How to read numbers in python from csv file?

Question

I have a csv file and I have to compute the mean for some of the columns. That\'s how I did:

file=csv.reader(open(\'tab.csv\',\'r\'))
n=[]
for row in file:
          


        

Answer 1

Just add quoting:

with open('tab.csv', newline='') as file:
    reader = csv.reader(file, quoting=csv.QUOTE_NONNUMERIC)
    n=[]
    for row in reader:
        n.append(row[8])
