python – 如何从单个脚本中打开两个控制台

除了脚本自己的控制台(什么都不做)我想打开两个控制台并在不同的控制台中打印变量con1和con2,我怎样才能实现这一点.

con1 = 'This is Console1'
con2 = 'This is Console2'

我不知道如何实现这一点,花了几个小时尝试使用子进程等模块,但没有运气.顺便说一句,我在窗户上.

编辑:

线程模块会完成这项工作吗?或者需要多处理?

例如:

如果你不想像 reconsider your problem and use a GUI这样的 reconsider your problem and use a GUI那么你可以使用子进程模块同时启动两个新的控制台并在打开的窗口中显示两个给定的字符串:

#!/usr/bin/env python3
import sys
import time
from subprocess import Popen, PIPE, CREATE_NEW_CONSOLE

messages = 'This is Console1', 'This is Console2'

# open new consoles
processes = [Popen([sys.executable, "-c", """import sys
for line in sys.stdin: # poor man's `cat`
    sys.stdout.write(line)
    sys.stdout.flush()
"""],
    stdin=PIPE, bufsize=1, universal_newlines=True,
    # assume the parent script is started from a console itself e.g.,
    # this code is _not_ run as a *.pyw file
    creationflags=CREATE_NEW_CONSOLE)
             for _ in range(len(messages))]

# display messages
for proc, msg in zip(processes, messages):
    proc.stdin.write(msg + "\n")
    proc.stdin.flush()

time.sleep(10) # keep the windows open for a while

# close windows
for proc in processes:
    proc.communicate("bye\n")

这是一个不依赖于CREATE_NEW_CONSOLE的简化版本:

#!/usr/bin/env python
"""Show messages in two new console windows simultaneously."""
import sys
import platform
from subprocess import Popen

messages = 'This is Console1', 'This is Console2'

# define a command that starts new terminal
if platform.system() == "Windows":
    new_window_command = "cmd.exe /c start".split()
else:  #XXX this can be made more portable
    new_window_command = "x-terminal-emulator -e".split()

# open new consoles, display messages
echo = [sys.executable, "-c",
        "import sys; print(sys.argv[1]); input('Press Enter..')"]
processes = [Popen(new_window_command + echo + [msg])  for msg in messages]

# wait for the windows to be closed
for proc in processes:
    proc.wait()
