Consider this code snippet simulating battery swapping availability:

stations = {"StationA": 3, "StationB": 0, "StationC": 5}
available = [name for name, count in stations.items() if count > 0]
print(available)

What will be the output?

A["StationA", "StationC"]

B["StationA", "StationB", "StationC"]

C["StationB"]

D[]

Step-by-Step Solution

Solution:

Step 1: Understand the dictionary and list comprehension
The dictionary shows battery counts at stations. The list comprehension selects stations with count > 0.
Step 2: Evaluate each station's count
StationA has 3 (>0), StationB has 0 (not >0), StationC has 5 (>0). So only StationA and StationC are included.
Final Answer:
["StationA", "StationC"] -> Option A
Quick Check:
Filter count > 0 = ["StationA", "StationC"] [OK]

Quick Trick: Filter dictionary by positive values to find available stations [OK]
