python-mysqlHow do I use Python and MySQL to get the number of rows?

Using Python and MySQL to get the number of rows is very easy. The following example code will illustrate how to do this:

import mysql.connector

# Connect to the database
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword"
)

# Create a cursor
mycursor = mydb.cursor()

# Execute a query
mycursor.execute("SELECT * FROM table_name")

# Get the number of rows
num_rows = mycursor.rowcount

# Print the number of rows
print(num_rows)

Output example

1. Import the mysql.connector module.
2. Connect to the database.
