Answer 1

Would something like this work for you?

parts = line.split("t")
result = parts[0] + "," + parts[2]

If you want to keep the tabs then the last line becomes:

result = parts[0] + "t,t" + parts[2]

Answer 2

You could match 1+ non whitespace chars between 2 tabs, and in the replacement use a comma between 2 tabs.

pattern = r"tS+t"

s = ("[f34  382 5.00]n"
            "[f35   42  3.70]n"
            "[f36   72  1.09]n"
            "[f37   588 8.56]n"
            "[f38   2837    7.82]")

print(re.sub(pattern, "t,t", s))

Output

[f34    ,       5.00]
[f35    ,       3.70]
[f36    ,       1.09]
[f37    ,       8.56]
[f38    ,       7.82]
