defcount_words(text):num_words=len(text)returnnum_words 1. 2. 3. 在上面的代码中,text是要统计字数的文本。我们使用len()函数直接计算文本的字符个数,并将结果返回。 下面是一个使用count_words()函数统计文本字数的示例: text="Hello, world!"num_words=count_words(text)print("Number of words:",n...

The complexity of thecount()function isO(n), wherenis the number of factors present in the list. The code below usescount()to get the number of occurrences for a word in a list: words = ['hello','goodbye','howdy','hello','hello','hi','bye']print(f'"hello" appears{words.count...
Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot ...

函数定义应包含简短描述其功能的 docstring（文档字符串），紧随其后的是参数列表，形如：def calculate_total(quantity: int, price_per_item: float) -> float: """ Calculate the total cost given quantity and price per item. Args: quantity (int): The number of items. price_per_it...
