python> "I don't understand the meaning of", = "> (Solution) One Element Tuples: You answered the comment

I need to understand the code written in python, and today (2015-03-25) I am studying python for the first time.

In that code

field_len, = unpack(">H", fin.read(2))

However, the meaning of "," before = is not found by google search.

I would like somebody to teach.

(Addition 150325) I learned from shiena and ssh0. Thank you.
