It will great help if you can explain with code example or any useful resource.
you can use the in-built pdb
library.
import pdb
a = 10
pdb.set_trace()
print(a)
So what it would basically do is, stop the program after line 2 is executed. and from there you would have command line access to the code with is execute above the set_trace()
is added.
You can read more about it here.
