python - 如何在 python 函数之外使用递增变量？

Question

这可能是一个愚蠢的问题；也许我的过程完全错误（如果是，请指出），但是如何在自定义函数中提取三个递增变量（c_char、c_word、c_sentence）并将其用于其他用途？

def length_finder(x):
    #variables counting character,word,sentnece  
    c_char = 0
    c_word = 1
    c_sentence = 0

    for i in x:
        if (i >= 'a' and i <= 'z') or (i >= 'A' and i <= 'Z'):
            c_char += 1
        if i == " ":
            c_word += 1
        if i == '.' or i == '!' or i == '?' :
            c_sentence += 1

length_finder(input("Enter the text you wish to analyze: "))

L = 100/c_word*c_char
S = 100/c_word*c_sentence

#formula to get readability
index = 0.0588 * L - 0.296 * S - 15.8

print("This text is suitable for grade " + str(index))

您可以return在函数中使用多个变量：

def length_finder(x):
    ...
    return (c_char, c_word, c_sentence)


(c_char, c_word, c_sentence) = length_finder('input string')
