在类python和kivy中打印彩色字符串

Question

无类编码

import sys
from termcolor import colored
string="admin"
lista=["W","W","W","W","G"]
string1=""
for i in range(5):
if lista[i]=="W":
string1+=colored(string[i],'red')
elif lista[i]=="G":
string1+=colored(string[i],'green')
else:
string1+=colored(string[i],'blue')
print(string1)

有了这个代码，我可以打印出特定颜色的字母，这取决于相应索引中的列表变量。但是：

主要关注.py文件中的函数ShowPreviousWord，在函数的开头(开始时，放上5个字母中的最后一个(，它被赋予一个要打印的字符串，颜色列表从不同的函数传递。它的代码与没有类的代码完全相同，但是print并没有给出相同的结果。

例如，对于单词"；管理员"；列表=["W"，"W"、"W">←[37ma←[0m←[37md←[0m←[37毫米←[0m←[37英里←[0m←[3200万←[0m

同时，第一个代码按照我的意愿工作。为了增加问题，我想把彩色字符串传递给kivy标签，并在屏幕上显示它。为什么它不起作用？

Answer 1

此处使用Label的markup道具进行着色。以及使用新功能设置颜色(十六进制(。

首先定义一个用于设置颜色(color(的函数为，

def set_color(letter, color):
COLORS_DICT  = {"W" : "ffffff", "Y" : "ffff00", "G" : "00ff00"}
c = COLORS_DICT.get(color, "W")
return f"[color={c}]{letter}[/color]"

现在在方法ShowPreviousWord中使用它作为，

def ShowPreviousWord(self):
...
print(string)
print(self.accuratecolor)
coloredstring = "".join((set_color(l, c) for l, c in zip(string, self.accuratecolor)))
print(coloredstring)
...

最后，激活Label中的markup进行渲染，

Label:
pos_hint:{'center_x':0.2,'y':-0.35}
id:ATTEMPTS
markup: True
