Stack traces can be useful for both debugging when errors are raised or certain conditions happen. Here is the Python code [#1]
import traceback def add5(x1, y1): z1 = x1+y1 trace1 = "\n".join(traceback.format_stack()) print("Trace:") print("{0:s}".format(trace1)) return z1 def add4(x1, y1): z1 = add5(x1,y1) return z1 def add3(x1, y1): z1 = add4(x1,y1) return z1 def add2(x1, y1): z1 = add3(x1,y1) return z1 def add1(x1, y1): z1 = add2(x1,y1) return z1 z1 = add1(2,3) print("z={0:d}".format(z1))
Here is the output of the Python code.
