How to save current cmd-output-CodePudding

Is there a way to get whats currently displayed on the windows command prompt?

For example:

print('some text')
print('some different text')

>>> some text
>>> some different text

a = save_whats_on_cmd()
>>> a = 'some text \n some different text'

Create a file, let say mylib.py

import sys

class Logger(object):
    def __init__(self):
        self.terminal = sys.stdout
        self.log = open('log.dat', 'w')

    def write(self, message):
        self.terminal.write(message)
        self.log.write(message)

    def flush(self):
        pass

Then open your interpreter:

>>> from mylib import Logger
>>> import sys
>>> sys.stdout = Logger()
>>> print(1)
1
>>> print(2)
2
>>> print(3)
3
>>> exit()

See log.dat:

1
2
3

import sys
sys.stdout = open("test.txt", "w")
print("Hello World")
sys.stdout.close()

test.txt will have Hello World
