#lambda n : n in this case is the passed valuelambda function in python
Lamda is just one line anonymous function
Useful when writing function inside function
it can take multiple arguments but computes only one expression
Syntax:
x = lambda arguments : expressionpython3 lambda
>>> sum = lambda x, y : x + y
>>> sum(3,4)
