Welcome back, Pythoneers!
In our last newsletter, we explored the basics of if/else
statements. Now, we're taking our decision-making skills to the next level with nested conditionals and match-case statements!
Nested Conditionals
Sometimes, you need to make decisions within decisions. This is where nested conditionals come in handy. You can place an if/else
statement inside another one to create more complex logic.
temperature = 25
is_raining = True
if temperature > 20:
if is_raining:
print("It's warm and rainy. Take an umbrella!")
else:
print("It's a beautiful day!")
else:
print("It's a bit chilly.")
Example 2: Restaurant Recommender
if cuisine.lower() == "italian":
if budget > 20:
print("Try Trattoria Romana - they have delicious pasta dishes!")
else:
print("Check out Pizza Palace - great pizza for a good price!")
elif cuisine.lower() == "mexican":
print("Try Parrillada- A mixed grill platter featuring various meats!")
else:
print("Sorry, we don't have recommendations for that cuisine yet.")
Match-Case Statements (Python 3.10+)
If you're using Python 3.10 or later, you can use the new match-case
statement for a more structured way to handle multiple conditions.
day = "Tuesday"
match day:
case "Monday":
print("Ugh, start of the week!")
case "Friday":
print("TGIF!")
case "Saturday" | "Sunday": # Multiple patterns
print("Weekend vibes!")
case _: # Default case
print("Just another day.")
Challenge Time: The Expert Decision Maker
Your Mission: Enhance your decision-making program from last time. Add nested conditionals or use match-case statements to create even more complex choices and outcomes. For example, you could build a game with different levels of difficulty or a weather app that provides specific recommendations based on temperature and conditions.
Python Pro Tip:
While nested conditionals can be powerful, be careful not to make them too complex. If your code becomes too difficult to read, try breaking it down into smaller functions.
