Python on the misunderstanding of the bytes class method to digital conversion, the importance of JSON

This article originated from a mistake, found in bytes () can fill in the numbers, turned out is also bytes type, impatient to put the things inside decode out. The result is empty. Come on, think it's a command unskilled. In fact, the logic is wrong.

A1 = bytes ('one', encoding='utf-8')print  = a1.decode ()print= bytes (one)print= A2.decode () Print (B2)

Wrong logic: bytes int to byte type, then converts byte type to int by decode

int can indeed be converted to byte, but byte is not going to go back int. Unless you define a function yourself or use some of the more complex commands built in.

-----------------------------------------------

The basic tutorial will generally ask you to turn int into STR, then STR to byte, decode, byte to str, then Int. It's also very troublesome. Though the logic is right.

It seems that in a simple programming, STR is not around the past!

Secret weapon JSON

Lenovo to more, in case I was an array to go to byte, or dictionary, and so on, it would be more complicated.

In fact, you should not forget a tool that is not complicated, that is, JSON. With JSON, you can soar all the data transformations and restores!

Not just arrays, dictionaries, even music, video files. JSON as competent
