我有几个 ms access 数据库，每个数据库都有一个名为 的表PlotStatus-name-3/13/12。

我需要将每个表导入到一个.csv表中。如果我手动将表的名称更改为PlotStatus_name_3_13_12，此代码将起作用。有人知道如何使用 python 更改表名吗？

#connect to access database
for filename in os.listdir(prog_rep_local):
if filename[-6:] == ".accdb":
    DBtable = os.path.join(prog_rep_local, filename)
    conn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=' + DBtable)
    cursor = conn.cursor()
    ct = cursor.tables
    for row in ct():
        rtn = row.table_name
        if rtn[:10] == "PlotStatus":

            #this does not work:
            #Oldpath = os.path.join(prog_rep_local, filename, rtn)
            #print Oldpath
            #fpr = Oldpath.replace('-', '_')#.replace("/","_")
            #print fpr
            #newname = os.rename(Oldpath, fpr)  this does not work
            #print newname
            #spqaccdb = "SELECT * FROM " + newname


            #this workds if I manually change the table names in advance
            sqlaccdb = "SELECT * FROM " + rtn
            print sqlaccdb

            cursor.execute(sqlaccdb)
            rows = cursor.fetchall()
