String formatting [str.format()] with a dictionary key which is a str() of a number

Question

Python neophyte here. I was wondering if someone could help with the KeyError I am getting when using a dictionary for string interpolation in str.format.

Answer 1

You're right - the parser isn't that complex, and can't handle variable subscripts for dictionaries. Your work around is:

string2 = 'Interpolating {somevar}'.format(whateverhere..., somevar=dictionary['1'])
