How to Reverse List and Print without brackets and commas in Python
Lists are one kind of datatypes that is used to store various items in a single variable. Lists in usually look like this :
list=[1,2,3,4,5]
Reverse a List
There are multiple ways to reverse a list.
- with reversed() function
- with reverse() function
- using slicing
The problem arises when we try to print it after done with reversing. The given example below will show you how you can print a reversed list without the brackets or commas of the original list.
Reverse with reversed() function
The reversed() function returns an iterator that can access the elements in reverse order.
List_1 = [1, 2, 4, 3, 5]
a=reversed(List_1)
print(*a)
Output:
5 3 4 2 1
Reverse with reverse() function
The reverse() function won't return any value but will update the existing elements of the list.
list_2=[4,5,6,7,8,9]
list_2.reverse()
print(*list_2, sep=" ")
Output:
9 8 7 6 5 4
Without the separator, the answer is also the same.
Reverse using slice
In Python, variable[::-1] means, the elements of the list will be gone through starting from last and it will step backward one step at a time.
list_3 = [3,4,5,6,7]
reversed_list = list_3[::-1]
print(*reversed_list)
Output
7 6 5 4 3
