Examine for nulls, empty strings, and proper sorts
In a later weblog put up I could clarify how I added sort checking to Python, however this error message which isn’t precisely exact is attributable to a lacking worth in my case.
I’m writing a parser that reads directions from a file. When it hits an instruction it parses out the motion to take and associated attributes that point out what knowledge the motion ought to act upon.
In my configuration, I mistyped the attributes for my motion. That brought about a worth of None to be handed in the place a operate anticipated a unique sort to be handed into it.
Added sort checking to the values I used to be passing into the operate previous to taking the motion and acquired an error that one among my handed in values was incorrect.
I’m undecided what iterable has to do with it for the reason that lacking worth was a string. Iterable means one thing you possibly can loop by means of. At any price, I fastened the configuration to appropriately cross within the lacking worth and resolved the error.
