This article to share with you is about python how to solve the coding error UnicodeEncodeError: 'ascii' codec can't encode characters in pos problem, Xiaobian think quite practical, so share with you to learn, I hope you can read this article after harvest, not much to say, follow Xiaobian to see it.

Problem Description:

The same code runs OK on one server, and the other runs with the following error:

File "/data/soft/knowledge_etl/databus-gedai-v1/schedule_job/main.py", line 270, in print ('demo\u4e3a\u5168\u90e8kp_md5_etl\u4e3b\u4efb\u52a1\u4e3a\u4f8b\u5b50') UnicodeEncodeError: 'ascii' codec can't encode characters in position 4-6: ordinal not in range(128) 1-Location str.decode ('utf-8')#decode is used to convert strings encoded in other codes into unicode encodings #python2s = u'Chinese's.decode ('utf-8') print s#Chinese #python3#Because in python3, all strings are encoded in Unicode, str type is uniformly used to save, and str type has no decode(decode) method.

Cause analysis: Sometimes the locale of a process is set to support only ASCII characters (e.g. LANG=C). Python will then set the standard output and standard error encoding to ascii, causing the output to be incorrect in Chinese. In the Visual Studio Code editor here, it is set to ascii code, causing the output Chinese error.

import sysimport iodef setup_io():sys.stdout = sys.__ stdout__ = io.TextIOWrapper(sys.stdout.detach(), encoding='utf-8', line_buffering=True)sys.stderr = sys.__ stderr__ = io.TextIOWrapper(sys.stderr.detach(), encoding='utf-8', line_buffering=True)setup_io()#sys.stdout is an io.TextIOWrapper with a buffer attribute containing an io. Buffered Writer. We use it to make a new io.TextIOWrapper, specifying the encoding as UTF-8. In addition to encoding, error handling and buffering can also be set here. So this trick can also be used to tolerate coding errors and change the buffering of standard outputs. s1='I miss you'print(s1)#I miss you ~ correct The above is how python solves the coding error UnicodeEncodeError: 'ascii' codec can't encode characters in pos problem, Xiaobian believes that some knowledge points may be seen or used in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
