update multiple rows with different values python and mysql

Question

i want to update multiple rows with different values.

for example my table is :

id | Name | Data

1 |ahmad | year 2015

2 | ali | year 2014

i want my table to look like this:

id | Name | Data | number

1 |ahmad | year 2015 | 2

2 | ali | year 2014 | 3

There are more than 7000 rows i can't fill them one by one.

The query i am trying to do so in python is:

 #words count in a tweet
    words= processedRow.split()
    fdist2=len(words)

    for val in cursor.fetchall():
        cursor.execute("""UPDATE TWEETER1 SET t1=%s where id = %s""",(fdist2,val))
        db.commit()

Kindly help me in doing my work. Thank you

Answer 1

Yes, you can. 7000 is a low number for a computer.

You could try to optimise it for >100k to use multiple database connections or not to commit on each update but that's outside the scope of your questions.
