How to get a brief summary or exactly the number of errors and warnings using pylint in python -

how brief summary of pylint error messages or number of pylint errors, warnings, refactors using python code?

pylint -rn

this allows pylint output messages , excludes reports. have tried till :

lint_arg = "pylint -rn %s"%file_name pr = subprocess.popen( arg, cwd=os.path.dirname(lint_path), shell=true, stdout=subprocess.pipe, stderr=subprocess.pipe) (out, error) = pr.communicate() pylint_result = out + "\n" + error file=open("pylint_output",w) file.write(pylint_result) file.close()

i number of lines in errors, warnings occurred , move info string. thought below:

step 1 : run pylint in python script using subprocess.popen() step 2 : store output in file or variable . step 3: parse file , generate expected output below:

expected output : next file < filename> has : 5 warnings in line number : 11, 34 ,56 (lines in warnings occurred) 2 errors in line number :2 (lines in errors occurred).

how can help of pylint command s or utilize of python script? help appreciated. advance thanks.

first, don't utilize popen, quote pylint's docs:

to silently run pylint on module_name.py module, , standart output , error:

from pylint import epylint lint (pylint_stdout, pylint_stderr) = lint.py_run('module_name.py', true)

second, see output format, man pylint says:

using default text output, message format is:

message_type: line_num:[object:] message

assuming line line of pylint output, should gather need:

pylint_res = {'c': [], 'r': [], 'w': [], 'e': [], 'f': []} msg_type, lineno = line.split(':', 2)[:2] pylint_res[msg_type].append(lineno)

all need iterate on pylint's output, adding above pylint_res, , printing out results.
