Preface
Yesterday, when writing a small project, I encountered a requirement: import the data of txt documents into the mysql database. At first, I wanted to import TXT files directly with Mysql Workbench, but finally I found that I did not support TXT import. As a result, I went to transfer TXT to Excel, and found all kinds of garbled code problems when I imported it to Linux.
With the principle that there is nothing a programmer can't do, I handwritten a Python code and directly manipulated the file to import it. As a result, there are about 10,000 files, and the import time is about two minutes.
Here is the specific code:
Mysqlpython.py file: custom class importtxt.py file for connecting to mysql database: read TXT file and insert operation dict.txt file: TXT file to be operated
Mysqlpython.py file
From pymysql import * class Mysqlpython: def _ init__ (self,database,host= "localhost", user= "root", password= "123456", charset= "utf8", port=3306): self.database = database self.host = host self.user = user self.password = password self.charset = charset self.port = port # create data connection and cursor object def open (self): self.db = connect (host=self.host, user=self.user, password=self.password, port=self.port, database=self.database) Charset=self.charset) self.cur = self.db.cursor () # close cursor object and database connection object def close (self): self.cur.close () self.db.close () # execute sql command def zhixing (self,sql,L= []): self.open () self.cur.execute (sql,L) self.db.commit () self.close () # query function def all (self,sql L = []): self.open () self.cur.execute (sql,L) result = self.cur.fetchall () return resultif _ _ name__ = "_ _ main__": sqlh = Mysqlpython ("dictionary") sel = "select * from user" r = sqlh.all (sel) print (r)
Importtxt.py file
Import reimport sysfrom mysqlpython import Mysqlpythonsqlh = Mysqlpython ("dictionary") def insert (data): arr = data.split () name = arr [0] description = "" .join (arr [1:]) ins = "insert into words (name,description) values (% s)" sqlh.zhixing (ins, [name) Description]) def get_addr (): F = open ('. / dict.txt') lines=f.readlines () for line in lines: insert (line) f.close () return''if _ name__ = ='_ main__': print (get_addr ())
Dict.py file (I copied several files)

You can modify the regular expression for different delimiters. All the code has been posted, and the configuration of the database can be copied and modified directly.
