_mysql_connector.mysqlinterfaceerror: python type list cannot be converted
This error occurs when trying to pass a Python list object to a MySQL connector, which is not a valid data type for conversion. MySQL connectors expect the data to be in a specific format that can be directly inserted into a MySQL database.
To resolve this issue, you need to convert the list object to a valid MySQL data type before passing it to the MySQL connector.
Example:
import mysql.connector
# Assuming you have the following list
data_list = [1, 2, 3, 4, 5]
# Convert list to a valid MySQL data type (e.g., comma-separated string)
data_string = ','.join(str(x) for x in data_list)
# Establish a connection to MySQL database
connection = mysql.connector.connect(
host="localhost",
user="your_username",
password="your_password",
database="your_database"
)
# Create a cursor object to execute SQL queries
cursor = connection.cursor()
# Example query using converted data
query = "INSERT INTO your_table (column_name) VALUES ('{}')".format(data_string)
# Execute the query
cursor.execute(query)
# Commit the transaction
connection.commit()
# Close the cursor and connection
cursor.close()
connection.close()
In this example, we have a list object called ‘data_list’ containing values [1, 2, 3, 4, 5]. To insert these values into a MySQL database, we convert the list to a string using the ‘join’ function and pass it as a parameter in our query. The resulting query will be “INSERT INTO your_table (column_name) VALUES (‘1,2,3,4,5’)” if the table has a single column called ‘column_name’.
