return 10 / 0
print(divideByZero()) # Raises a ZeroDivisionError
“`
Debugging Instruments
Debugging instruments are software program purposes that help builders in figuring out and resolving errors within the code. These instruments will be broadly labeled into two classes: print statements and debugging instruments. Print statements are used to print the values of variables or expressions throughout execution, whereas debugging instruments present extra superior options, akin to breakpoints, step-through execution, and reminiscence inspection.
Print Statements
Print statements are a easy and efficient approach to examine the circulation of the code and variables throughout execution. By inserting print statements at strategic places, builders can monitor the values of variables, operate calls, and loop iterations.
“`python
def findMax(numbers):
print(“Discovering most worth…”)
max_val = numbers[0]
for num in numbers:
print(f”Evaluating num and max_val”)
if num > max_val:
max_val = num
print(f”Most worth: max_val”)
return max_val
“`
Debuggers
Debuggers are software program purposes that present a variety of options to help builders in figuring out and resolving errors within the code. These options embody:

“`python
def findMax(numbers):
max_val = numbers[0]
for num in numbers:
if num > max_val:
max_val = num
return max_val
# Utilizing a debugger to step by way of execution
# Breakpoint hit at line 3
# Variable max_val = 10
# Variable num = 20
# …
