# 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]
```
