why do i get error "can't multiply sequence by non-int of type 'float'"?
def nestEgVariable(salary, save, growthRates):
SavingsRecord = []
fund = 0
depositPerYear = salary * save * 0.01
for i in growthRates:
fund = fund * (1 + 0.01 * growthRates) + depositPerYear
SavingsRecord += [fund,]
return SavingsRecord
print nestEgVariable(10000,10,[3,4,5,0,3])
thanks Baba
for i in growthRates:
fund = fund * (1 + 0.01 * growthRates) + depositPerYear
should be:
for i in growthRates:
fund = fund * (1 + 0.01 * i) + depositPerYear
You are multiplying 0.01 with the growthRates list object. Multiplying a list by an integer is valid (it's overloaded syntactic sugar that allows you to create an extended a list with copies of its element references).
Example:
>>> 2 * [1,2]
[1, 2, 1, 2]
