我能夠得到這個輸出我的MYSQL命令,我已經刪除了安全性,但是當我嘗試寫這個製表符分隔輸出到CSV時,我不斷收到錯誤。任何幫助提升Python新手,將不勝感激。製表符分隔到csv
#!/usr/bin/pytho
import sys, csv
import MySQLdb

import mysql.connector
import subprocess
import string
if __name__ == '__main__':
du = sys.argv[1]
csv_home = '/home/oatey/bundle_' + du + '.csv'
input = sys.stdin
output = sys.stdout
#read and rewrite to file with arguement
new = open("/home/oatey/valid.sql2", "w")
with open("/home/oatey/bundle.sql")as write_query:
#read_file = write_query.read()
for line in write_query:
lr = line.replace('{$$}', du)
print lr
new.write(lr)
new.close()
write_query.close()
with open("/home/oatey/valid.sql2") as w:
mysql_output = subprocess.check_output(MYSQL_COMMAND, stdin=w)
#print mysql_output
b = open("/home/oatey/" + du + ".txt", "r+")
#",".join("%s" % i for i in mysql_output
b.write(mysql_output)

b.close()
#read tab-delimited file
with open("/home/oatey/" + du + ".txt", 'rb') as data:
cr = data.readlines()
contents = [line for line in cr]
with open("/home/oatey/" + du + ".csv", "wb") as wd:
cw = csv.writer(wd, quotechar='', quoting=csv.QUOTE_NONE)
wd.write(contents)
什麼是錯誤您收到? –
當你通過子進程執行你的命令時,可能會要求mysqldump爲你完成這項工作並導出爲CSV作爲選項嗎? 'mysqldump -u [username] -p -t -T/path [database] --fields-enclosed-by = \「--fields-terminated-by =,' – Majid
通常情況下是...但這是一個自動化步驟的一部分,用戶輸入csv的路徑... – goat
