The input method in Python 2 will read from standard input, evaluate and run the resulting string as python source code. This is similar, though in many ways worse, then using eval. On Python 2, use raw_input instead, input is safe in Python 3.

Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

A method's cognitive complexity is based on a few simple rules:

  • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
  • Code is considered more complex for each "break in the linear flow of the code"
  • Code is considered more complex when "flow breaking structures are nested"

Cognitive Complexity is a measure of how hard the control flow of a function is to understand. Functions with high Cognitive Complexity will be difficult to maintain.

Using the same value on either side of a binary operator is almost always a mistake. In the case of logical operators, it is either a copy/paste error and therefore a bug, or it is simply wasted code, and should be simplified. In the case of bitwise operators and most binary mathematical operators, having the same value on both sides of an operator yields predictable results, and should be simplified.

This rule ignores *, +, and =.

Noncompliant Code Example

if a == a: # Noncompliant
    work()

if  a != a: # Noncompliant
    work()

if  a == b and a == b: # Noncompliant
    work()

if a == b or a == b: # Noncompliant
    work()

j = 5 / 5 # Noncompliant
k = 5 - 5 # Noncompliant

Exceptions

The following are ignored:

  • The expression 1 << 1
