PyChecker is a tool for finding bugs in python source code. It finds
|
|
problems that are typically caught by a compiler for less dynamic
|
|
languages, like C and C++. It is similar to lint. Because of the
|
|
dynamic nature of python, some warnings may be incorrect; however,
|
|
spurious warnings should be fairly infrequent.
|
|
|
|
PyChecker works in a combination of ways. First, it imports
|
|
each module. If there is an import error, the module cannot be
|
|
processed. The import provides some basic information about the
|
|
module. The code for each function, class, and method is checked for
|
|
possible problems.
|
|
|
|
Types of problems that can be found include:
|
|
* No global found (e.g., using a module without importing it)
|
|
* Passing the wrong number of parameters to functions, methods,
|
|
constructors
|
|
* Passing the wrong number of parameters to builtin functions & methods
|
|
* Using format strings that don't match arguments
|
|
* Using class methods and attributes that don't exist
|
|
* Changing signature when overriding a method
|
|
* Redefining a function/class/method in the same scope
|
|
* Using a variable before setting it
|
|
* self is not the first parameter defined for a method
|
|
* Unused globals and locals (module or variable)
|
|
* Unused function/method arguments (can ignore self)
|
|
* No doc strings in modules, classes, functions, and methods
