#Python #RemoveDuplicates #PythonList #PythonPrograms #PythonForBeginners #PythonPractice
Logic:
1. Suppose we have a list with repeated elements:
list1 = [1, 2, 2, 3, 4, 4, 5]
2. Goal → Remove duplicates → [1, 2, 3, 4, 5]
3. Approaches:
→ Method 1: Convert list into a set (since sets don’t allow duplicates)
Quick and easy but doesn’t preserve order.
→ Method 2: Use a loop and store unique elements in a new list
Preserves order.
→ Method 3: Use dict.fromkeys()
Removes duplicates and keeps order in Python 3.7+
Code:
Remove duplicates using set()
list1 = [1, 2, 2, 3, 4, 4, 5]
unique = list(set(list1))
print("List without duplicates:", unique)
Remove duplicates using loop
list1 = [1, 2, 2, 3, 4, 4, 5]
unique = []
for num in list1:
if num not in unique:
unique.append(num)
print("List without duplicates:", unique)
Remove duplicates using dict.fromkeys()
list1 = [1, 2, 2, 3, 4, 4, 5]
unique = list(dict.fromkeys(list1))
print("List without duplicates:", unique)
