No encoding specified for file

Last modified: 03 December 2024

Reports a missing encoding comment in Python 2.

Example:

class Book(object):
    def __init__(self):
        pass

When the quick-fix is applied, the missing comment is added:

# coding=utf-8
class Book(object):
    def __init__(self):
        pass
