Rename method "Read" to prevent any misunderstanding/clash with method "read" defined on line 582 Open
def Read(self, response):
- Read upRead up
- Exclude checks
Looking at the set of methods and fields in a class
and finding two that differ only by capitalization is confusing to users of the
class.
This situation may simply indicate poor naming. Method names should be action-oriented, and thus contain a verb, which is unlikely in the case where both a method and a field have the same name (with or without capitalization differences). However, renaming a public method could be disruptive to callers. Therefore renaming the member is the recommended action.
Noncompliant Code Example
class SomeClass: lookUp = false def lookup(): # Non-compliant; method name differs from field name only by capitalization pass
Compliant Solution
class SomeClass: lookUp = false def getLookUp(): pass
Refactor this function to reduce its Cognitive Complexity from 21 to the 15 allowed. Open
def do_exit(self, argv):
- Read upRead up
- Exclude checks
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.

Remove this commented out code. Open
# validator = self._set_HTTP_header
- Read upRead up
- Exclude checks
Programmers should not comment out code as it bloats programs and reduces readability.
Unused code should be deleted and can be retrieved from source control history if required.

Merging collapsible if
statements increases the code's readability.
Noncompliant Code Example
if condition1: if condition2: # ...

Rename function "updateStatus" to match the regular expression ^[a-z_][a-z0-9_]{2,}$. Open
def updateStatus(curReqNum):
- Read upRead up
- Exclude checks
Shared coding conventions allow teams to collaborate efficiently. This rule checks that all function names match a provided regular expression.
Noncompliant Code Example
With the default provided regular expression: ^[a-z_][a-z0-9_]{2,30}$
def MyFunction(a,b): ...
Compliant Solution
def my_function(a,b): ...
Either merge this branch with the identical one on line "182" or change one of the implementations. Open
self[key] = value
- Read upRead up
- Exclude checks
Having two branches in the same if
structure with the same implementation is at best duplicate code, and at worst a coding error. If
the same logic is truly needed for both instances, then they should be combined.
Noncompliant Code Example
if 0 <= a < 10: do_the_thing() elif 10 <= a < 20: do_the_other_thing() elif 20 <= a < 50: do_the_thing() # Noncompliant; duplicates first condition else: do_the_rest() b = 4 if a > 12 else 4
Compliant Solution
if (0 <= a < 10) or (20 <= a < 50): do_the_thing() elif 10 <= a < 20: do_the_other_thing() else: do_the_rest() b = 4
or
if 0 <= a < 10: do_the_thing() elif 10 <= a < 20: do_the_other_thing() elif 20 <= a < 50: do_the_third_thing() else: do_the_rest() b = 8 if a > 12 else 4
