python binascii binary conversion instance

As follows:

#coding:utf-8

import binascii

a = 'worker'

# First put worker convert to 2 Binary data is then used 106 Binary representation 

b = binascii.b2a_hex(a)

print b

# and b2a_hex Contrary 

print binascii.a2b_hex(b)

# This function and b2a_hex()1 kind 

c = binascii.hexlify(a)

print c

# This function and a2b_hex()1 kind 

print binascii.unhexlify(c)

###### Run Results ######

>>> 776f726b6572

worker

776f726b6572

worker 


python Built-in functions: 


hex():

# hold 10 Binary Conversion to Shaping 16 Binary 

>>> hex(88)

'0x58'

# Convert Floating Point to 16 Binary 

>>> 1.23.hex()

'0x1.3ae147ae147aep+0'

# Built-in function hex and binascii.hexlify() The difference is that, 

#hex Strings can only be accepted by integers but not by strings 

>>> hex('88')

Traceback (most recent call last):

 File "<pyshell#26>", line 1, in <module>

 hex('88')

TypeError: hex() argument can't be converted to hexbin():ba 





bin(): hold 10 Binary integer conversion 2 Binary character 

# hold 10 Binary Integer Conversion 2 Binary 

>>> bin(88)

'0b1011000'

>>> bin(33)

'0b100001' 



oct(): hold 10 Binary Conversion 8 Binary character 

# hold 10 Binary Conversion 8 Binary 

>>> oct(500)

'0764'

>>> oct(488)

'0750' 


chr(): hold 1 Integer conversion ASCII The corresponding single character in the code table  

# hold 1 Integer conversion ASCII The corresponding single character in the code table 

>>> chr(98)

'b'

>>> chr(97)

'a' 

ord(): and chr Instead, put ASCII Convert characters in code table to corresponding integers 

>>> ord('b')

98

>>> ord('c')

99
