Psycopg2 / PostgreSQL 中的硬编码和冗余代码？

如何解决Psycopg2 / PostgreSQL 中的硬编码和冗余代码？

我目前正在学习数据工程课程，对数据建模部分提供的示例和练习感到有点傻眼：

一切都是硬编码的，“复制粘贴”统治着这个地方......

这是一个简单的例子：

try: 
    cur.execute("INSERT INTO music_store2 (transaction_id,customer_name,cashier_name,year,albums_purchased) \
                 VALUES (%s,%s,%s)",\
                 (1,"Amanda","Sam",2000,"Rubber Soul"))
except psycopg2.Error as e: 
    print("Error: Inserting Rows")
    print (e)

try: 
    cur.execute("INSERT INTO music_store2 (transaction_id,"Let it Be"))
except psycopg2.Error as e: 
    print("Error: Inserting Rows")
    print (e)
    
try: 
    cur.execute("INSERT INTO music_store2 (transaction_id,\
                 (2,"Toby","My Generation"))
except psycopg2.Error as e: 
    print("Error: Inserting Rows")
    print (e)
    
try: 
    cur.execute("INSERT INTO music_store2 (transaction_id,\
                 (3,"Max","Bob",2018,"Help!"))
except psycopg2.Error as e: 
    print("Error: Inserting Rows")
    print (e)
    
try: 
    cur.execute("INSERT INTO music_store2 (transaction_id,"Meet the Beatles"))
except psycopg2.Error as e: 
    print("Error: Inserting Rows")
    print (e)

我必须承认，乍一看，我不禁认为这真的很糟糕，很难维护代码，而使用变量和循环会更好。

然而，想起我有时会成为一个无知和傲慢的傻瓜，我退后一步，不要急于下结论。

难道这真的是标准做法吗？

所有这些硬编码和复制粘贴在这里有充分的理由吗？

非常感谢您的评论
