Identify the error in the syntax of the following code: def is_year(year): if year % 4 == 0: print('Year is divisible by 4') else year % 4 != 0: print('Year is not divisible by 4') (1 point) Responses You cannot add a conditional statement after the else keyword.

The correct identification of the error in the syntax of the code is:

You cannot add a conditional statement after the else keyword.

The "else" statement should not have a condition directly following it. Instead, it serves as a catch-all for the condition specified in the preceding "if" statement. To fix the code, it should simply use "else:" without a condition.

Here's the corrected code:

def is_year(year):
    if year % 4 == 0:
        print('Year is divisible by 4')
    else:
        print('Year is not divisible by 4')
How can we filter out numbers less than 2 in a number sequence to find prime numbers?(1 point) Responses Our code needs to throw an error if numbers less than 2 are given. Our code needs to throw an error if numbers less than 2 are given. We can have a predefined list of all prime numbers and check if the given number is inside that list. We can have a predefined list of all prime numbers and check if the given number is inside that list. We can test numbers less than 2 by checking if it is divisible by 2. We can test numbers less than 2 by checking if it is divisible by 2. We can have a conditional check to filter out numbers less than 2

The correct approach to filter out numbers less than 2 in a number sequence to find prime numbers is:

We can have a conditional check to filter out numbers less than 2.

Prime numbers are defined as natural numbers greater than 1 that are not divisible by any other numbers except for 1 and themselves. Therefore, checking whether a number is less than 2 allows us to exclude it from consideration as a prime number.

For example, the code could look something like this:

def is_prime(n):
    if n < 2:
        return False
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return False
    return True

This function directly filters out numbers less than 2 and checks the remaining numbers for primality.

Consider a list [a, b, c, d]. Which element exists at index 4?(1 point) Responses the element a the element a the element b the element b the element d the element d There exists no element at index 4

The correct response is:

There exists no element at index 4.

In Python, indexing starts at 0. For the list [a, b, c, d], the indices of the elements are as follows:

  • Index 0: a
  • Index 1: b
  • Index 2: c
  • Index 3: d

Since the list contains only 4 elements, the available indices are 0 to 3. Therefore, there is no element at index 4, which would exceed the bounds of the list.

Which of the following is the method of list traversal?(1 point) Responses for loop for loop if-else if-else condition if-else if-else condition if condition if condition if-else condition

The correct response is:

for loop

The for loop is a common method used for traversing lists (and other iterable objects) in Python. It allows you to iterate over each element in the list one at a time.

For example, you can use a for loop to traverse a list like this:

my_list = [1, 2, 3, 4]
for item in my_list:
    print(item)

This code will print each element of my_list.
