Problem with Generator

[palladium]

Thanks for the tip.

I tried the following and it works. Hopefully there's no redundant stuff here:

file_name = "techcruncher.csv"
lines = (line for line in open(file_name))
list_line = (s.rstrip().split(",") for s in lines)
cols = next(list_line)
company_dicts = (dict(zip(cols,data)) for data in list_line)
z = list(company_dicts)
funding = (
        int(item["raisedAmt"])
        for item in z
        if item["round"] == 'a')
x = list(funding)
print(sum(x)/len(x))
