Problems formatting a string - Python 2.7.3 -

-

i'm coming across little weirdness str.format() method , wondered if there might workaround.

here basic example of problem facing:

'something {first.alpha} {last}'.format(**{'first.alpha':'then', 'last':'else'})

i expect return:

"something else"

but instead error:

 keyerror: 'first'

i'm aware there other approaches formatting string, until approach seemed perfect fit needed.

the following example works perfectly, important 'first.alpha' key exists.

'something {first} {last}'.format(**{'first':'then', 'last':'else'})

is there way might still able use str.format() method , contain fullstops within key?

the way use named arguments in format this

>>> 'something {first_alpha} {last}'.format(first_alpha = 'then', last = 'else') 'something else'

i wouldn't use first.alpha because thinks first has attribute alpha.
