有没有办法让这段代码不那么长，但做同样的事情？

Question

sentence = input("What is your sentence?")
sentence=sentence.capitalize()
counta = sentence.count("a")
counte = sentence.count("e")
counti = sentence.count("i")
counto= sentence.count ("o")
countu= sentence.count ("u")
countA2 = sentence.count("A")
countE2 = sentence.count("E")
countI2 = sentence.count("I")
countO2 = sentence.count("O")
countU2 = sentence.count("U")
countI3 = sentence.count(" I ")
countspaces = sentence.count(" ")
a1 = sentence.count("!")
a2 = sentence.count(".")
a3 = sentence.count(">")
a4 = sentence.count("<")
a5 = sentence.count(":")
a6= sentence.count(";")
a7 = sentence.count("'")
a8 = sentence.count("@")
a9 = sentence.count("#")
a10 = sentence.count("~")
a11= sentence.count("{")
a12= sentence.count("}")
a13= sentence.count("[")
a14 = sentence.count("]")
a15 = sentence.count("-")
a16 = sentence.count("_")
a17 = sentence.count("+")
a18 = sentence.count("=")
a19 = sentence.count("£")
a20 = sentence.count("$")
a21= sentence.count("%")
a22 = sentence.count("^")
a23= sentence.count("&")
a24 = sentence.count("(")
a25= sentence.count(")")
a26=sentence.count("?")
count = (counta + counte + counti + counto + countu + countA2 + countE2 +     countI2 + countO2 + countU2 + countI3)
speci= a1+a2+a3+a4+a5+a6+a7+a8+a9+a10+a11+a12+a13+a14+a15+a16+a17+a18+a19+a20+a21+a22+a23+a24+a25+a26)
print(sentence)
print("This has", speci, "special characters")
print("This has", countspaces, "Spaces")
print("This has", count, "vowels")

您可以看到上面的代码waaayyy太长了。我不知道如何做同样的事情（这是用户输入的句子，它计数元音，空格和特殊字符），但在更少的代码行。如果你知道更好的方法。请告诉我。因为编码当然是关于最好的代码的，这看起来很奇怪，是最好的方式。 谢谢你的帮助

Answer 1

看看解决方案，你可能已经下定决心了。只需通过选择要使用的单个字符来缩短它，请尝试下面的代码。你知道吗

word = "banana"
characters = ["A", "E", "I", "O", "U"]
for letter in word:
    if letter in characters:
        print("Special character.")

当然，用我在列表中添加元音的相同方法添加更多字符。你知道吗

Answer 2

如果要检查特殊字符，请执行以下操作：

special_char = 0
for i in sentence:
    if i.isalpha() == False and i.isdigit() == False:
        special_char += 1

对于空间：

spaces = sentence.count(' ')

对于元音，制作一个以元音为键的字典，然后遍历整个输入，并与元音dict中的各个键进行匹配

Answer 3

如果您喜欢列表理解：

sentence = raw_input("What is your sentence ? ")
print "Vowels : " + str(len([i for i in sentence if i.lower() in ('a','e','i','o','u')]))
print "Spaces : " + str(sentence.count(' '))
print "Special Chars : " + str(len([i for i in sentence if (not i.isalpha() and not i.isdigit() and not i.isspace())]))
