(x:y) operator in Julia
I am trying to understand this code:
r = (1:10) - (4/1)
println(r)
Output:
-3.0:1.0:6.0
I understood why I got -3 and 6. But why I got that value in the middle (1.0)? How does Julia calculate it? Or how I can google it?

With Python I can reuse another Jupyter notebook by importing it directly to a new one as a module (here in Anaconda) or using nbpackage.
Can this be done with Julia Jupyter notebooks? How to import functions from one notebook into another?
