Hi all
After iterating over a sequence, the final element is still accessible.
In this case, the variable 'i' still references the integer 4.
Python 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 23:03:10) [MSC v.1916 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> for i in range(5):
... print(i)
...
0
1
2
3
4
>>> print(i)
4
>>>
Is this guaranteed in Python, or should it not be relied on?
If the latter, and you wanted to do something additional using the last
element, I assume that this would be the way to do it -
>>> for i in range(5):
... print(i)
... j = i
...
0
1
2
3
4
>>> print(j)
4
>>>
Alternatively, this also works, but is this one guaranteed?
>>> for i in range(5):
... print(i)
... else:
... print()
... print(i)
...
0
1
2
3
4
4
>>>
