Nested if statements can be collapsed into a single if statement by separating their condition using and operator. Merging collapsible if statements increases the code's readability.

Bad practice

if condition1:
    if condition2:
        dosomething()

Preferred

if condition1 and condition2:
    dosomething()

Exception:

DeepSource will not raise this issue when the nested if statements have comments in between them, as it could be explaining why the nested if is in place.
