# lamda is used in python to create an annoynomous function

# d holds a function that doubles a parameter
d = lambda p: p * 2

# t holds a function that triples a parameter
t = lambda p: p * 3

x = 5

# call double function 
x = d(x)

# call triple function
x = t(x)

# should be thirty at this point
print x
