![For all WWPD questions, type Function if you believe the answer is <function...>, Error if it errors, and
Nothing if nothing is displayed. As a reminder, the following two lines of code will not display anything in the Python
interpreter when executed:
>>> x = None
>>> X
>>> lambda x: x #A lambda expression with one parameter x
>>> a = lambda x: x # Assigning the lambda function to the name a
>>> a (5)
>>> (lambda: 3) () # Using a lambda expression as an operator in a call exp.
>>> b = lambda x: lambda: x # Lambdas can return other lambdas!
>>> c= b (88)
>>> C
>>> c()
>>> d= Lambda f: f(4) # They can have functions as arguments as well.
>>> def square(x):
return x * X
>>> d (square)
>>> Z = 3
>>> e = Lambda x: lambda y: lambda: x
>>>e (0) (1) ()
>>> f = Lambda z: x + Z
>>> f (3)
>>> higher_order_lambda = Lambda f: Lambda x: f(x)
>>> g = Lambda x: x* x
>>> higher_order_lambda (2) (g) # Which argument belongs to which function call?
>>> higher_order_lambda (g) (2)
+ Z
>>> call_thrice = lambda f: lambda x: f(f(f(x)))
>>> call_thrice (lambda y: y + 1) (0)
