What does this syntax mean in Python?

Question

What does the comma in the declaration below mean? Does it define two variables at once?

resp, content = client.request(request_token_url, \"GET\")

Answer 1

It creates a tuple. In this case, the tuple is of two variables, which get assigned the result from request().

request() returns a tuple, which is then automatically unpacked into the left-hand tuple during assignment.

If you had just

result = client.request(request_token_url, "GET")

that would assign the tuple directly to result. Then you would be able to access the response at result[0], the first value in the tuple, and the content would be in result[1].
