[PYTHON] Character code conversion of CSV file using Loop (Shift JIS to UTF8)

Suppose you have a CVS file with consecutive filenames like this:

• brabra_01.csv
• brabra_02.csv
• brabra_03.csv
• (...)
• brabra_47.csv

The character code of the original file is Shift-JIS, and these are converted to UTF-8 at once. Furthermore, the serial numbers of the files are eliminated from zero padding and renamed as follows:

• brabra_1_utf.csv
• brabra_2_utf.csv
• brabra_3_utf.csv
• (...)
• brabra_47_utf.csv

The code is as follows.

import csv
import codecs
a = 47
for i in range(a):
    pref = i + 1
    path = "c:/*****/brabra_%02.f.csv"%pref
    path_utf = "C:/****/brabra_%01.f_utf.csv"%pref
    fin = codecs.open(path, "r", "shift_jis")

    fout_utf = codecs.open(path_utf, "w", "utf-8")
    
    for row in fin:
        fout_utf.write(row)
        
    fin.close()
    fout_utf.close()
