Exercise 01.1 - Solution

Create a function that receives two inputs a and b, and returns the product of the a decimal of pi and the b decimal of pi.

i.e, 
pi = 3.14159
if a = 2 and b = 4
result = 4 * 5
result = 20

Caveats:

a and b are between 1 and 15
decimals positions 1 and 2 are 1 and 4, respectively. (remember that python start indexing in 0)

Crear una funcion que recibe dos parametros a y b. Y evalua la multiplicacion del a decimal de pi y el b decimal de pi.

    # Get pi decimals
    pi_dec = str(pi)[2:]
    
    return float(pi_dec[a-1]) * float(pi_dec[b-1])

    Out[2]:





20.0



In [3]:

    
mult_dec_pi(a=5, b=10)
# 45.0









    Out[3]:





45.0



In [4]:

    
mult_dec_pi(a=14, b=1)
# 9.0









    Out[4]:





9.0



In [5]:

    
mult_dec_pi(a=6, b=8)
# 10.0









    Out[5]:





10.0



In [6]:

    
# Bonus
mult_dec_pi(a=16, b=4)
# 'Error'









    Out[6]:





'Error a or b are out of the expected ranges'
