Errors & debugging
Handle failures gracefully, raise helpful errors, and debug with confidence.
How to Handle ValueError and Multiple Exceptions in Python
This code demonstrates try/except blocks for beginners, handling ZeroDivisionError, TypeError, and ValueError with two practical functions: dividing numbers and parsing strings to floats.
def divide_numbers(a, b):
"""Divide two numbers with error handling for beginners."""
try:
result = a / b
print(f"{a} / {b} = {result}")
return result
except ZeroDivisionError:
print(f"Error: Cannot divide {a} by zero!")
except TypeError:
print(f"Error: Both argu…
How to Use try except ValueError in Python to Parse Numbers
Convert strings to integers safely with try/except ValueError and TypeError, returning a value-or-error tuple.
def parse_number(text):
"""Safely convert a string to an integer, handling errors gracefully."""
try:
value = int(text)
return value, None
except ValueError as error:
return None, f"Conversion failed: {error}"
except TypeError as error:
return None, f"Wrong type provided…
Split try except ValueError handler for beginners in Python
Demonstrates how to handle ValueError and ZeroDivisionError separately using try/except blocks, with beginner-friendly examples for parsing and division.
def parse_number(text):
try:
number = int(text)
return f"Parsed successfully: {number}"
except ValueError as error:
return f"Conversion failed: {error}"
def divide_numbers(dividend, divisor):
try:
result = dividend / divisor
return f"Division result: {result}"
