| + | === [0p] Task 1.5 - Debugging scripts === | ||
| + | |||
| + | If you ever need to debug your python program, the best approach is to open up a shell and run your program a bit tedious (copy pasting each line of the program). However, there's a better method: | ||
| + | |||
| + | <code python> | ||
| + | import IPython | ||
| + | |||
| + | IPython.embed(colors='neutral') | ||
| + | </code> | ||
| + | |||
| + | <note tip> | ||
| + | <code bash> | ||
| + | $ sudo apt install ipython3 | ||
| + | </code> | ||
| + | </note> | ||
| + | |||
| + | This will stop the execution of your script and open an ipython shell that has access to a copy of all your local & global data. Use this to inspect the state of your variables, their types, etc. Exit the shell (Ctrl + D) to continue the execution. | ||
