why my python cannot read files on my desktop : I'm new here and in python. There are 2 questions I'd like to ask:
1) I'm reading a .dat file on my desktop into my spider, but it shows  No such file or directory: 'C:\\Desktop\\movies.dat', but if I put the file into the default folder, 'C:\\Users\\User\\.spyder-py3\\movies.dat', it can read the file successfully. I thought that python3 can file the path in the quotes no matter if it is a default folder or not.
2) I've been reading some python books and in every beginning of each book, there is a chaper introducing Ipython and Jupyter orsomething like that, I don't quite understand what's the difference between, like, Anaconda, Spider, Jupyter notebook and Ipython. I'm currently using Spider and wondering what's the difference.

Great thanks if anythong can help!
