Python Workbook-Topic answer reference

question No. 0000: Add the red number to the top right corner of your QQ head (or Weibo avatar)

Python Library: Everyone will say PIL, but according to StackOverflow's advice, adopt pillow (PiL a fork)
Document: Imagefont Module

question No. 0001: generate an Activation code (or coupon) for your app

1. If you do it simply, use UUID it directly. Recommended Useuuid1
2. You can use the random module to generate it yourself using id+

My approach: To see someone say:

The Apple Store app's Activation Code (coupon) is typically 10-bit long and consists of lowercase letters and numbers

So I am: hex(id)+rand(‘g‘-‘z‘)+rand(char) where rand (' G '-' Z ') is the delimiter.
