What are the differences between map and for loop in Python?
The main difference is that map
applies a function to all items in an iterable, while a for
loop iterates through items.
Can you give me an example of both?
Sure! For map
, you can use map(lambda x: x*2, [1, 2, 3])
, and for a for
loop: for x in [1, 2, 3]: print(x*2)
.
Which one is more efficient?
map
can be more efficient for large datasets since it's implemented in C, but readability is also important.
When should I use one over the other?
Use map
for cleaner, functional-style code when applying a function, and for
loops for more complex operations.
