In java/c# you can easily step through code to trace what might be going wrong, and IDE's make this process very user friendly.
Can you trace through python code in a similiar fashion?
Yes! There's a Python debugger called
pdb just for doing that!
You can launch a Python program through
pdb by using
pdb myscript.py or
python -m pdb myscript.py.
There are a few commands you can then issue, which are documented on the
Some useful ones to remember are:
b: set a breakpoint
c: continue debugging until you hit a breakpoint
s: step through the code
n: to go to next line of code
l: list source code for the current file (default: 11 lines including the line being executed)
u: navigate up a stack frame
d: navigate down a stack frame
p: to print the value of an expression in the current context
If you don't want to use a command line debugger, some IDEs like Pydev have a GUI debugger.
