syntax

lambda keyword followed by :

• a comma-separated list of arguments
• a colon
• a single expression that returns the value of the function.

lambda x : x # this line does not transform the input, it simply returns it as is for the sake of the example

lowercase = lambda x: x.lower()

# equivalent representation
def lowercase(x):
    return x.lower()

square = lambda x: x * x

for el in range(1, 5):
    print(square(el))

equals_lambda = lambda x, y: x == y
