如何定义一个可以与不同变量一起使用并在python中生成输出的函数？

Question

我曾尝试使用此函数在变量完成内创建输出，但似乎没有任何效果

punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~ '''

def puncrem(x,y):
    for char in str(x):
       if char not in punctuations:
           y = y + char
    return y 


start = "h%e*l(l&o"

finish = ""

puncrem(start,finish)

print(finish)

Answer 1

你必须使用这样的返回值：

punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~ '''

def puncrem(x):
    y = ""
    for char in str(x):
        if char not in punctuations:
            y = y + char
    return y

start = "h%e*l(l&o"
finish = puncrem(start)
print(finish)
