Advantages of a Dictionary vs a 2 dimensional list in Python
Advantages of a Dictionary vs a 2 dimensional list in Python Do the Python Course Clear meaning with keys (readability) Dictionary values are accessed using descriptive keys . 2D lists rely on index positions , which are harder to remember. # Dictionary: student["age"] # 2D list: student[1][2] ### What does this mean?student["age"] Do the Python Course Faster data access Dictionaries use hashing , giving near O(1) lookup time. 2D lists require searching , which is slower (O(n)). Flexible structure Dictionaries allow adding/removing items without breaking structure. 2D lists require strict ordering and consistent indexing. No wasted space Dictionaries store only existing key-value pairs. 2D lists may contain empty or unused positions. Better for real-world data Real data is often named , not numbered.
