Why does running my Python script start taking a screenshot?
Question: I'm writing a script in Python, but when I attempt to run it a cross cursor
appears and lets me take screenshots. But that's not part of my program, and
the rest of the script never executes at all!

The minimal code that produces this behavior is:

    
    
    import fiona
    import scipy
    


Answer: It's a known issue which regularly happens to some.

Without a `python` shebang line the script is treated as a shell script. And
line `import module` is treated as a command to run `import` application,
which is present on your system (part of ImageMagick, I guess) and makes a
screenshot saving it to the specified file.
