🔁 Top 10 Python Dictionary Methods You Must Know 🧠📘

1. get() – Safely retrieve value by key

d.get('a')  # Returns value if key exists, otherwise None

2. keys() – Get all keys

d.keys()  # Returns dict_keys(['a', 'b'])

3. values() – Get all values

d.values()  # Returns dict_values([1, 2])

4. items() – Get key-value pairs

d.items()  # Returns dict_items([('a', 1), ('b', 2)])

5. update() – Merge another dictionary

d.update({'c': 3})  # Adds/updates keys: {'a':1, 'b':2, 'c':3}

6. pop() – Remove item by key

d.pop('a')  # Returns value and removes key 'a'

7. popitem() – Remove last inserted item

d.popitem()  # Returns (key, value) of last item

8. setdefault() – Get value or set default

d.setdefault('x', 0)  # Returns value or inserts 'x':0 if missing

9. clear() – Remove all items

d.clear()  # Results in empty dictionary {}

10. copy() – Create a shallow copy

new_d = d.copy()  # Copies dictionary without affecting original

🔁 Top 30 Python List Methods You Should Know

  🔁 Top 30 Python List Methods You Should Know 🧠📋 1. append() – Add element to the end lst = [ 1 , 2 ] lst.append( 3 ) # Output: [1, 2, 3] 2. extend() – Add multiple elements from another list lst = [ 1 , 2 ] lst.extend([ 3 , 4 ]) # Output: [1, 2, 3, 4] 3. insert() – Insert element at specific index lst = [ 1 , 3 ] lst.insert( 1 , 2 ) # Output: [1, 2, 3] 4. remove() – Remove first occurrence of a value lst = [ 1 , 2 , 3 ] lst.remove( 2 ) # Output: [1, 3] 5. pop() – Remove element at index (default last) lst = [ 1 , 2 , 3 ] lst.pop( 1 ) # Output: 2, list becomes [1, 3] 6. index() – Find index of first occurrence lst = [ 10 , 20 , 30 ] lst.index( 20 ) # Output: 1 7. count() – Count occurrences of value lst = [ 1 , 1 , 2 ] lst.count( 1 ) # Output: 2 8. sort() – Sort list in ascending order (in-place) lst = [ 3 , 1 , 2 ] lst.sort() # Output: [1, 2, 3] 9. reverse() – Reverse list (in-place) lst = [ 1 , 2 , 3 ] lst.reverse() # Output: [3, 2,...
