How to write a iadx or text file with BOM in python

Question

I want to use BOM with UTF-8. But it only saves files in UTF-8. What can I do ?I'm rather new, could you please write an answer as an addition to the sample code I shared directly?

import os
import codecs
a=1

filelist=os.listdir("name")
for file in filelist:
    filelen=len(os.listdir("name/"+file))
    if filelen==10:
        with open(file + ".iadx", "w", encoding="UTF-8") as f:
            f.write("<name>")
            f.write("\n")
            f.write('something')

Why do you need a BOM in UTF-8? It's not required or recommended. — Progman, Dec 18 '22 at 21:38

From Python documentation on codecs (search for "-sig") :

On encoding the utf-8-sig codec will write 0xef, 0xbb, 0xbf as the first three bytes to the file.

So just doing :

with open(file + ".iadx", "w", encoding="utf-8-sig") as f:
#                                             ^^^^

will do the trick.
