Code Explanation:
🔹 1. Importing suppress
from contextlib import suppress
✅ Explanation
suppress is imported from Python's built-in contextlib module.
It is used to ignore specific exceptions.
If the specified exception occurs, Python does not stop the program.
Think of suppress() as a protective shield.
Program
│
Exception Occurs
│
suppress()
│
Ignore Exception
│
Continue Program
Nothing executes yet.
🔹 2. Creating a List
nums = [10, 20]
✅ Explanation
A list named nums is created.
Current Memory
nums
↓
[10, 20]
Visual Representation
Index
0 1
↓
10 20
The list contains only 2 elements.
🔹 3. Starting the with Block
with suppress(IndexError):
✅ Explanation
The with statement creates a context manager.
Here,
suppress(IndexError)
means:
"If an IndexError happens inside this block, ignore it."
It does not ignore every error.
Only this error:
IndexError
is suppressed.
🔹 4. Executing the Print Statement
print(nums[5])
✅ Explanation
Python tries to access index 5.
Current list:
Index
0 1
↓
10 20
Python searches for:
nums[5]
But there is no element at index 5.
Valid indexes are:
0
1
So Python raises:
IndexError
Normally the program would stop here.
🔹 5. How suppress() Handles the Error
with suppress(IndexError):
✅ Explanation
Since the error is exactly an IndexError, suppress() catches it.
Flow:
Access nums[5]
↓
IndexError
↓
suppress()
↓
Ignore Error
↓
Continue Execution
No error message is shown.
The program simply moves to the next line.
🔹 6. Printing "Done"
print("Done")
✅ Explanation
Because the exception was suppressed, Python continues executing.
It prints:
Done
🎯 Final Output
Done
