How to represent the name of a variable in batches in python?

I have many lists ,which are named like a+str(i), such as a0. I want to add the two adjacent ones in turn.

a0=['a']
a1=['k']
a2=['e','a']
a3=['k','e']

a0=a0+a1
a1=a1+a2
a2=a2+a3

I want to know whether there are a way to represent the name of the list in batches in python.

I expect to use a for loop to express.

Expected:

for i in range(1,4):
    ai= ai + a(i-1)

Don't do that, use a dict instead. – Stephen Rauch Sep 25 '18 at 06:01
A `dict`? How to do it? – rosefun Sep 25 '18 at 06:03

You should make `a` a list of lists instead if the indexes are sequential: `a = [[i + 1] for i in range(4)]` – blhsing Sep 25 '18 at 06:03

@StephenRauch Exactly, I don't think that's a duplicate but that blhsing's comment is the answer (that doesn't exclude the possibility that this is a duplicate of another question though). – a_guest Sep 25 '18 at 06:04
Why can't you just use a list for the original values, where `i` is the index, e.g. `a = [1, 2, 3, 4]`? In this case, `a[2]` would equal 3. You could use a generator to modify the original values. – Alexander Sep 25 '18 at 06:04
@a_guest, the dict will accommodate the entirety of the OPs listed code. A list made be more appropriate but a dict will also work. – Stephen Rauch Sep 25 '18 at 06:07
