What is the difference between iterators and generators?
Answer type: Single choice • with the choice of one correct answer from several proposed options
A generator is a mechanism for traversing data element-by-element, and an iterator allows you to lazily create a result when iterating.

You have been given a task. Create a class called Dog. When creating an instance of the Dog class, it must be possible to assign a value to the name property. What is the correct code option so that after creating the instance, you can also get the value of the name property?

Additional Information
Why will this code throw an error?: print(int(True) // float(False))Answer type: Single choice • with the choice of one correct answer from several proposed options
You can't divide True by False because they are boolean values
You can't divide an int into a float
Cannot divide by 0
Suppose you enter a natural integer into the variable num, using the line of code: num = int(input("Enter an integer: ")) And then you want to concatenate this number with the string “Python” to get, for example, “1234Python” . What do you need for this?
Answer type: Multiple choice • with the choice of several correct answers from the proposed options
I will write a code that will output a line. This will be enough: print(num + "Python")
I'll add try: except: blocks and handle the TypeError exception
I will give a variable num with type 'str'

We have a tuple my_tuple = (1, 82, 21). How can we add the new value 38 to it? Let's agree that we are not creating a new tuple, but we want to add a new element to it
Answer type: Single choice • with the choice of one correct answer from several proposed options
my_tuple.append(38)
my_tuple[3] = 38
A tuple is an immutable set of data
