python float to in int conversion

Question

I have an issue that really drives me mad. Normally doing int(20.0) would result in 20. So far so good. But:

levels = [int(gex_dict         


        

Answer 1

'20.0' is a string, not a float; you can tell by the single-quotes in the error message. You can get an int out of it by first parsing it with float, then truncating it with int:

>>> int(float('20.0'))
20

(Though maybe you'd want to store floats instead of strings in your dictionary, since that is what you seem to be expecting.)
