Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
command=lambda arg=arg1: my_func(arg)
Why this is correct
Using default arguments in a lambda is a robust way to capture values.
- ✓
command=lambda: my_func(arg1)
Why this is correct
Lambda is the most common way to wrap functions with arguments.
- ✓
command=functools.partial(my_func, arg1)
Why this is correct
partial creates a new callable with the arguments pre-applied.
- ✗
command=my_func(arg1=value)
Why it's wrong here
This executes the function immediately.
- ✗
command=my_func(arg1)
Why it's wrong here
This executes the function immediately instead of setting it as the command.
