# example 1

def varToSqFeet(var):
    return var*9
x = list(map(varToSqFeet, [100]))
print(x)

# output [900]

# example 2

varToSqFeetLamda = lambda var : 9*var
print (varToSqFeetLamda(100))

# output 900

# example 3

from functools import reduce
f = lambda a,b: a if (a>b) else b
print(reduce(f, [47,11,42,102,13]))

# output: 102

# Calculating the sum of the numbers from 1 to 100
from functools import reduce
print(reduce(lambda x, y: x+y, range(1,101)))
# output 5050
