Python's "invalid syntax" error message comes up often, especially when you're first learning Python. What usually causes this error and how can you fix it?
Python crashed with the error TypeError: can only concatenate str (not "int") to str. Essentially Python's saying you've used + between a string and a number and it's unhappy about it. Let's talk about how to fix this issue and how to avoid it more generally.
