Nested ``if``, ``for``, ``while``, ``try``, and ``with`` statements are key ingredients for making what's known as "Spaghetti code". Such code is hard to read, refactor and therefore maintain.
== Noncompliant Code Example
The following code snippet illustrates this rule with the default threshold of 3.
----
if condition1: # Compliant - depth = 1
# ...
if condition2: # Compliant - depth = 2
for i in range(10): # Compliant - depth = 3, not exceeding the limit
if condition4: # Non-Compliant - depth = 4
if condition5: # Depth = 5, exceeding the limit, but issues are only reported on depth = 4
