Simple Python class to create colored messages for command line printing

bcolors.py

# Helper class to print colored output
#
# To use code like this, you can do something like
# 
# print bcolors.WARNING
#       + "Warning: No active frommets remain. Continue?" 
#       + bcolors.ENDC
#
# you can also use the convenience method bcolors.colored like this
# 
# print(bcolors.colored("This frumble is underlined", bcolors.UNDERLINE))
# 
# or use one of the following convenience methods
#   warning, fail, ok, okblue, header
#
# like this
# 
# print(bcolors.warning("This is dangerous"))
#
# Method calls can be nested too, pritn an underlined header do this:
# 
# print(bcolors.header(bcolors.colored("The line under this text is purple too ... ", bcolors.UNDERLINE)))

class bcolors:
    HEADER    = '\033[95m'
    OKBLUE    = '\033[94m'
    OKGREEN   = '\033[92m'
    WARNING   = '\033[93m'
    FAIL      = '\033[91m'
    BOLD      = '\033[1m'
    UNDERLINE = '\033[4m'
    ENDC      = '\033[0m'

    # Method that returns a message with the desired color
    # usage:
    #    print(bcolor.colored("My colored message", bcolor.OKBLUE))
    @staticmethod
    def colored(message, color):
      return color + message + bcolors.ENDC

    # Method that returns a yellow warning
    # usage:
    #   print(bcolors.warning("What you are about to do is potentially dangerous. Continue?"))
    @staticmethod
    def warning(message):
      return bcolors.WARNING + message + bcolors.ENDC

    # Method that returns a red fail
    # usage:
    #   print(bcolors.fail("What you did just failed massively. Bummer"))
    #   or:
    #   sys.exit(bcolors.fail("Not a valid date"))
    @staticmethod
    def fail(message):
      return bcolors.FAIL + message + bcolors.ENDC

    # Method that returns a green ok
    # usage:
    #   print(bcolors.ok("What you did just ok-ed massively. Yay!"))
    @staticmethod
    def ok(message):
      return bcolors.OKGREEN + message + bcolors.ENDC

    # Method that returns a blue ok
    # usage:
    #   print(bcolors.okblue("What you did just ok-ed into the blue. Wow!"))
    @staticmethod
    def okblue(message):
      return bcolors.OKBLUE + message + bcolors.ENDC

    # Method that returns a header in some purple-ish color
    # usage:
    #   print(bcolors.header("This is great"))
    @staticmethod
    def header(message):
      return bcolors.HEADER + message + bcolors.ENDC

Does this class support Python 2.7?
I am trying to see if using this class would work for me, but it fails for each function I tried with the same error.
I have provided an example below...

For example if you have created a python file as bcolors.py, try as such snowman11784

from bcolors import bcolors
print(bcolors.warning("This is dangerous"))

You should import the class bcolors from the module (in your case also called bcolors because the file is also called that way):

>>> from bcolors import bcolors

This is dangerous
