Python: Insert an element before each element of a list
Python List: Exercise - 47 with Solution
Write a Python program to insert an element before each element of a list.
Sample Solution:
Python Code:
# Define a list 'color' containing color names
color = ['Red', 'Green', 'Black']
# Print the original list 'color'
print("Original List: ", color)
# Use a list comprehension to create a new list 'color' by inserting the letter 'c' before each element in the original list
# This results in each color name being duplicated with 'c' added in front of it
# Print the updated list 'color'
color = [v for elt in color for v in ('c', elt)]
print("Updated List: ", color)
Sample Output:
Original List: ['Red', 'Green', 'Black'] Updated List: ['c', 'Red', 'c', 'Green', 'c', 'Black']
