Jia captain today reading this "awkward school python3", this book is more biased in favor of combat, I found the problem yesterday did not understand the strings and encoded in here. This made me more confused. Before that, I need to learn some basic knowledge of computers to store data. Now the computer has only 1 and 0, called it "bit" (bit) but very convenient, so with coding, the most common is the American Standard Code for Information Interchange (ASCII)
0b1011010
90
words ( 'Z')
90
chr(90)
'with'
Alas, confused, first rest, tomorrow Jia captain a lot of work. Revolution is not successful, comrades still work ah! !
