如何替换输入字符串中的()输入字符

Question

我的程序的目的是要求用户输入一个句子，然后要求用户输入他们希望从字符串中删除的任意数量的字符。该程序只替换最后一个要输入的字符，而不是全部替换

请记住，我在这方面还相当陌生：(

print("Please enter a sentence")

sentence = input()

print("Please type the  characters you would like to make dissapear!!! ")

while True:
repchar = input()
for i in repchar:

i = sentence.replace(repchar , "")
if repchar == "":
print(i)
break

Answer 1

这是一个小错误。您需要对整个句子进行更改，但由于i在每次迭代中都会发生更改，因此从未存储替换的句子。

print("Please enter a sentence")
sentence = input()
print("Please type the  characters you would like to make dissapear!!! ")
while True:
repchar = input()
for i in repchar:

sentence = sentence.replace(repchar , "") # here you were replacing the 
# character but storing it in i 
# that changes every iteration
if repchar == "":
print(sentence) # Printing the sentence not just i
break
