Convert Python List to a Delimited String
This is easy to do with the join command, though the syntax may not be immediately obvious.
So if you create a list:
x = ["abc","def","ghi","jkl"]
And wanted to convert that to a comma-separated list (for example, to store in a file), you would do this:
",".join(x)
And it would result in:
'abc,def,ghi,jkl'
Or if you wanted it to be a tab-delimited string, you would do this:
"\t".join(x)
