根据导出的查询结果拼接字符串,生成sql语句并保存到txt文件中

import os
os.chdir("C:/")
path = os.getcwd()
print(path)
f = open("sql.csv")
# print(f.read())
f.seek(0)
lst = []
n = 0
for line in f.readlines():
    if n > 0:
        fullname = line.rsplit('/', 1) #从右侧开始以第一个"/"为分隔符将字符串分割为两端,保存为2元素列表传给fullname
        filename = fullname[1].split('"') #第二个元素中还包含引号和回车,以引号为分隔符,提取出文件名
        # print (filename[0])
        str1 = "alter database rename file "
        str2 = " to '"
        str3 = "/u01/app/product/oradata/water/onlinelog/"
        str4 = "';"
        line1 = line.replace('\n', '') #删除每行的回车字符
        sql = str1 + line1 + str2 + str3 + filename[0] + str4 #拼接成sql语句
        #print(sql)
        lst.append(sql)
    n += 1
os.chdir("c:/Users/wuyi/Desktop")
f_w = open('resultSql.txt','w')
for i in range(len(lst)):
    lst[i] = lst[i] + '\n'
f_w.writelines(lst)
f.close()
f_w.close()
