'insert list in multilayer list in python
I have a code like:
a = ['layer 1', 2, ['layer 2', 22, ['layer 3', 222]]]
and I want using insert method add the following list ['layer 4', 2222, 3333] into index 1st of layer 3rd list
what I want is:
['layer 1', 2, ['layer 2', 22, ['layer 3', ['layer 4', 2222, 3333], 222]]]

Fairly straightforward indexing leads to this:
a = ['layer 1', 2, ['layer 2', 22, ['layer 3', 222]]]
b = ['layer 4', 2222, 3333]
a[-1][-1].insert(1, b)
print(a)
Output:
['layer 1', 2, ['layer 2', 22, ['layer 3', ['layer 4', 2222, 3333], 222]]]
Solution 2:[2]
You have to insert it into the inner list. The inner list is accessed via index:
a = ['layer 1', 2, ['layer 2', 22, ['layer 3', 222]]]
b = ['layer 4', 2222, 3333]
a[2][2].insert(1, b)
