Hi Swadesmita,

There are a few differences between the 2 functions.

The reverse() function is an inplace method. It will change the orginal list and return None.

Whereas, the reversed function will return a reversed list and not change the original list.

To understand this better you can play around with the following code.


list1 = [0,1,2,3,4,5,6]

list1_reversed = reversed(list1)

print("list1 reversed output : ", list(list1_reversed))

print("list1 original : ", list1)

list1_reverse = list1.reverse()

print("list1 reversed output : ", list1_reverse)

print("list1 original : ", list1)

Hope this helps.

If you can’t see code block in the above post this is what it is supposed to be.

''list1 = [0,1,2,3,4,5,6]

list1_reversed = reversed(list1)

print("list1 reversed output : ", list(list1_reversed))

print("list1 original : ", list1)

list1_reverse = list1.reverse()

print("list1 reversed output : ", list1_reverse)

print("list1 original : ", list1)
