Reading and writing a csv file Python

Question

I just started learning Python, and I am trying to do the following: - Read a .csv file - Write the filtered data in a new file where the column 7 is not blank/empty

When I am printing my results, it shows the right output in the python shelf, but when I am checking my data in the .csv is no correct (differs from what is showing with the print function) Any suggestion with my code?

Thank you in advance.

file = open("station.csv", "r")
writeFile = open("stations-filtered.csv", "w")

for line in file:
    line2 = line.split(",")
    if line2[7] != "":
        print(line)
        writeFile.write(line)

I agree with @user513093 that you can use csv , like:

file = open("station.csv", "r")
writeFile = open("stations-filtered.csv", "w")
writer = csv.writer(writeFile, delimiter=',')

for line in file:
    line2 = line.split(",")
    if line2[7] != "":
        print(line)
        writer.writerow(line)

But still, pandas is good:

import pandas as pd
file = pd.read_csv("station.csv", sep=",", header=None)
file = file[file[7] != ""]
file.to_csv("stations-filtered.csv")
