>>> A = 'medium' ===> a is an encoded binary. It adopts the default encoding method of the operating system, similar to byte.

>>> S = U' '===> s is a unicode type, 32-bit integer, and the variable content is a unicode code word (codepoint)

>>>

'\ Xd6 \ xd0' ==> as described above, the current system is GBK encoding, And the binary value of GBK Encoding

>>> S

U' \ u4e2d '==> as mentioned above, the 4e2d code is stored, consistent with the unicode definition.

>>> Print

Medium

>>> Print s

Medium

>>> A. decode ('gbk'). encode ('utf-8') ==> After decoding a string, encode it using utf8.

'\ Xe4 \ xb8 \ xad'

>>> S. encode ('utf-8') ==> encode the code 4e2d using the utf8 encoding scheme, and output the encoded binary value and

'\ Xe4 \ xb8 \ xad' ==> the content in step 1 is consistent.
