choice = "lillian"
firstpick = "l"
for n in choice:
if n != firstpick:
inverse = n
if inverse in choice:
print(choice.replace(inverse,'-'))
這段代碼的期望輸出應該是“l-ll---”但它是“l-ll-an”“l-ll-an”“lilli-n”“lillia-”
對此很抱歉，我不是最擅長代碼的，但我很感激一個解決方案。謝謝！

這是一種選擇：
choice = "lillian"
firstpick = "l"
''.join([c if c==firstpick else '-' for c in choice])

字串是不可變的，因此您需要存盤替換的結果。試試這個：
choice = "lillian"
firstpick = "l"
for letter in choice:
if letter != firstpick:
choice = choice.replace(letter, '-')
print(choice)
