jingxian 通过本文主要向大家介绍了python 调用bat,python bat,python vcvarsall.bat,bat运行python,python 执行bat等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
实例如下：
# 环境: python3.x
def getExportDbSql(db, index):
# 获取导出一个数据库实例的sql语句
sql = 'mysqldump -u%s -p%s -h%s -P%d --default-character-set=utf8 --databases mu_ins_s%s > %s.s%d.mu_ins_%d.sql' %(db['user'], db['pwd'], db['host'], db['port'], index, db['server'], index, index)
return sql
def createDbBackupFile(fname, dbList):
# 生成数据库导出的语句保存到文件
if not fname or not dbList:
return False
f = open(fname, 'w')
if f:
f.write('echo @off\n\n')
for db in dbList:
for index in db['indexList']:
f.write('REM %s.s%d\n' %(db['server'], index))
f.write('%s\n\n' %getExportDbSql(db, index))
f.write('\n')
f.close()
return True
return False
def initDb(user, pwd, host, port, server_name, indexList):
# 生成db字典对象并返回
db = {}
db['user'] = user
db['pwd'] = pwd
db['host'] = host
db['port'] = port
db['server'] = server_name
db['indexList'] = indexList
return db
def displayDb(db):
print('user =', db['user'])
print('pwd =', db['pwd'])
print('host =', db['host'])
print('port =', db['port'])
print('server =', db['server'])
print('indexList =', db['indexList'])
print('\n')
def displayList(list):
for item in list:
displayDb(item)
if __name__ == '__main__':
db1 = initDb('root', '123456', '127.0.0.1', 3306, 'th1', [10000, 1, 3])
db2 = initDb('root', '123456', '127.0.0.1', 3306, 'th2', [10000, 1])
dbList = []
dbList.append(db1)
dbList.append(db2)
#displayList(dbList)
createDbBackupFile('export00.bat', dbList)

以上这篇利用python生成一个导出数据库的bat脚本文件的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
