How do you catch multiple exceptions in Python? Python में multiple exceptions कैसे catch करें?

Answer

# Catching multiple exception types with one handler
try:
    value = int(input('Enter a number: '))
    result = 10 / value
except (ValueError, ZeroDivisionError) as e:
    print(f'Error occurred: {e}')

# Separate handlers for different exceptions - runs top to bottom, first match wins
try:
    data = {'a': 1}
    print(data['b'])
except KeyError:
    print('Key not found')
except ValueError:
    print('Invalid value')  # not reached, KeyError matched first
except Exception as e:
    print(f'Unexpected error: {e}')  # catch-all, should be LAST

# Order matters - specific exceptions before general ones
try:
    risky_operation()
except ZeroDivisionError:
    print('Specific handler')
except Exception:
    print('General handler')
# If order was reversed, Exception would catch everything first,
# making the ZeroDivisionError handler unreachable (dead code)

# एक handler में multiple exception types catch करना
try:
    value = int(input('Enter a number: '))
    result = 10 / value
except (ValueError, ZeroDivisionError) as e:
    print(f'Error: {e}')

# अलग-अलग exceptions के लिए अलग handlers
try:
    data = {'a': 1}
    print(data['b'])
except KeyError:
    print('Key नहीं मिली')
except ValueError:
    print('गलत value')
except Exception as e:
    print(f'अनपेक्षित error: {e}')  # catch-all, आखिर में होना चाहिए

# Order important है - specific exceptions पहले
try:
    risky_operation()
except ZeroDivisionError:
    print('Specific handler')
except Exception:
    print('General handler')
