I ran all previous codes but the error says x is not defined. It would be great if anyone helps. Thanks a lot!
Simply says variable x is not defined, maybe you wrote X instead of x, or maybe you are not running that cell.
Thanks for your answer! I checked all these possible problems but I could not catch anything wrong.
I recommend you keep looking, because somewhere you are using ‘x’ incorrectly.
I will take a look at it again. Thank you!
Perhaps one lead is to find where your
x was defined. If
x is only defined inside a function, but is called outside the function, that error can happen. Or if you use
x inside a function, but the function definition line does not have a
x among its function input arguments, we may end up with that error too. Lastly, check if
xwas defined before it is called.
Thanks a lot for your response! But unfortunately, I still could not detect the error. I have just basic information about coding and Python.
Please download your notebook .ipynb file and send it to me via a private message. I’ll see if I can find the issue.
For others who may find this thread:
Python relies on your code to have correct indentation. Be sure you use consistent indentation for all of the code that is inside a code structure.
