Detailed explanation of Python's method of reading and writing sqlite3 database and writing data to Excel

这篇文章主要介绍了Python实现读写sqlite3数据库并将统计数据写入Excel的方法,涉及Python针对sqlite3数据库的读取及Excel文件相关操作技巧,需要的朋友可以参考下

本文实例讲述了Python实现读写sqlite3数据库并将统计数据写入Excel的方法。分享给大家供大家参考，具体如下：

  src = 'F:\\log\\mha-041log\\rnd-log-dl.huawei.com\\test'
#  dst = sys.argv[2]
  dst = 'F:\\log\\mha-041log\\rnd-log-dl.huawei.com\\test\\mha-041log.db'
#  dst_anylyzed = sys.argv[3]
  dst_anylyzed = 'F:\\log\\mha-041log\\rnd-log-dl.huawei.com\\test\\mha-041log.xlsx'
 cx = sqlite3.connect(dst)
  init_table_title(cx, startcoreapp_table)
  init_table_title(cx, startwechat_table)
  init_table_title(cx, coreappjankframe_table)
  init_table_title(cx, wechatjankframe_table)
  init_table_title(cx, otherapp_table)
  os.path.walk(src, visit_zipfile, cx)

数据库初始化方法：

def init_table_title(c, work_table):
  global base_index
  global info_index
  c.execute('DROP TABLE IF EXISTS ' + work_table);
  c.execute('CREATE TABLE ' + work_table + ' \
           (Product TEXT NOT NULL, \
           Version TEXT NOT NULL, \
           Imei TEXT NOT NULL, \
           Date TEXT NOT NULL, \
           Eventid TEXT NOT NULL, \
           HappenTime TEXT NOT NULL, \
           FIELDNAME TEXT NOT NULL, \
           CASENAME TEXT NOT NULL)');
  return
