Do you not give up after the introduction of the Python fairy?

Not to study for the purpose of learning, it is bullying ~ So the rogue has become rich ...

Well, it's not poverty. From one day onwards, the blog only talk about learning and feelings, do not talk about work, do not pull useless ~

What's the whole day? Let me think about ~ Well, yesterday did not complete the database, then start from here, to paste a small code, small cool suddenly ~
