The question confused me years. I always forgot to search the final answer. But today I get it, and share what I find here.

How can I debug manually typed expression and statements in pdb?

When you are in the recursive debug mode first time, type s , you will kwon what to do the next.

Let, you have a bunch of code. You put pdb, say line 3.

In this case, when you run the program, line 1 and line 2 is executed automatically and you can see the result by putting the variable name and from line 4 is not executed.

If you wanna see after line 3 result you have to write code which results you want to see or you can go next line using n, and c for continuing that means exit from debugging mode.

Thanks @Shaon but I do understand how to debug with Python but there is one command debug (see help command) that I don't understand. Do you have an example of how to use the debug command
