
ModuleNotFoundError: No module named 'some_text_here'
NameError: name 'some_text_here' is not defined
SyntaxError: can't assign to literal
