Python类保持转义序列

Question

I have created simple class to keep escape seqs:

class Color:
    HEAD = '\033[95m'
    OKBL = '\033[94m'
    OKGR = '\033[92m'
    FAIL = '\033[93m'
    WARN = '\033[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDR = '\033[4m'

to use them in console outputs like so:

print(Color.WARN + "Output file will be overwritten!" + Color.ENDC)

now get message from linter that class has no __init__ method.

Is it OK and I can simply ignore this warning or what would be pythonic way here?

Answer 1

This would be the pythonic way to assign variables inside the class and access them outside.

class Color:
  def __init__(self):
    self.HEAD = '\033[95m'
    self.OKBL = '\033[94m'
    self.OKGR = '\033[92m'
    self.FAIL = '\033[93m'
    self.WARN = '\033[91m'
    self.ENDC = '\033[0m'
    self.BOLD = '\033[1m'
    self.UNDR = '\033[4m'

color = Color()
print(color.WARN + "Output file will be overwritten!" + color.ENDC)

__init__() method is used while creating an object from class. If you do not want to create any objects you do not have to define it. However, if you only want to it use to separate namespaces you could also simply move it to separate module.
