Python Program to Check if a table exist
To check if a table exists in a MySQL database using Python, you can use the `SHOW TABLES` statement to retrieve a list of all the tables in the database and then check if the specified table is in the list.

Here's an example Python program that checks if a table exists in a MySQL database :

Example :
import mysql.connector

# Create a connection to the MySQL server
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  password="yourpassword",
  database="mydatabase"
)

# Create a cursor object to execute SQL statements
mycursor = mydb.cursor()

# Check if a table exists
mycursor.execute("SHOW TABLES")
tables = mycursor.fetchall()

table_name = "customers"
if (table_name,) in tables:
  print("The table exists.")
else:
  print("The table does not exist.")​
In this example, the `mysql.connector` module is imported and a connection is created to the MySQL server, just like in the previous example.

Next, a cursor object is created using the `cursor()` method of the connection object.

To check if a table exists, the program executes the `SHOW TABLES` statement using the `execute()` method of the cursor object. The `fetchall()` method is then called to retrieve all the rows returned by the query. The result is a list of tuples, where each tuple contains the name of a table in the database.

The program then checks if the specified table name exists in the list of tables by using a `for` loop and an `if` statement. If the table exists, the program prints a message indicating that the table exists. If the table does not exist, the program prints a message indicating that the table does not exist.

Finally, the connection is closed using the `close()` method of the connection object. Note that the `close()` method is not called in this example, but you should always close the connection when you are finished with it to free up resources.
