The behaviour is correct, it's your assumptions that aren't :)
The code for str.format only checks for what's before the colon (here, "HGNC") and checks if that's part of the dict provided. It isn't, so it raises a KeyError. It doesn't even get to the format spec part (which is a perfectly valid format specifier). Your dict can contain anything or be empty, str.format only checks for the existence of the key you asked for ("HGNC"). "{HGNC:11892}" is also a perfectly valid Python string.
P.S.: While I'm fine with people calling me by my last name, there's another developer whose name is Barry Warsaw, so let's try to avoid confusion here ;-) |
