To pass a table name as an argument in psycopg2, you can use parameterized queries. Here is an example:

import psycopg2

table_name = 'my_table'

conn = psycopg2.connect(dbname='my_database', user='my_user', password='my_password', host='my_host')
cursor = conn.cursor()

query = """
    SELECT * FROM %s;

cursor.execute(query, (table_name,))

result = cursor.fetchall()


In this example, the table name is stored in a variable called table_name, which is then passed as an argument to the parameterized query using %s. The actual value of table_name is provided as a parameter to the execute() method, along with any other parameters that the query might require.

Note that it is important to use parameterized queries instead of string concatenation to build your queries, in order to prevent SQL injection attacks.
