3.2 Lists and Dictionaries

By Last updated: 

cities = ["Pune", "Solapur", "Nashik", "Sambhaji Nagar", "Kolhapur", "Nagpur"]
print(cities[0])          # Pune
print(len(cities))        # 6

# dict: city -> fictional manager
managers = {
    "Pune": "Ravindra Bagale",
    "Nashik": "Shraddha Bagale",
    "Nagpur": "Ruhi Bagale",
}
print(managers["Pune"])
print(managers.get("Satara", "Unknown"))  # safe default

Steps in Jupyter

  1. Create the cities list above.
  2. Append "Pune" again with cities.append("Pune") — lists allow duplicates.
  3. Build managers and print Nashik’s manager.

What you should see. Indexing starts at 0. .get avoids KeyError.
