String formatting [str.format()] with a dictionary having a key which is a str() of a number
- by decimus phostle
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.
dictionary = {'key1': 'val1', '1': 'val2'}
string1 = 'Interpolating {0[key1]}'.format(dictionary)
print string1
The above works fine and yields:
Interpolating val1
However doing the following:
dictionary = {'key1': 'val1', '1': 'val2'}
string2 = 'Interpolating {0[1]}'.format(dictionary)
print string2
results in:
Traceback (most recent call last):
File "test.py", line 3, in <module>
string2 = 'Interpolating {0[1]}'.format(dictionary)
KeyError: 1L
So the problem seems to be in the interpretation of the numeric key as a list index, IMHO. Is there any way to work around this? (i.e. convey that this is instead a dictionary key)
TIA and apologies if this question has been asked before(couldn't find anything relevant with my search-fu).
