Python3 error 'latin-1' codec can't encode character solution

Python3 error 'latin-1' codec can't encode character solution

When updating the database operation, an error is reported:

UnicodeEncodeError: 'latin-1' codec can't encode character '\uff08' in position 21: ordinal not in range(256)

After Baidu, I got three solutions, of which I personally think the third is the most convenient.

1. Handling strings

code omitted

2. Set the database encoding

One way is to set when connecting to the database

db.set_charset('utf-8')
cursor.execute('SET NAMES utf8;')
cursor.execute('SET CHARACTER SET utf8;')
cursor.execute('SET character_set_connection=utf8;')

However, it didn't work for me after using this method.

Another way to set the database encoding is to change the configuration file.

• Can be encoded by db.set_charset('utf-8')querying the database

• 

• windows change database encoding

1. Find the my.ini file in the mysql installation directory (if not, copy my-medium.ini, and then rename it to my.ini). In mysql5.7, it is the my-default file.

2. Find the [client] and [mysqld] fields in the my.ini file, add default-character-set=utf8 below, save and close

3. Restart the mysql service

• Linux change database encoding

• Under mysql version 5.5

1. Open the configuration file, my configuration file is in /etc/mysql/my.cnf
2. Add default-character-set=utf8 under both [client] and [mysqld] fields, save and close
3. restart mysql service

• MySQL version 5.5 and above

1. Open the configuration file, my configuration file is in /etc/mysql/my.cnf

2. Add under [mysqld]:

   character-set-server=utf8

   collation-server=utf8_general_ci

3. restart mysql service

• After setting the code successfully

3. Set parameters when connecting to the database

db = pymysql.connect("localhost","root","00000000","TESTDB" ,use_unicode=True, charset="utf8")

Set use_unicode and charset parameters
