Use Python's built-in modules and functions to convert the number of different binary numbers

BINASCII module:
It contains a function that converts a binary value into a 16 binary, which can also be reversed. #binary_value是二进制数值不是字符串, not 1010 of the int type.

Binascii.b2a_hex (binary_value) # #binary_value general read binary file can get  >> ' 89 ' 
 
   
 
  

Python comes with the BUILTIN function:
Bin (num) decimal value = = = "Binary string"

Bin (Ten)  >> ' 0b1010 ' 
 
   
 
  

Oct (num) decimal value = = = "Octal string"

Oct (Ten)  >> ' 012 ' 
 
   
 
  

Hex (num) decimal value = = = "Hex string"

Hex (  >> ' 0x14 ') 
 
   
 
  

Int (str, base) Other binary string = = = "Decimal value, where base represents STR specifically belongs to which binary, if 2 means str is binary, default base is decimal

Int (' 2 ') >>20 int (' 20 ', 
 
   
  
   
    
    8) >>8 
   
    
     
     int (' + ', ' + ') ' (' + ') ', ' >>2 int ', >>20 
    
     
      
      int (' + ', +) >>32 
     
       
     
      
    
     
   
    
  
   
 
  

Character and number conversion functions:
chr (int) integer-to-character

Chr  >> ' A ', 
 
   
 
  

Ord (CHR) character turn-integer

Ord (' a ')  >>97, 
 
   
 
  

Finally, give an example of reading a picture file binary content:

#!/usr/bin/env python  #encoding: utf-8 import Binascii   

1010 Brush screen effect, is not a bit of the hacker Empire Bright Ah, hehe
