我的文本文件如下所示：10May2013   3.1   http://ncbi.org p.sojae_aafeatureimp    p.sojae_aafeatureimp10May2013   3.2   http://ncbi.org   p.sojae_aasequenceimp   p.sojae_aasequenceimp10May2013   3.3   http://ncbi.org   p.sojae_blatalignment   p.sojae_blatalignment如何解析這些單獨的行并將其插入到數據庫中？數據庫結構：（日期，版本，URL，名稱，描述）我必須使用Python將文本文件中的值插入mysql。到目前為止，我的腳本是這樣的：import MySQLdb, csv, syswith open('externaldatabase.txt') as textfile:  csvreader = csv.reader(textfile)  csvdata = []  for row in csvreader:  csvdata.append(row)conn = MySQLdb.connect (host = "localhost",user = "username", passwd = "password",db = "database_name")c = conn.cursor()for row in csvdata:# Insert a row of datac.execute("INSERT INTO externaldatabase (release_date, version, download_url, name, description) VALUES ('%s', '%s', '%s', '%s', '%s')" % (row))conn.commit()c.close()但它讓我出錯：Traceback (most recent call last):File "csv1.py", line 16, in <module>c.execute("INSERT INTO externaldatabase (release_date, version, download_url, name, description) VALUES ('%s', '%s', '%s', '%s', '%s')" % (row))TypeError: not enough arguments for format string
