python：从mysql表中选择

Question

I am trying to select the region of a country from a mysql table using Python. However, when I write the following code:

cur.execute("select region from player_list where country = %" % (country))

I get the following error message:

ValueError: incomplete format

I am not 100% certain what the proper format is for getting this information from a mysql table using mysql.connector.

Answer 1

您可以这样尝试：

cur.execute("select region from player_list where country = {0}".format(country))

Answer 2

这可能取决于您的ORM，但对我来说，正确的语法是：

cur.execute("select region from player_list where country = %s", [country])
