Anonymous Functions

Anonymous functions in Python that  do not have a name. With the lambda keyword, little anonymous functions can be created. Anonymous functions are also called lambda functions by Python programmers. They are part of the functional paradigm incorporated in Python. Lambda functions are restricted to a single expression.

y = 6
z = lambda x: x * y
print(z(8))

This is a small example of the lambda function.

z = lambda x: x * y

The lambda keyword creates an anonymous function. The x is a parameter that is passed to the lambda function. The parameter is followed by a colon character. The code next to the colon is the expression that is executed, when the lambda function is called. The lambda function is assigned to the z variable.

cs = [-10, 0, 15, 30, 40]

ft = map(lambda t: (9.0/5)*t + 32, cs)
print(list(ft))
