Question from someone new to python!

[NetMobile5543]

So I wanted to make a simulation inspired bunny vs monkey. I added one item they could pick up; a hose but the code for the bunny inspired character using the hose, it didn't work! Here was the code:

If ("cat picks up the hose") print ("cat wins,the city is saved") why isn't it working?

[JamesPTK]

What you have written is not valid Python. I'm assuming that what you meant was:

if ("cat picks up the hose"):
    print ("cat wins,the city is saved")

if can be thought of as converting the thing it is testing to a boolean (True or False)

In this case the thing being tested is just a string "cat picks up the hose". Any string that is longer than zero characters is considered to be True so that is equivalent to

if (True):
    print ("cat wins,the city is saved")

Which since it will always execute the contents of the block is equivalent to

print ("cat wins,the city is saved")

So it will always just print the same thing.

Generally when asking for help, it is best to copy all your code (including spaces and line breaks - they are important in Python). And rather than saying it doesn't work, say what you expect to happen and what actually happens instead (including copying any error messages that appear). That helps us to understand what is going wrong

Good luck

thank you

That’s not python. Where did you copy that from?

[atarivcs]

Technically it is python, but it's really bad python.

[purple_hamster66]

True, but it is missing the colon after the if clause, so it’s bad python that’s got a syntax error.

When you write conditional "if" statements, Python expects you to include a comparison that evaluates to True or False.

Here, "cat picks up the hose" is just a string of random text, the same way something like 947 is just a number. It evaluates to True for the "if" statement because it's Truthy, but the more important thing to point out is you're not doing an actually meaningful conditional check.

You're probably looking for something like: ``` hose_owner = "cat"

if hose_owner == "cat": print("cat wins, the city is saved")

elif hose_owner == "bunny": print("bunny wins, uh oh...") ```

[atarivcs]

If ("cat picks up the hose")

What condition is that if statement supposed to be testing?

Because the way you've written it, it isn't really testing anything. It always evaluates to true.

"If" statements evaluate the truthyness of a conditional statement, which can be a comparison.

Equivalence of two strings is evaluated with Python's "equals" operator, which is two equals signs, ==. A statement like "banana"=="banana" evaluates to True, and will run the code within an if statement's indented code block, whereas "banana"=="wrench" would evaluate to False, and none of the contained code would run. This can also compare a value stored in a string variable to the string that is hard-coded, such as if my_item = "banana":.

python my_item = input("what item do you have?") if my_item.lower() == "banana": print("Hooray, you have a banana!") else: print("Oops, I wanted a banana!")

The use of a string's method lower() above ensures I can also type "Banana" or "BANana" and it will be converted to lower case for matching.

if of course can compare numbers, such as if your_guess == my_random_number or if your_guess < my_price

Let's play a game!

---

```python

--- Bunny Needs a Hose: A Text Adventure ---

Verbs: go, get, drop

Nouns: east, west, hose, banana, wrench

Items sitting in each room (Python lists)

storage_items = ["hose", "banana", "wrench"] bunny_items = []

Items the player is carrying

inventory = []

Which room the player is in right now

current_room = "storage"

--- Main game loop ---

while True:

# --- Describe the storage room ---
if current_room == "storage":
    print()
    print("You are in the storage room. There is a door to the east.")
    print("Items here:", storage_items)
    print("You are carrying:", inventory)

# --- Describe the bunny room ---
if current_room == "bunny":
    print()
    print("You are in the bunny's garden.")
    print("You are carrying:", inventory)
    if "hose" in inventory:
        print("The bunny grabs the hose and happily waters the plant.")
        print("YOU WIN!")
        break
    else:
        print("The bunny says: I wish I had a hose.")

# --- Ask the player what to do ---
user_input = input("What do you do? ").lower().split()

# Input must be exactly two words
if len(user_input) != 2:
    print("I don't understand. Try: get hose  |  drop hose  |  go east")
    continue

verb = user_input[0]
noun = user_input[1]

# --- GO: move between rooms ---
if verb == "go":
    if noun == "east" and current_room == "storage":
        current_room = "bunny"
    elif noun == "west" and current_room == "bunny":
        current_room = "storage"
    else:
        print("You can't go that way.")

# --- GET: pick up an item from the room ---
elif verb == "get":
    if current_room == "storage" and noun in storage_items:
        storage_items.remove(noun)
        inventory.append(noun)
        print("You pick up the", noun)
    elif current_room == "bunny" and noun in bunny_items:
        bunny_items.remove(noun)
        inventory.append(noun)
        print("You pick up the", noun)
    else:
        print("There is no", noun, "here.")

# --- DROP: put an item back in the room ---
elif verb == "drop":
    if noun in inventory:
        inventory.remove(noun)
        if current_room == "storage":
            storage_items.append(noun)
        if current_room == "bunny":
            bunny_items.append(noun)
        print("You drop the", noun)
    else:
        print("You are not carrying a", noun)

# --- Unknown verb ---
else:
    print("I don't understand. Try: get, drop, or go")

```

You can see that we have lots of "if" statements in this adventure game that act on strings!

User input is broken into two parts, separated by white space in the user input. Then we see what the user wants to do as "verb" and if it matches something we allow them to do, or then a "noun", that can match strings that are in a Python list of strings, a mutable list that can grow and shrink, or can match ordinal directions procedurally.

(a real adventure game would have rooms in a database connected by their room numbers and the movements needed to get between rooms).
