用python的mysql.connector模块运行代码结果为空，但是在数据库命令行下运行有结果

Question

cursor.execute("SELECT article_num1,article_num2,citation_num1,citation_num2,shortest_path_length FROM colla WHERE colla.author_name1 = '%s'",name)

结果为None

但是在数据库的命令行里运行就有结果，这是什么原因？

Answer 1

cursor.execute("SELECT article_num1,article_num2,citation_num1,citation_num2,shortest_path_length FROM colla WHERE colla.author_name1 = %s",（name,))

This is the best answer I found. I got the correct result.
Reminder, I am using python3.4

Answer 2

How did you get the results,cursor.fetchone()

Answer 3

The parameters of execute are wrong. The second parameter must be a sequence or dict. It can be changed to the following.

cursor.execute("SELECT article_num1,article_num2,citation_num1,citation_num2,shortest_path_length FROM colla WHERE colla.author_name1 = '%s'",（name,))
