「python学習」pythonでファイルを読み取って、ｍysqlでデータを挿入する方法
Javaコード：
import os
import mysql.connector
config = {
'user’: 'root’,
'password’: '******’,
'host’: '127.0.0.1’,
'database’: 'startnews24_com_db’,
'raise_on_warnings’: True,
}
cnx = mysql.connector.connect(**config)
class ReadFile:
def readLines(self):
f = open(“E:/data_startnews24/2015-3-13.txt", “r", 1, “utf-8")
i=0
list=[]
for line in f:
strs = line.split(“\t")
if len(strs) != 5:
continue
data=(strs[0], strs[1], strs[2], strs[3], strs[4].replace(“\n",""))
list.append(data)
cursor=cnx.cursor()
sql = “insert into data_test(uid,log_date,fr,is_login,url)values(%s,%s,%s,%s,%s)"
if i>5000:
cursor.executemany(sql,list)
cnx.commit()
print(“挿入")
i=0
list.clear()
i=i+1
if i>0:
cursor.executemany(sql,list)
cnx.commit()
cnx.close()
f.close()
print(“ok")
def listFiles(self):
d = os.listdir(“E:/data_startnews24/")
return d
if __name__ == “__main__":
readFile = ReadFile()
readFile.readLines()
