Why are nested if statements Bad?

Why This is Bad Deeply nested conditionals make it just about impossible to tell what code will run, or when. The big problem with nested conditionals is that they muddy up code’s control flow: in other words, they make it just about impossible to tell what code will run, or when.

When you code an if statement within another if statement The statements are nested?

How do you use multiple if in Python?

Python supports multiple independent conditions in the same if block. Say you want to test for one condition first, but if that one isn’t true, there’s another one that you want to test. Then, if neither is true, you want the program to do something else. There’s no good way to do that using just if and else .
