Start Delivery

Check Arrival

Drop Package

Return to Base

End Delivery

The drone starts delivery, checks the package, flies to destination, drops the package, and returns to base.

Execution Sample

Drone Programming

package_ready = True
location = "Home"
if package_ready:
    location = "Destination"
    print("Package delivered")
location = "Base"

This code simulates a drone delivering a package by changing its location and printing delivery status.

Execution Table

Step	package_ready	location before	Condition (package_ready?)	Action	location after	Output
1	True	Home	True	Fly to Destination	Destination
2	True	Destination	N/A	Print delivery message	Destination	Package delivered
3	True	Destination	N/A	Return to Base	Base
4	True	Base	N/A	End Delivery	Base

💡 Delivery complete, drone returned to base.

Variable Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	Final
package_ready	True	True	True	True	True
location	Home	Destination	Destination	Base	Base

Key Moments - 2 Insights

Why does the location change to 'Destination' only if package_ready is True?

Because the condition in the execution_table step 1 checks package_ready before flying. If False, the drone wouldn't fly to destination.

Why is there no output until the drone reaches the destination?

The print statement happens only after the drone flies to the destination (step 2), so output appears then.

Visual Quiz - 3 Questions

Look at the execution_table, what is the location after step 1?

A Base

B Home

C Destination

D Unknown

💡 Hint

Check the 'location after' column in row for step 1.

At which step does the drone print 'Package delivered'?

A Step 1

B Step 2

C Step 3

D Step 4

💡 Hint

Look at the 'Output' column in the execution_table.

If package_ready was False, what would happen to the location after step 1?

A Stay at Home

B Change to Destination

C Change to Base

D Undefined

💡 Hint

Refer to the condition check in step 1 and how location changes only if package_ready is True.

Concept Snapshot

Delivery drone concept:
- Check if package is ready
- Fly to destination if ready
- Print delivery confirmation
- Return to base
- End delivery

Full Transcript

This visual trace shows a delivery drone starting with a package ready at home. It checks if the package is ready, then flies to the destination. Upon arrival, it prints 'Package delivered'. Then it returns to base and ends delivery. Variables tracked are package_ready and location. The location changes from Home to Destination, then to Base. Output appears only after arrival. This helps understand step-by-step drone delivery logic.
