Decode () and encode ()

In Python, we use decode () and encode () to decode and encode

In Python, the Unicode type is used as the underlying type of the encoding. That

Decode encode

STR---------> Unicode--------->str

u = U ' China ' #显示指定unicode类型对象u

str = u.encode (' gb2312 ') #以gb2312编码对unicode对像进行编码

str1 = U.encode (' GBK ') #以gbk编码对unicode对像进行编码

str2 = U.encode (' utf-8 ') #以utf-8 encoding encodes Unicode pairs of images

u1 = Str.decode (' gb2312 ') #以gb2312编码对字符串str进行解码 to get Unicode

U2 = Str.decode (' utf-8 ') #如果以utf-8 encoding for STR decoding results, the original Unicode type cannot be restored

As in the above code, STR\STR1\STR2 are string types (str), which brings greater complexity to string manipulation.

The good news is, yes, that's python3. In the new version of Python3, the Unicode type is removed, instead it is a string type (str) that uses Unicode characters, and the string type (str) becomes the underlying type as shown below, and the encoded change to the byte type ( bytes) But the use of two functions does not change:

Decode encode

bytes------> str (Unicode)------>bytes

u = ' China ' #指定字符串类型对象u

str = u.encode (' gb2312 ') #以gb2312编码对u进行编码, Get bytes type Object str

u1 = Str.decode (' gb2312 ') #以gb2312编码对字符串str进行解码, gets the string type object u1

U2 = Str.decode (' utf-8 ') #如果以utf-8 encoding for STR decoding results, the original string content cannot be restored
