How to return a concatenated list in python?

Question

Let's say I have a function that takes a list and returns a concatenated string.

stringList = ["hello", "world"]
for string in stringList():
    #concatenate all strings in list
return newString

Expected output should be "helloworld"

My original idea was:

for string in stringList():
    string = string + ""
return string

However, this would only return the last element of a list. I'm not sure how to fix this. Also, I cannot use the print function and simply do:

print(string, end="")

Answer 1

You could try the inbuilt function of python strings called join

string = "".join(stringList)

Answer 2

Just use str.join:

"".join(stringList)
