Breakpoint-induced interactive debugging of Python with IPython

Question

The Tracer() still exists in ipython in a different module. You can do the following:

from IPython.core.debugger import Tracer

def my_function():
    x = 5
    Tracer()()
    print 5

Note the additional call parentheses around Tracer

edit: For IPython 6 onwards Tracer is deprecated so you should use set_trace() instead:

from IPython.core.debugger import set_trace

def my_function():
    x = 5
    set_trace()
    print 5
