Simple Average

[ddoogles]

Not homework.  Wish I was back in school.  I have a New Years resolution to learn Python and use it at work whenever I can.  I deal with very large data sets and often the records exceed the 1M mark to use in Excel.  Any suggestions would be appreciated.
  
Here is the code I wrote.  Yes it's poor I know.

f = open("pricelist.txt", "r")

SSPList = {}

for line in f:
    entry = line.strip().split(",")
    PartNo = entry[0]
    Price = entry[1]
    AvgPrice = sum(Price)/len(SSPlist)
f.close()

print(SSPList)


and here is my error message:

Traceback (most recent call last):
  File "C:/Python34/Scripts/SSPTest.py", line 8, in <module>
    Price = entry[1]
IndexError: list index out of range

---

Ok, so I messed with it a little more, but I struggle with how to calculate the average.  Here is my new code and error message:

f = open("pricelist.csv", "r")

SSPList = {}

for line in f:
    entry = line.strip().split(",")
    PartNo = entry[0]
    print(PartNo)
    Price = entry[1]
    print(Price)
    AvgPrice = sum(Price)/len(SSPlist)
    SSPList[PartNo] = AvgPrice

f.close()

print(SSPList)



Error message:
