Joining elements of a list

Question

I have a list of tuples like:

data = [(\'a1\', \'a2\'), (\'b1\', \'b2\')]

And I want to generate a string like this: \"(\'a1\', \'a2\

Answer 1

Use a generator to cast the tuples to strings and then use join().

>>> ', '.join(str(d) for d in data)
"('a1', 'a2'), ('b1', 'b2')"
