Python: Initialize and fills a list with the specified value

Python List: Exercise - 251 with Solution

Write a Python program to initialize and 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]

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
