<prompt> Explain what the function count_words does in Python.  <response>: The function count_words is not a built-in function in Python, but rather it is a custom function that can be written to count the number of words in a given string or text. The specific details of the function may vary depending on how it is implemented.In general, a count_words function in Python would take a string as an input and count the number of words within that string. This can be done by splitting the string into a list of words and counting the number of elements in the list. For example, the string can be split using the split method, which splits the string at every occurrence of a specified separator by default, any white space character is a separator, and returns a list of the resulting substrings. The length of the list would be the number of words in the original string.Here is an example of how a count_words function could be implemented in Python:def count_wordstext: split the text into a list of words words text.split return the number of words in the list return lenwordsThe function takes the input text, splits it into a list of words using the split method, and returns the length of the words list, which is the number of words in the text.
