Python: Append the same value /a list multiple times to a list/list-of-lists

Python List: Exercise - 159 with Solution

Write a Python program to append the same value/a list multiple times to a list/list-of-lists.

Sample Solution:

Python Code:

print("Add a value(7), 5 times, to a list:")
nums = []
nums += 5 * ['7']
print(nums)
nums1 = [1,2,3,4]
print("\nAdd 5, 6 times, to a list:")
nums1 += 6 * [5]
print(nums1)
print("\nAdd a list, 4 times, to a list of lists:")
nums1 = []
nums1 += 4 * [[1,2,5]]
print(nums1)
print("\nAdd a list, 4 times, to a list of lists:")
nums1 = [[5,6,7]]
nums1 += 4 * [[1,2,5]]
print(nums1)

Sample Output:

Add a value(7), 5 times, to a list:
['7', '7', '7', '7', '7']

Add 5, 6 times, to a list:
[1, 2, 3, 4, 5, 5, 5, 5, 5, 5]

Add a list, 4 times, to a list of lists:
[[1, 2, 5], [1, 2, 5], [1, 2, 5], [1, 2, 5]]

Add a list, 4 times, to a list of lists:
[[5, 6, 7], [1, 2, 5], [1, 2, 5], [1, 2, 5], [1, 2, 5]]
