Remove Non Ascii Characters From Csv File Using Python

I am trying to remove non-ascii characters from a file. I am actually trying to convert a text file which contains these characters (eg. hello§‚å½¢æˆ äº†å¯¹æ¯”ã

Solution 1:

Variable assignment is not magically transferred to the original source; you have to build up a new list of your changed rows:

import csv

txt_file = r"xxx.txt"
csv_file = r"xxx.csv"

in_txt = csv.reader(open(txt_file, "rb"), delimiter = '\t')
out_csv = csv.writer(open(csv_file, 'wb'))
out_txt = []
for row in in_txt:
    out_txt.append([
        "".join(a if ord(a) < 128 else '' for a in i)
        for i in row
    ]

out_csv.writerows(out_txt)
