Print in terminal with colors using python but also want to save output in file but getting unreadable text

Question

I tried terminal color code using python. But I also want to save it in a file but when I tried to that file is having unreadable text. How can I do this both?

BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE = range(8)
def cprint(text, color=WHITE):
    seq = "\x1b[1;%dm" % (30+color) + text + "\x1b[0m"
    sys.stdout.write(seq)

cprint("String", RED)

It will get a red color output in the terminal. But when I save it into a file it got with color code.

Output in the file:

 ^[[1;31mstring^[[0m

In this case when you're printing on console then only apply color codes while writing in file only include string/text you want to log. — Mahesh Karia

You could append the text to a file every time you call the function

def cprint(text, file, color=WHITE):
    seq = "\x1b[1;%dm" % (30+color) + text + "\x1b[0m"
    sys.stdout.write(seq)
    with open(file, "a",) as f:
       f.write(text)

cprint("String", "/some/file", RED)
