最简单的方法是像这样对powershell进行系统调用:

s=os.system('powershell Write-Host "I am so bored with this. Work already" -ForegroundColor Blue')

否则:

←[94mPff

在powershell中为日志语句设置颜色并不是什么大问题。 你可以使用-ForegroundColor参数。

写一个确认消息。

Write-Host "Process executed Successfully...." -ForegroundColor Magenta

写入错误消息。

Write-Host "Sorry an unexpected error occurred.." -ForegroundColor Red

写一个进度消息。

Write-Host "Working under pocess..." -ForegroundColor Green

我看这个是因为我想在Win7批处理文件中引入一些简单的文本颜色。这是我想到的。谢谢你的帮助。

@echo off
cls && color 08

rem .... the following line creates a [DEL] [ASCII 8] [Backspace] character to use later
rem .... All this to remove [:]
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (set "DEL=%%a")

echo.

<nul set /p="("
call :PainText 09 "BLUE is cold"    && <nul set /p=")  ("
call :PainText 02 "GREEN is earth"  && <nul set /p=")  ("

goto :end

自Windows XP以来，通过使用PowerShell作为通过命名管道链接到控制台输出的子进程，可以快速有效地用cmd批处理着色。这也可以用FindStr来完成，但是PowerShell提供了更多的选项，而且似乎更快。

保持PowerShell为子进程，使用管道进行通信的主要好处是，显示要比为每一行显示启动PowerShell或FindStr快得多。

其他优点:

不需要临时文件 通过管道进行回显允许显示完整的ASCII表而不需要转义。 与fd重定向工作良好。以stderr为例，或者重定向到一个文件/其他进程。

下面是一个示例代码:

::
:: Launch a PowerShell child process in the background linked to the console and 
:: earing through named pipe PowerShellCon_%PID%
::
:: Parameters :
::   [ PID ] : Console Process ID used as an identifier for the named pipe, launcher PID by default.
::   [ timeout ] : Subprocess max life in seconds, 300 by default. If -1, the subprocess
::                  will not terminate while the process %PID% is still alive.
:: Return :
::   0 if the child PowerShell has been successfully launched and the named pipe is available.
::   1 if it fails.
::   2 if we can't get a PID.
::   3 if PowerShell is not present or doesn't work.

Solution for changing the foreground and background colors and writing without new lines. It does not create any temporary files. No special editors are required, so Notepad can be used for editing. The first parameter for the :color subroutine is the color code, the rest of the (optional) parameters are the text to display. If the last parameter is $ then a new line is written at the end. The color codes are the same as for the color command. The :echo subroutine can be used to display a text without new line (unlike regular echo).

@echo off

I'm adding an answer to address an issue noted in some comments above: that inline ansi color codes can misbehave when inside a FOR loop (actually, within any parenthesized block of code). The .bat code below demonstrates (1) the use of inline color codes, (2) the color failure that can occur when inline color codes are used in a FOR loop or within a parenthesized block of code, and (3) a solution to the problem. When the .bat code executes, tests 2 and 3 demonstrate the colorcode failure, and test 4 shows no failure because it implements the solution.

[编辑2020-04-07:我发现了另一个解决方案，可能比调用子例程更有效。将FINDSTR短语括在括号中，如下所示:

   echo success | (findstr /R success)

ENDEDIT]

注意:根据我的(有限的)经验，颜色代码问题只有在输入被管道输送到代码块中的FINDSTR之后才会出现。这就是下面的.bat重现问题的方式。颜色代码问题可能比输送到FINDSTR之后更普遍。如果有人能解释问题的本质，如果有更好的解决方法，我会很感激。

@goto :main
:resetANSI
EXIT /B
rem  The resetANSI subroutine is used to fix the colorcode
rem  bug, even though it appears to do nothing.

:main
@echo off
setlocal EnableDelayedExpansion

rem  Define some useful colorcode vars:
for /F "delims=#" %%E in ('"prompt #$E# & for %%E in (1) do rem"') do set "ESCchar=%%E"
set "green=%ESCchar%[92m"
set "yellow=%ESCchar%[93m"
set "magenta=%ESCchar%[95m"
set "cyan=%ESCchar%[96m"
set "white=%ESCchar%[97m"
set "black=%ESCchar%[30m"

echo %white%Test 1 is NOT in a FOR loop nor within parentheses, and color works right.
   echo %yellow%[Test 1] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.%yellow%
   echo %green%This is green.
echo %cyan%Test 1 completed.

echo %white%Test 2 is within parentheses, and color stops working after the pipe to FINDSTR.
(  echo %yellow%[Test 2] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 2 completed.

echo %white%Test 3 is within a FOR loop, and color stops working after the pipe to FINDSTR.
for /L %%G in (3,1,3) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 3 completed.

echo %white%Test 4 is in a FOR loop but color works right because subroutine :resetANSI is 
echo called after the pipe to FINDSTR, before the next color code is used.
for /L %%G in (4,1,4) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   call :resetANSI
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.
   echo %green%This is green.
)
echo %cyan%Test 4 completed.%white%

EXIT /B
