python - 如何在某个字符后停止读取输入？

Question

我打算在“!”之后停止读取输入。出现。这是我的代码的一部分:

msg = input("What is your message? ")

print()

lett = 0
otherch = 0
num_vowels = 0
num_consanants = 0

count_character = [0] * 100000

for character in msg.upper():
    if character == "!":
        print("lett =", lett)
        print("other char = ", otherch)
        print("num_vowels = ", num_vowels)
        print("num_consanants = ", num_consanants)
    elif character < "A" or character > "Z":
        otherch = otherch + 1
        count_character[ord(character)] = count_character[ord(character)] + 1
    else:
        lett = lett + 1
        count_character[ord(character)] = count_character[ord(character)] + 1
for character in msg.upper():
        print("character", character, "appeared" , count_character[ord(character)] , "times")

但是，如果我运行程序并输入诸如“hello!hi”之类的内容，它会继续读取感叹号后的文本，并继续说输入中有两个 H 和一个 I。有 helper 吗？

在 if character == "!": block 内使用 break。它跳出 for character in msg.upper(): 循环。
