[Enhancement] newline argument for csv.reader()

[opk12]

Current problem

The doc for csv.reader() warns that not passing newline can cause issues.

A csvfile is most commonly a file-like object or list. If csvfile is a file object, it should be opened with newline=''

If newline='' is not specified, newlines embedded inside quoted fields will not be interpreted correctly, and on platforms that use \r\n linendings on write an extra \r will be added. It should always be safe to specify newline='', since the csv module does its own (universal) newline handling.

Desired solution

Warn if csv.reader() is not being passed newline explicitly.

Additional context

I found this in a student homework. Is it in-scope for pylint to warn? Note that refurb did not warn.

import csv
result = {}

def f():
    with open("/tmp/file1", 'r') as route:
        for row in csv.reader(route, delimiter="\t"):
            counter = counter + 1
            result[row[0]] = row[1]
        ...
    return counter

f()
