Question

我是python的新手，大约一个月的学习时间。我遇到了一个问题，当我运行此代码时，它应该打印出红色的数字。第二个例子显示了它真正打印出来的东西，我被卡住了。请帮忙。

它应该打印('Enemy HP:', 1150/1200)
但它实际打印('Enemy HP:', '\x1b[91m1150/1200\x1b[0m\n')

import random

class bcolors:
    HEADER = '\033[95m'
    OKBLUE = "\x1b[94m"
    OKGREEN = "\x1b[92m"
    WARNING = '\033[93m'
    FAIL = '\x1b[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'

Answer 1

您的代码在Python 3中运行良好，其中print是一个函数：

>>> print("x", "y")
x y

这意味着＆＃34;打印第一个参数，然后是分隔符（默认为空格），然后是第二个参数。

在Python 2中，但是：

>>> print("x", "y")
('x', 'y')

打印包含字符串的元组的表示。

因此，您可以使用具有许多优点的Python 3，也可以更改您的代码：

print("Enemy HP:" + bcolors.FAIL + str(enemy.get_hp()) + "/" +  
      str(enemy.get_max_hp()) + bcolors.ENDC + "\n")
# note the + instead of ,

为了打印单个字符串。

Answer 2

它适用于你的其他人吗？

你有一个双引号＆＃34;＆＃34;相反，简单的＆＃39;＆＃39;在类bcolors中的OKGREEN可能它来自这里
