Python: Print a list after removing specified elements

Sample Solution:

Python Code:

# Create a list 'color' with several color strings
color = ['Red', 'Green', 'White', 'Black', 'Pink', 'Yellow']

# Use a list comprehension to create a new list 'color' that includes elements from the original list
# but only if their index (i) is not in the specified indices (0, 4, 5)
color = [x for (i, x) in enumerate(color) if i not in (0, 4, 5)]

# Print the modified 'color' list, which excludes elements at indices 0, 4, and 5
print(color)

Sample Output:

['Green', 'White', 'Black']

Explanation:

In the above exercise -

color = ['Red', 'Green', 'White', 'Black', 'Pink', 'Yellow'] -> Creates a list color containing some color names.

color = [x for (i,x) in enumerate(color) if i not in (0,4,5)] -> Creates a new list using a list comprehension. The list comprehension loops over each element (i, x) in color and includes only those elements where i is not in (0, 4, 5).

enumerate(color) returns a list of tuples containing the index and value of each element in color.
(i, x) unpacks each tuple into two variables, i and x.
if i not in (0, 4, 5) checks if the index of the current element is not equal to 0, 4 or 5.
[x for ...] creates a new list containing only the values of the elements that meet the condition specified in the if statement.

After this code runs, the list color will only contain the elements that have an index of 1, 2, or 3. So, the colors 'Green', 'White', and 'Black' will be included, and 'Red', 'Pink', and 'Yellow' will be removed.
