Using Python variables in MySQL insert statement

问题

I've been trying for a while now and have look online and can't figure it out.

Variables are numbers and animals

sql = ("INSERT INTO favourite (number, info) VALUES (numbers, animals  )")
cursor.execute(*sql)
conn.comit()

Use:

sql=("INSERT INTO favourite (number, info) VALUES ({},{})".format(numbers,animals))

Its always good to use format as per future references. Check https://docs.python.org/release/3.1.5/library/stdtypes.html#old-string-formatting-operations

回答2:

sql = ("INSERT INTO favourite (number, info) VALUES (%s, %s)", (numbers, animals))

for safety, always use escape, see http://dev.mysql.com/doc/refman/5.7/en/string-literals.html

I think the following should work. Let me know how it works out for you.

sql=("INSERT INTO favourite (number, info) VALUES ({},{})".format(numbers,animals))
