What helped me understand Lambdas is figuring out that they're really just a
$1,000 term for a $5 concept.
A lambda is just a single-line function without a name (Unless you assign it to
one). A syntactic shortcut.
def square_plus_one(x):
return x ** 2 + 1
squared_plus_one_list = map(square_plus_one, some_list)
is equivalent to:
squared_plus_one_list = map(lambda x: x**2 + 1, some_list)
