为什么在使用Python3 print（）输出包含'\r'的字符串时会得到不同的结果？

Question

环境是python3.6和win10x64。 我想用print()输出字符串'123456\rabc'，正确的结果应该是'abc456'，但是我得到了不同的答案。你知道吗

    print('123456\rabc')

I run the file test.py, and the result was this:

    123456
    abc

I still run test.py, the result was:

    C:\Users\user\Anaconda3\python.exe C:/Users/user/Desktop/cv/test.py
abc

    Process finished with exit code 0

所以我不知道为什么这些结果不同。你知道吗
