trying to calculate the total overall weight of available items in my dictionary's not sure how-CodePudding

weight = {"pencil" : "10", "pen" : "20", "paper" : "4", "eraser" : "80" }

available = {"pen" : "3", "pencil" : "5", "eraser" : "2", "paper" : "10"}

overall_weight = 0

for key, value in weight.items():

if key in available:
    overall_weight = weight.values() * available.values()
    print (overall_weight)

print("Overall weight:", overall_weight)

CodePudding user response：

You need to cast the values to int. This should work:

weight = {"pencil" : "10", "pen" : "20", "paper" : "4", "eraser" : "80" }
available = {"pen" : "3", "pencil" : "5", "eraser" : "2", "paper" : "10"}

overall_weight = 0

for key, value in weight.items():
    if key in available:
        currA = int(value)
        overall_weight  = int(available[key]) * int(value)
        print (overall_weight)

print("Overall weight:", overall_weight)
