Modifying your code a little bit...

def lister():
    listed = []
    while True:
        print('type what you want to be listed or type nothing to exit')
        inputted = input()
        if inputted == '':
            break
        else:
            listed.append(inputted) # removed the comma here

    print(', '.join(listed[:-2]) + ' and ' + listed[-1])  #using the join operator, and appending and xxx at the end
lister()
