Python: Initialize and fills a list with the specified value
Python List: Exercise - 251 with Solution
Write a Python program that fills a list with the specified value.
- Use a list comprehension and range() to generate a list of length equal to n, filled with the desired values.
- Omit val to use the default value of 0.
Sample Solution:
Python Code:
def initialize_list_with_values(n, val = 0):
return [val for x in range(n)]
print(initialize_list_with_values(7))
print(initialize_list_with_values(8,3))
print(initialize_list_with_values(5,-2))
print(initialize_list_with_values(5, 3.2))
Sample Output:
[0, 0, 0, 0, 0, 0, 0] [3, 3, 3, 3, 3, 3, 3, 3] [-2, -2, -2, -2, -2] [3.2, 3.2, 3.2, 3.2, 3.2]
