I am wondering how to convert multiple string in a list into one string in a list?

It will be like this:

input:["a", "b", "c"]
output:["a,b,c"]

Thanks a lot!

You can use join()

string = ["a", "b", "c"]
[','.join(string)] #if you want to return it inside a list otherwise
','.join(string)

my_string = ["a", "b", "c"]
new_string = []
for s in my_string:
    new_string.append(s)

print (new_string)

output ['a', 'b', 'c']

  • this just copies over one list to another list, and is a rather inefficient way to do that. I don't see the point in doing that. – rv.kvetch Sep 21 '22 at 04:06

Create a new array, and then add it in a loop, append.
