Pylint showing invalid variable name in output
pylint, python
Solution
As your code is not contained in a class or function it is expecting those variables to be constants and as such they should be uppercase.
You can read PEP8 for further information.
Problem
I made a simple python script to post data on a website. ``` #Imports url_to_short = sys.argv[1] post_url = 'https://www.googleapis.com/urlshortener/v1/url' headers = {'Content-Type': 'application/json'} data = {'longUrl': url_to_short} post_data = json.dumps(data) req = urllib2.Request(post_url, post_data, headers) resp = urllib2.urlopen(req) if resp.getcode() == 200: content = json.loads(resp.read()) #Other stuff ``` Now I thought lets check my script for coding standards with `pylint` tool. My `pylint` output is as follows: ``` ************* Module post C: 1,0: Missing docstring C: 6,0: Invalid name "url_to_short" (should match (([A-Z_][A-Z0-9_]*)|(__.*__))$) C: 8,0: Invalid name "post_url" (should match (([A-Z_][A-Z0-9_]*)|(__.*__))$) C: 9,0: Invalid name "headers" (should match (([A-Z_][A-Z0-9_]*)|(__.*__))$) # Other stuff ``` Now, my question is why `pylint` is showing my variable names as `Invalid name`. Is naming variable this way a wrong coding convention. My complete pylint output.
