When Python is installed, the default encoding is ASCII, and when non-ASCII encoding occurs in the program, Python processing often reports such an error unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0x?? In position 1:ordinal No in range, Python does not handle non-ASCII encoding, it is necessary to set its own default encoding python, generally set to UTF8 encoding format.Query system default encoding you can enter the following command in

The problem is as follows:‘gbk‘ codec can‘t decode byte 0x80 in position 34: illegal multibyte sequenceIn fact, the solution is quite simple, the error prompted the "GBK" coding problem, then where will our code problems?1.

When you use Python to write a file, or when you write a network stream to a local file, you will most likely encounter: Unicodeencodeerror: ' GBK ' codec can ' t encode character ' \xa0 ' in position ... This problem. There are a lot of similar files on the web about how to solve this problem, but it is encode,decode related, is this the real cause of the problem? No. Many times, we used decode and encode, tried all kinds of coding, utf8,utf-8,gbk,gb

Brief introduction CODEC is actually an acronym for the prefix of the coder and decoder two words. Compressioncodec defines a compression and decompression interface, and the codec we're talking about is a class that implements some of the compressed formats of the Compressioncodec interface, and here's a list of these classes: Using Compressioncodes to decompress Compressioncodec has two methods to fa
