How can I call a (string) method assigned to a dict value like this
dict = { True: ''.lower }
I tried
flip = True
print("A".dict[flip])
but then I get:
AttributeError: 'str' object has no attribute 'dict'

Pass the string value to the method, by calling that method: `dict[flip]("A")`. You want to store *unbound methods* however, e.g. `str.lower` instead of `''.lower`. The latter is already bound, to the empty string. – Martijn Pieters Aug 19 '22 at 18:25

d = {True: lambda x: x.lower()}
flip = True
print(d[flip]('A'))
prints
a

3@NilsLindenberg: use `str.lower` to get the unbound string method. – Martijn Pieters Aug 19 '22 at 18:26
