Python 3: str.join() with seperator

Question

I have some code which is essentially this:

data = [\"some\", \"data\", \"lots\", \"of\", \"strings\"]
separator = \".\"

output_string = \"\"
for datum in d         


        

Answer 1

If the separator is a variable you can just use variable.join(iterable):

data = ["some", "data", "lots", "of", "strings"]
separator = "."


print(separator.join(data))
some.data.lots.of.strings

Answer 2

output_string = ".".join(data)

if you have integers or non-strings in data, then

output_string = ".".join( str(x) for x in data )
