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

I think what you are looking for is:

dictionary = {'key1': 'val1', '1': 'val2'}
string2 = 'Interpolating {key1}'.format(**dictionary)
print string2
