Write a function that accepts a list of strings and concatenates them-CodePudding

Write a function called concat() that takes a list of strings as an argument and returns a single string that is all the items in the list concatenated (put side by side). (Note that you may not use the join() function.)

Sample run:
print( concat(['a', 'bcd', 'e', 'fg']) )
abcdefg

CodePudding user response：

In Python, you can just use the operator to concatenate two strings. In your case, you can do something like this:

def concat(list_args):
    res = ""
    for w in list_args:
        res  = w
    return res

Then if you run

print(concat(['a', 'bcd', 'e', 'fg']))

you get abcdefg
