Using commas and hyphens as a string separator.

list_abc = ['aaa', 'bbb', 'ccc']

string = ','.join(list_abc)
print(string)

string = '-'.join(list_abc)
print(string)

string = '\n'.join(list_abc)
print(string)

my_list = ['Hello', ' ', 'World', '!']
result = ''
for element in my_list:
    result += element
print(result)  # Output: Hello World!
