Which of the following are valid Python variable names:Agever1.3route664squarereturnhome_address

The valid Python variable names from the list you provided are:

1. route664
2. home_address

Explanation:

In Python, variable names must follow these rules:

• They must start with a letter (a - z, A - Z) or underscore (_).
• The rest of the name can contain letters, numbers, and underscores.
• They can't start with a number.
• They can't be a reserved word in Python like 'return'.

So, let's analyze each of the proposed variable names:

• Agever1.3: This is not a valid variable name because it contains a dot (.).
• route664: This is a valid variable name. It starts with a letter and the rest are numbers.
• squarereturn: This is not a valid variable name because 'return' is a reserved word in Python.
• home_address: This is a valid variable name. It starts with a letter and the rest are letters and an underscore.
