Python 在另一个函数中调用函数
我试图在word_counter函数中调用clean函数,但我不知道怎么做 这个程序的工作原理是一个字符串通过cleanse函数,该字符串中所有被删除的字符都被删除,然后被小写。从那里,我需要在word_计数器中“调用”已清除的消息,但这就是我被卡住的地方。我在下面试过了Python 在另一个函数中调用函数,python,string,function,call,message,Python,String,Function,Call,Message,我试图在word_counter函数中调用clean函数,但我不知道怎么做 这个程序的工作原理是一个字符串通过cleanse函数,该字符串中所有被删除的字符都被删除,然后被小写。从那里,我需要在word_计数器中“调用”已清除的消息,但这就是我被卡住的地方。我在下面试过了 #how to call this function? def cleanse(message): cleansed_message = '' remove_characters = "+-=[]"
#how to call this function?
def cleanse(message):
cleansed_message = ''
remove_characters = "+-=[]"
for i in message:
if i not in remove_characters:
cleansed_message = cleansed_message + i
cleansed_message = cleansed_message.lower()
return cleansed_message
def word_counter(message):
# I tried calling the cleansed message here
message = cleanse(message)
count = 0
for i in message:
count = len(message.split())
return count
只需将message=cleanse(message)
放在函数定义的顶部(或至少在返回计数之前)。当函数返回值时,它将退出,因此之后的所有代码都不会执行。(请注意,此规则有一些例外,但出于您的目的,可以这样认为。)然后只需在程序体中调用word\u counter
,如下所示:
print(word\u计数器(“这是我的超级棒的消息!”)
祝你好运
def cleanse(message):
cleansed_message = ''
remove_characters = "+-=[]"
for i in message:
if i not in remove_characters:
cleansed_message = cleansed_message + i
cleansed_message = cleansed_message.lower()
return cleansed_message
def word_counter(message):
message = cleanse(message)
print(message)
count = 0
for i in message:
count = len(message.split())
return count
if __name__ == "__main__":
msg = "Hello + Hye = Hello Hey. Your string has unnecessary characters - so please remove them"
print(word_counter(msg))
评论:
将使用消息字符串调用word_计数器,如下所示:
if __name__ == "__main__":
msg = "Hello + Hye = Hello Hey. Your string has unnecessary characters - so please remove them"
print(word_counter(msg))
由于word_计数器是一个函数,它将消息作为参数,然后将该消息传递给clean函数以清除不必要的字符,并将过滤后的输出返回到word_计数器,在该计数器中计算字符串中的字数并将计数返回给调用函数
输出
msg = "Hello + Hye = Hello Hey. Your string has unnecessary characters - so please remove them"
print(word_counter(msg))
你说得很对。但是,您需要明确地调用word\u计数器
函数您的明确意思是什么?从主函数?以下是工作代码。。当你说你想“调用”已清除的消息时,你不清楚你的意思是什么。消息是一个字符串,不能调用字符串。字符串是否表示希望调用的函数的名称?这是一个微妙但重要的区别。在word_counter函数中,我的目标是观察修改后的字符串(如果有意义的话)?感谢格式化代码。
msg = "Hello + Hye = Hello Hey. Your string has unnecessary characters - so please remove them"
print(word_counter(msg))
