如何在不导入其他模块的情况下更改 python 中文本的颜色？
How do you change the colour of text in python without importing other modules?
如何创建打印语句，例如 print("Hello world") 可能是不同颜色（例如绿色）。
另外，有没有不需要下载新模块的方法？
@epicgamer300065，以下所有代码均来自@Brian 和我 (@Scott) 之前提供的链接。我确实需要在导入后立即插入一个 init() 语句以使代码正常工作，并且我确实需要从命令提示符 运行 执行此操作（但不需要管理员权限），但它确实会产生预期的彩色结果。 （仅供参考，我在 win10pro 上使用 Python 3.8.1）：

print(Fore.RED + Back.GREEN + 'some red text')
print(Back.GREEN + 'and with a green background')
print(Style.BRIGHT + 'and in bright text')
print(Style.RESET_ALL)
print('back to normal now')
print(colored('Hello, World!', 'green', 'on_red'))

@epicgamer300065，这是一个实际的完整 IDLE 解决方案，适用于我在 win10pro 上使用 Python 3.8.1，但它在终端中不起作用。
它来自 idlecolors，由于您的访问受限，我已将 idlecolors.py 所需的完整模块包含在此处，以便您 copy/paste 避免无法安装。
如您所见，唯一的依赖项是模块 sys 和 random，但是 random 仅用于 randcol() 函数，您可以在没有 if 的情况下使用你必须这样做。
这是idlecolors.py：
import sys
import random
# This will only work in IDLE, it won't work from a command prompt
try:
shell_connect = sys.stdout.shell
except AttributeError:
print("idlecolors highlighting only works with IDLE")
exit()
# Map the colour strings to IDLE highlighting
USE_CUSTOM_COLORS = False # Change to True if you want to use custom colours
global colormap
if USE_CUSTOM_COLORS:
colormap = {"red": "COMMENT",
"orange": "KEYWORD",
"green": "STRING",
"blue": "stdout",
"purple": "BUILTIN",
"black": "SYNC",
"brown": "console",
"user1": "DEFINITION",
"user2": "sel",
"user3": "hit",
"user4": "ERROR",
"user5": "stderr"}
else:
colormap = {"red": "COMMENT",
"orange": "KEYWORD",
"green": "STRING",
"blue": "stdout",
"purple": "BUILTIN",
"black": "SYNC",
"brown": "console"}
# ---------------------------
# Functions
# ---------------------------
# Like the print() function but will allow you to print colours
def printc(text, end="\n"):
# Parse the text provided to find {text:color} and replace with the colour. Any text not encompassed in braces
# will be printed as black by default.
buff = ""
for char in text:
if char == "{":
# Write current buffer in black and clear
shell_connect.write(buff, colormap["black"])
buff = ""
elif char == "}":
# Write current buffer in color specified and clear
tag_write = buff.split(":")
shell_connect.write(tag_write[0], tag_write[1])
buff = ""
else:
# Add this char to the buffer
buff += char
# Write the chosen end character (defaults to newline like print)
sys.stdout.write( end )
# Individual colour functions
def red(text):
return "{"+ text + ":" + colormap["red"] + "}"
def orange(text):
return "{"+ text + ":" + colormap["orange"] + "}"
def green(text):
return "{"+ text + ":" + colormap["green"] + "}"
def blue(text):
return "{"+ text + ":" + colormap["blue"] + "}"
def purple(text):
return "{"+ text + ":" + colormap["purple"] + "}"
def black(text):
return "{"+ text + ":" + colormap["black"] + "}"
def brown(text):
return "{"+ text + ":" + colormap["brown"] + "}"
def randcol(text):
color = random.choice(list(colormap.keys()))
return "{"+ text + ":" + colormap[color] + "}"
# User defined colours
def user1(text):
return "{"+ text + ":" + colormap["user1"] + "}"
def user2(text):
return "{"+ text + ":" + colormap["user2"] + "}"
def user3(text):
return "{"+ text + ":" + colormap["user3"] + "}"
def user4(text):
return "{"+ text + ":" + colormap["user4"] + "}"
def user5(text):
return "{"+ text + ":" + colormap["user5"] + "}"
下面是您将如何使用它：
from idlecolors import *
printc( red("Red text") )
printc( "If you add " + red("red") + " to " + blue("blue") + ", you get " + purple("purple") )
# Print a line in a random colour
printc( randcol("This is a random colour") )
# Print each word in a random colour
mytext = "This is a random piece of text which I want to print in random colours"
mytext = mytext.split(" ")
for word in mytext:
printc(randcol(word), end=" ")
可用的颜色有 red()、orange()、green()、blue()、purple()、black()、brown() , 您可以使用 randcol() 从该选择中随机选择颜色。
如何创建打印语句，例如 print("Hello world") 可能是不同颜色（例如绿色）。
