def getNthCharacter(string, n): if n > len(string): return ""; return string[n-1];
Iyi kodhi inotsanangura basa rinotora nharo mbiri, tambo uye nhamba. Kana nhamba yacho yakakura kudarika urefu hwetambo, inodzorera tambo isina chinhu. Zvikasadaro, inodzosa chimiro mutambo pane index inotsanangurwa nenhamba.
Chii chinonzi nth character
The nth character muPython ndiye munhu ari panzvimbo n mutambo.
