Given the following code, what is the type of x which is printed out in each iteration?
```python
my_list = [['tiger', 'lion', 'leopard'], ['camel', 'llama', 'alpaca'], ['zebra', 'donkey', 'wildebeest']]
for x in my_list:
print(x)
```
Instruction: Choose the option that best answers the question.
A. A list of strings
B. A tuple
C. A string
D. A list of lists
Answer (1)
The question asks about the type of x printed out in each iteration of the given Python code.
The code provided is:
my_list = [['tiger', 'lion', 'leopard'], ['camel', 'llama', 'alpaca'], ['zebra', 'donkey', 'wildebeest']]
for x in my_list: print(x)
Let's break it down step-by-step:
Understanding the Structure of my_list :
my_list is a list containing three elements.
Each element in my_list is itself a list of strings.
Therefore, my_list is a list of lists.
Iteration Over my_list :
The for loop iterates over each element in my_list.
In each iteration, x is assigned to one of the elements of my_list, which are lists of strings.
Type of x :
Since each element in my_list is a list, the variable x will be a list in each iteration.
Specifically, x will be a list of strings in each iteration.
Thus, the type of x that is printed out in each iteration is "A list of strings."
The correct multiple-choice option is:
A list of strings
