Try this:
Use with AI[(i, j) for i, j in enumerate(mylist)]
You need to put i,j inside a tuple for the list comprehension to work. Alternatively, given that enumerate() already returns a tuple, you can return it directly without unpacking it first:
Use with AI[pair for pair in enumerate(mylist)]
Either way, the result that gets returned is as expected:
Use with AI> [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

Python enumerate(): Simplify Loops That Need Counters – Real Python
June 23, 2025 - >>> values = ["first", "second"] >>> enumerate_instance = enumerate(values) >>> print(enumerate_instance) <enumerate at 0x7fe75d728180> >>> next(enumerate_instance) (0, 'first') >>> next(enumerate_instance) (1, 'second') >>> next(enumerate_instance) Traceback (most recent call last): File "<python-input-5>", line 1, in <module> next(enumerate_instance) ~~~~^^^^^^^^^^^^^^^ StopIteration · In this example, you create a Python list called values with two elements, "first" and "second".

In short: enumerate adds a counter to an iterable and you can give an optional parameter (default: 0) where to start to count. Example: letters = ['a', 'b', 'c', 'd', 'e', 'f'] for counter, item in enumerate(letters, start=3): print(counter, item) output: (3, 'a') (4, 'b') (5, 'c') (6, 'd') (7, 'e') (8, 'f') More on reddit.com

I believe it's because enurmate is a generator (not sure about that) but to use it you do this. for index, value in enurmate(planets): Then it will return the index and the value for every item in planets

Just to be really clear, this has nothing to do with enumerate and everything to do with list comprehension syntax.
This list comprehension returns a list of tuples:
Use with AI[(i,j) for i in range(3) for j in 'abc']
this a list of dicts:
Use with AI[{i:j} for i in range(3) for j in 'abc']
a list of lists:
Use with AI[[i,j] for i in range(3) for j in 'abc']
a syntax error:
Use with AI[i,j for i in range(3) for j in 'abc']
Which is inconsistent (IMHO) and confusing with dictionary comprehensions syntax:
Use with AI>>> {i:j for i,j in enumerate('abcdef')}
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f'}
And a set of tuples:
Use with AI>>> {(i,j) for i,j in enumerate('abcdef')}
set([(0, 'a'), (4, 'e'), (1, 'b'), (2, 'c'), (5, 'f'), (3, 'd')])
As Óscar López stated, you can just pass the enumerate tuple directly:
Use with AI>>> [t for t in enumerate('abcdef') ]
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f')]
