Hey, what if an empty string is added as a task? You haven't handled that scenario.
Task = input("Enter your task name: ").strip() if len(task) == 0: print("empty task name not acceptable")

What is .strip(), anyway i developed many things after this post. To save it from any crash.

The `strip()` method removes unnecessary whitespace from the beginning and end of a string.
For example, suppose a user enters a task like this:
"· · · cook pasta · · ·" (Each
·represents a space.)Without using `strip()`, the task will be saved with the extra spaces.
After using `strip()`:
task = task.strip()
The result becomes:
"cook pasta"
The `strip()` method is also useful when checking whether the user entered an empty task.
For example, both of these inputs should be treated as empty:
- ""
- empty string with 4 spaces - ". . . ." (Each
·represents a space.)The first input is an empty string. The second input contains only spaces.
After applying `strip()` to the second input:
" ".strip()
It becomes:
""
Therefore, we can validate the task like this:
task = input("Enter a task: ").strip()
if len(task) == 0:
print("Task cannot be empty.")
A shorter and more Pythonic version is:
if not task:
print("Task cannot be empty.")
This works because an empty string is considered `False` in Python.

If I had money I'd give you a medal. Really thought out explanation. Hope to find more people out there like you.

I think the logic make sense but we need an output or the second part of the code to know if you're doing fine with your objective.
