Question

Complete the following function in python based on the cutomers request.

Function:

def hydrocarbon(hydrogen,carbon,oxygen):

#Add your code here

Customer Request:

take in three parameters assumed to be hydrogen, carbon, and oxygen IN THAT ORDER.

validate that all three values are non-negative integers:

if not than you should return None

if all three parameters are valid then you should calculate the mass of the hydrocarbon and return the mass where:

Each hydrogen has a molecular weight of 1.0079

Each carbon has a molecular weight of 12.011

Each oxygen has a molecular weight of 15.9994

For example:

hydrocarbon(4,3,0) will return 40.0646

hydrocarbon(1,2,3) will return 73.0281

hydrocarbon(-1,-1,-1) will return None

Answer 1

def hydrocarbon(hydrogen,carbon,oxygen):
if hydrogen < 0 or carbon < 0 or oxygen < 0:
return None
else:
return hydrogen * 1.0079 + carbon * 12.011 + oxygen * 15.9994
  

print(hydrocarbon(4,3,0))
print(hydrocarbon(1,2,3))
print(hydrocarbon(-1 , -1, -1))

Output:

$python3 main.py
40.0646
73.0281
None

ef hydrocarbon(hydrogen, carbon, oxygen): if hydrogeneor carbon<e or oxygen: python3 main.py 18.0646 73.0281 None return None else return hydrogen 1.0079+carbon 12.011 + oxygen 15.9994 print (hydrocarbon(4,3,0)) rint (hydrocarbon(1,2,3)) (hydrocarbon(-1, -1, -1))
