Lambda Functions

Lambda functions can have any number of arguments but only one expression.
The expression is evaluated and returned. Lambda functions can be used wherever function objects are required.

It is an anonymous function that can accept any number of arguments but can only have a single expression.
You can assign a lambda to a variable
You can wrap it inside a function

double = lambda x: x * 2 

# Output: 10 
print(double(5)) 

func = lambda a, b : (a ** b) 
print( func( float(10), 20) )      #= 1E+20
