python 从csv文件插入mysql数据库

一个工作遇到的问题，将excel文件的内容插入到mysql数据库中。

 

总体思路是 excel文件-->转换成csv文件-->csv文件读取-->读取数据插入mysql数据库

用到python的两个库csv和MySQLdb

下面是具体的code：

代码中数据库部分没啥好记录的，特别记录一下csv库的用法：

# Insert data from csv file.
csv_file = file('3D_PTlabs.csv', 'rb')
csv_reader = csv.reader(csv_file)
csv_reader生成的是一个迭代器，将迭代器内的内容重新整成list便于操作。
rows = [row for row in csv_reader]        
print len(rows[0])
print rows[0]
