Re: gett error message: "TypeError: 'int' object is not callable"

Hi Rhodri, It's only really a pitfall if you try to use the built-in after you've redefined it. That's the thing to keep an eye open for. You're right, but in cases where you're editing a codebase which you didn't author entirely by yourself you may not be aware of that. That said, if the

Hi, Do you know a good way to avoid running into this problem? It makes sense to suggest not calling variables the same names as built-in functions, but that's hard for a new python programmer who doesn't already know what all the built-in functions are. Over time a programmer will learn which

Re: gett error message: "TypeError: 'int' object is not callable"

Look at: len = len(text) You're overriding `len` (a built-in method), with an integer (`len(text)`). You then call: for i in range(len(fields)): But `len` is no longer a callable, but merely an integer. Regards, Friðrik Már P.S. While this is a fairly obvious problem it's usually a g
