Write a function that takes a list value as an argument and returns a string with all the items separated by a comma and a space

, with and inserted before the last item. For example, passing the previous spam list to the function would return 'apples, bananas, tofu, and cats'. But your function should be able to work with any list value passed to it.

Answer:

The function in Python is as follows:

def myfunction(mylist):

    listitems = ""

    for i in range(len(mylist)):

         if (i < len(mylist)-1):

              listitems = listitems + mylist[i] + ", "

         else:

              listitems = listitems + "and "+mylist[i]

   

    return listitems

Explanation:

This defines the function

def myfunction(mylist):

This initializes an empty string which in the long run, will be used to hold all strings in the list

    listitems = ""

This iterates through the list

    for i in range(len(mylist)):

For list items other than the last item, this separates them with comma (,)

         if (i < len(mylist)-1):

              listitems = listitems + mylist[i] + ", "

For the last item, this separates with and

         else:

              listitems = listitems + "and "+mylist[i]

   

This returns the required string

    return listitems

can someone help me write a 5 paragraph essay on microsoft word and why we need and how we use it? if you can please make it sou
DaniilM [7]
Here are some important points:
- we use it to do essays for school
- we can use it to do flyers for recreational events
- we can use it to do pamphlets to inform people
- it is versatile, so you can create many different types of documents
- you can create charts

This can be your opening statement

Today, there is a lot asked of a child in school. From charts to essay to projects, the average kid has at least 10 different programs they use just for one project. But there is one program that came along and changed everything, and that program is called Microsoft word. Microsoft word is valuable because it is versatile (what I wrote earlier about it being able to do many different tasks), it simplifies your experience (what i said about it being able to combine different programs into one), and it is free (you can write about how some programs charge to use their high-grade programs but microsoft is free and avaialabe on every windows
computer.)

GOOD LUCK !
