How to Use pdb.post_mortem in Python
Automatically enter the Python debugger at the exact point where an uncaught exception occurred, allowing interactive inspection of the crash site.
import pdb
import sys
def divide(a, b):
return a / b
def main():
try:
result = divide(10, 0)
print(f"Result: {result}")
except Exception:
# Enter post-mortem debugging when an uncaught exception occurs
pdb.post_mortem(sys.exc_info()[2])
if __name__ == "__main__":

Insert a breakpoint() call into your code to drop into an interactive debugger session where you can inspect variables and step through execution.
def calculate_total(prices, discount=0):
"""Calculates total price with optional discount."""
subtotal = sum(prices)
breakpoint() # Interactive debugging session starts here
final_total = subtotal * (1 - discount)
return final_total
