Lambda expression which takes a tuple (a, b[], c) and return tuples flattening list b e.g. (a, b[0], c), (a, b[1], c)

Hi there I am trying to construct a lambda expression which takes in tuples of the form:
(a, b[], c). Where b is a list of elements which needs to be flattened.

for example the output of the expression should be:
(a, b[0], c), (a, b[1], c), (a, b[2], c) …

I’ve tried researching and looking for generator expressions examples for this context everywhere but cant really wrap my head around this.

I would appreciate it if someone could point me in the right direction.

>Solution :

You can use itertools.repeat() with zip() to create the desired tuple for each element in b:

from itertools import repeat

f = lambda a, b, c: zip(repeat(a), b, repeat(c))

print(*f(1, [2, 3, 4], 5))

This outputs:

(1, 2, 5) (1, 3, 5) (1, 4, 5)
