Unable to execute python codes in Jupyter Notebook

[amitsharma23]

I recently started learning python for data science. I installed anaconda (Python 3.6). Post installation, when I wrote 'Jupyter Notebook' in Anaconda Prompt to open Jupyter, the notebook got opened. However, I was unable to execute any codes in the notebook. I installed anaconda after turning off my anti-virus software but the Jupyter wasn't running any codes. I have added the screenshot of the Anaconda Prompt after writing 'Jupyter Notebook'. Please look into it and assist further. I am new to programming.

How did you try to run the cells? Press shift-enter or use the run button in the toolbar.

I tried every possible way to run codes. Shift + Enter, using Run button, and Ctrl + Enter. Yet, I am unable to run my codes.

Did you have a cell with code in selected when you did that? All those options only work on the currently selected cell.

[amitsharma23]

Yes, the cell was selected when I performed those commands.

[takluyver]

No idea, then, sorry.

As I was unable to execute any codes in Jupyter, one of my friend suggested me to check for 'inspect' and I found that something is not right. It says that the Kernel is not active. Please tell me the next steps in simple language as I do not have any programming background.

I think that means it's not able to start the kernel, but I don't know why that is. Is there any more output that could be relevant in the command prompt where you launched Jupyter?

It is quite possible to get a lot of jupyter notebooks going. If you do that, at some point, you run out the resources needed to run.

Try using the File Open menu item, you'll see a list of files. Look for and click on "Running".
You can press the Shutdown button to turn off stuff you are not using. That can free up resources
and let your notebook run.

I have kind of the same problem, but before opening the python code book it says the app could not open. and in the details of the problem, it says appcrash.
