python range reverse
When you call range() with three arguments, you can choose not only
where the series of numbers will start and stop but also how big the
difference will be between one number and the next.
range(start, stop, step)
If your 'step' is negative and 'start' is bigger than 'stop', then
you move through a series of decreasing numbers.
for i in range(10,0,-1):
print(i, end=' ')
# Output: 10 9 8 7 6 5 4 3 2 1
reverse for loop python
# 1.
for i in reversed(range(3)): # output: 0
print(i) # 1
# 2
# works with arrays as well , reversed(arr)
# 2.
# another alternative is
arr = [1,2,3]
# note: arr[start : end : step]
for i in arr[::-1]: # output: 0
print(i) # 1
# 2
# 3.
# last alternative i don't recommened!
# note: range(start, end, step)
for i in range(len(arr) - 1, -1 , -1): # output: 0
print(i) # 1
# 2
# read more on range() to understand even better how it works has the same rules as the arrays
python iterate backwards through list
>>> a = ["foo", "bar", "baz"]
>>> for i in reversed(a):
... print(i)
...
or
>>> for i, e in reversed(list(enumerate(a))):
... print(i, e)
reverse function python
# The Reverse operation - Python 3:
Some_List = [1, 2, 3, 4, 1, 2, 6]
Some_List.reverse()
print(Some_List)
# Result: [6, 2, 1, 4, 3, 2, 1]
reverse() in python
# Operating System List
systems = ['Windows', 'macOS', 'Linux']
print('Original List:', systems)
# List Reverse
systems.reverse()
# updated list
print('Updated List:', systems)
