Try this:
[(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:
[pair for pair in enumerate(mylist)]
Either way, the result that gets returned is as expected:
> [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

March 2, 2022About iterating over a list of tuples
I'm not sure what you're asking. It's possible because the implementors of Python made it possible. The other syntax will also work of course, if you want the tuple as a whole, but anywhere you have multiple items you can always destructure them into individual variables. It's exactly the same as doing this for example: a, b = [1, 2] More on reddit.com

Python enumerate Function: Master Index-Based Iteration
The built-in enumerate() function in Python adds a counter to a sequence and returns the combination as an enumerate object. The enumerate() function takes a sequence like a list, tuple, or string, and returns an enumerate object.

Try this:

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:

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:
[(i,j) for i in range(3) for j in 'abc']
this a list of dicts:
[{i:j} for i in range(3) for j in 'abc']
a list of lists:
[[i,j] for i in range(3) for j in 'abc']
a syntax error:
[i,j for i in range(3) for j in 'abc']
Which is inconsistent (IMHO) and confusing with dictionary comprehensions syntax:
>>> {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:
>>> {(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:
>>> [t for t in enumerate('abcdef') ]
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f')]
