Python: Create a shallow copy of a given list
Python module: Exercise-1 with Solution
Write a Python program to create a shallow copy of a given list. Use copy.copy
Sample Solution:
Python Code:
import copy
nums_x = [1, [2, 3, 4]]
print("Original list: ", nums_x)
nums_y = copy.copy(nums_x)
print("\nCopy of the said list:")
print(nums_y)
print("\nChange the value of an element of the original list:")
nums_x[1][1] = 10
print(nums_x)
print("\nSecond list:")
print(nums_y)
nums = [[1], [2]]
nums_copy = copy.copy(nums)
print("\nOriginal list:")
print(nums)
print("\nCopy of the said list:")
print(nums_copy)
print("\nChange the value of an element of the original list:")
nums[0][0] = 0
print("\nFirst list:")
print(nums)
print("\nSecond list:")
print(nums_copy)
Sample Output:
Original list: [1, [2, 3, 4]] Copy of the said list: [1, [2, 3, 4]] Change the value of an element of the original list: [1, [2, 10, 4]] Second list: [1, [2, 10, 4]] Original list: [[1], [2]] Copy of the said list: [[1], [2]] Change the value of an element of the original list: First list: [[0], [2]] Second list: [[0], [2]]

Python: Tips of the Day
Inverts a dictionary with non-unique hashable values:
Example:
def tips_collect_dictionary(obj): inv_obj = {} for key, value in obj.items(): inv_obj.setdefault(value, list()).append(key) return inv_obj ages = { "Owen": 25, "Jhon": 25, "Pepe": 15, } print(tips_collect_dictionary(ages))
Output:
{25: ['Owen', 'Jhon'], 15: ['Pepe']}
