Add comment character # in many lines at once Python

Question

I am wondering, if its possible comment many lines at once in Python Jupyter Notebook or/and Spyder.

What I mean is to change this:

x=2
y=3
z=4
x=3
y=4
z=5

Into this

#x=2
#y=3
#z=4
x=3
y=4
z=5

Is it possible? It would speed up my work many times :)

This depends on your text editor, not Python. It is possible with many text editors — Chris_Rands, Dec 13 '16 at 11:23
I meant Jupyter notebook or Spyder :) Do you know how to do it there? — Kuba, Dec 13 '16 at 11:28
I've duplicated this to an existing question on how to do this in Spyder. For Jupyter, see [How do I comment out multiple lines in Jupyter Ipython notebook?](//stackoverflow.com/q/29885371) — Martijn Pieters, Dec 13 '16 at 11:30

Not entirely sure that I understood correctly, but this available per editor.

For example, in each editor you'll have a shortcut for commenting out/in lines at once, so it depends on the editor.

In Jupyter for example, you can use Ctrl + / which works for me.

As if you're writing just in a simple notepad, I can however suggest the following three single-quotes at the start and at the end.

For example:

'''x=2
y=3
z=4
x=3'''
y=4
z=5

So the part from x=2 to the part of x=3 is currently commented out from the code and won't be executed.
