I agree. Lamdas are no big deal once you get past some obfuscation
and understand they perform a very simple function. Of course, both
of us could be missing something important. There is a lot of deep
theory behind the lambda calculus. While drawing a tentative
conclusion, we have to always keep an open mind to something new.

This is an impressive body of knowledge, but unless I see how it is
going to help me write some code, I won't have time to study it. My
understanding of lambda functions is simply that they are a way to
squeeze functions into a tight space:
list_of_funcs = [(lambda x: 2**x), (lambda x: 3**x), (lambda x: 4**x)]
If you are not concerned about space, simply use normal defs:
def f2(x): return 2**x
def f3(x): return 3**x
def f4(x): return 4**x
list_of_funcs = [f2, f3, f4]
Is there any other reason in Python to use lambdas?
