python - how to get ln[]: in jupyter notebook?

Question

here how it looks like

I am new to the notebook and my code doesn't output. It just pretends all the code like as text. I suspect it is because I am not creating appropriate cell. every example on the internet has ln function near the cell and I just don't have that. how do I solve my problem? thx.

Answer 1

[] means the code in the cell is running and as you had asked for input from the user, the cell is waiting for receiving the input from the user. It will keep on showing the [] until you provide input and press the entre button. After pressing the entre button, the input will be stored in the name variable. And finally, that input will be printed as Hello NAME!. After the code runs successfully, the [*] will be changed to [1].
In your case, the cell is waiting to receive the input from the user. So, as soon as you provide the input, the cell will be executed successfully.
