Can't follow the tutorial on windows

HI!
I am doing this tutorial, and BTW it is great. I could pass https://training.play-with-docker.com/beginner-linux with no problem.

I am using Windows 10's cmd, not the shell in right side of website.
I was doing https://training.play-with-docker.com/microservice-orchestration/ and this time not everything went good.

I stuck on docker container run -it --rm linkextractor:step1 http://example.com/ command, which works in shell of website, but on my cmd I get this output: /usr/bin/env: ‘python\r’: No such file or directory. I double checked and double did it, and I'm sure I did exactly as It was mentioned.

So I think some improvements are needed on training or maybe the linkextractor's Dockerfile. I don't know exactly what! After all, I'm just a beginner. Thanks!
