python pdb 如何继续下 x 个循环

Question

I need to debug a for loop in python but it needs to continue for many iterations before the bug shows up.

Now I could just press 'c' in pdb every time to advance to the next iteration but I was wondering, is there a way to say 'c 20' and make it continue the next 20 loops before stopping?

thanks

First, see the pdb documentation. Failing that, insert a counter:

count = 0
while cond:    # your current loop
    ...
    count += 1
    if count > 20:
        count = 25
        # Put a breakpoint here.
        # When you reach this point, insert any other debugging you want.

    # Code you want to trace
    ...
