Which of the following is an invalid Python assignment statement?Question 12Select one:a.a = b = 123b.‘3’ = 3c.x = int(“123”)d.y = Nonee.z = “hi” * 10

To identify the invalid Python assignment statement, let's evaluate each option:

1. Option a: a = b = 123
   This statement is valid. It assigns the value 123 to both a and b.

2. Option b: ‘3’ = 3
   This statement is invalid. In Python, you cannot assign a value to a literal (in this case, the string '3'). Assignment can only be made to variable names.

3. Option c: x = int(“123”)
   This statement is valid. It converts the string "123" to an integer and assigns it to x.

4. Option d: y = None
   This statement is valid. It assigns the value None to the variable y.

5. Option e: z = “hi” * 10
   This statement is valid. It assigns a new string (the result of "hi" repeated 10 times) to z.

Final Answer

The invalid Python assignment statement is b. ‘3’ = 3.
