Automate the boring stuff with Python: Comma Code

Question

Currently working my way through this beginners book and have completed one of the practice projects \'Comma Code\' which asks the user to construct a program which:

Answer 1

This is what I did, IMO it is more intuitive...

spam = ['apples','bananas','tofu','cats']

def ipso(x):
    print("'" , end="")
    def run (x):

    for i in range(len(x)):
        print(x[i]+ "" , end=',')


    run(x)
    print("'")

ipso(spam)

Answer 2

I tried this, hope this is what you are looking for :-

spam= ['apples', 'bananas', 'tofu', 'cats']

def list_thing(list):

#creating a string then splitting it as list with two items, second being last word
    new_string=', '.join(list).rsplit(',', 1)    

#Using the same method used above to recreate string by replacing the separator.

    new_string=' and'.join(new_string)
    return new_string

print(list_thing(spam))

Answer 3

listA = [ 'apples', 'bananas', 'tofu' ]
def commaCode(listA):
    s = ''
    for items in listA:
        if items == listA [0]:
            s = listA[0]
        elif items == listA[-1]:
            s += ', and ' + items
        else:
            s += ', ' + items
    return s
print(commaCode(listA))

Answer 4

As the function must work for all list values passed to it, including integers, therefore it should be able to return/print all values i.e. as str(). My fully working code looks like this:

spam = ['apples', 'bananas', 'tofu', 'cats', 2]

def commacode(words):

    x = len(words)

    if x == 1:
        print(str(words[0]))
    else:
        for i in range(x - 1):
            print((str(words[i]) + ','), end=' ')
        print(('and ' + str(words[-1])))

commacode(spam)

Answer 5

Here's my solution. Once I found the join method and how it worked, the rest followed.

spam = ['apples', 'bananas', 'tofu', 'cats']

def commas(h):
    s = ', '
    print(s.join(spam[0:len(spam)-1]) + s + 'and ' + spam[len(spam)-1])

commas(spam)

Answer 6

I came up with this solution

#This is the list which needs to be converted to String
spam = ['apples', 'bananas', 'tofu', 'cats']

#This is the empty string in which we will append
s = ""


def list_to_string():
    global spam,s
    for x in range(len(spam)):
        if s == "":
            s += str(spam[x])
        elif x == (len(spam)-1):
            s += " and " + str(spam[x])
        else:
            s += ", " + str(spam[x])
    return s

a = list_to_string()
print(a)
