EZ question about python V2

[ManosMax13]

Why is it that sometimes a thing works and then when I restart jupyter notebook it has an error or just doesnt output anything

str = """song"""

x = str.lower().count("random word")

print=(x)

This doesnt do anything not even an output or an error when it used to work like a day ago why is that?

[ManosMax13]

This used to work and now it doesnt whats wrong?

I just restarted the kernel and it worked why would it do that?

python 2 doesn't have brackets for print.

print x

you should use python 3 though.

Sorry i posted another question and vw2 was about the question so i can categorize them as im learning and write the number someone so i can revisit it should have wrote no2. Btw do you know why some things dont work until resetting the kernel?

I don't know what "resetting the kernel" means

[colonel_mortis]

In the code snippet in your post, you put

print=(x)

You then fixed that in your screenshot to

print(x)

but it was too late at that point - as soon as you ran the first snippet, the name print had been reassigned from the print function to the value of x (a number). You needed to restart the kernel for it to forget about the assignment to print and reset it back to the builtin.

 

If you ever do that again in future and want to recover without restarting your kernel, you can reassign it from the builtin using

import builtins
print = builtins.print

(python 3 only).

It looks like a Jupyter notebook, so a kernel in that context just means the state in the current python context, so what variables have been assigned etc.
