Python and C

l : int = len(columnTitle)
    for i in range(l):
        print(type(columnTitle[i]))

so in python you can not get char but need ord(str) / chr(int)

Chinese language and English language

Tone: Pitch in word

Intonation: Pitch in sentences

The faster the vocal cords vibrate, the higher the frequency, and the higher the perceived pitch. This frequency is measured in Hertz (Hz). For example, a 100 Hz sound is perceived as lower than a 200 Hz sound.

Actually Chinese language strictly follow the tone.
Usually, an English never speaks the real Chinese language. Because they don't see the Tone, at all.
But on the other hand, Chinese also don't not see the Intonation, but somehow Intonation is not such important like the Tone.
