This is a begginer question. I am writing a text game and have some problems.
code:
def river():
print "You are traveling through deciduous forest."
print "There is nothing going on, except a few squirrels and a hedge."
print "Squirrels are fighting over nuts and a hedge is getting fat eating an apple."
print "Then you see a wide, deep river. The stream is very strong."
print "What are you going to do next?"
print "1. Try to swim the river."
print "2. Watch the squirrels and hedge."
print "3. Turn back."
while True:
choice = raw_input("> ")
if choice == "1" or choice == "swim":
print """You are doing well when in the middle of a river
something begins to bite you near legs. The bitting gets stronger
and you soon realize that piranhas are tearing chunks of your meat
off. Soon there is nothing left of you that the bones. The piranhas
seems satisfied, since they got a free meal."""
dead()
if choice == "2" or choice == "watch":
print "You keep watching animals and are becoming more and more thirsty and hungry."
if choice == "3" or choice == "turn back" or choice == "turn":
start_rewind()
start()
I do not like these print statements. If I use multiline print, like under choice 1, the indentation does not look nice. It is in the same row as def river(). Is this a normal or a bad style? If i indent the text under choice I so it is in the same row as choice 1,.. then it does not look good when i start the script in command promt. How could i solve that?
Thanks
I would write something like this:
print ("You are traveling through deciduous forest.\n"
"There is nothing going on, except a few squirrels and a hedge.\n"
"Squirrels are fighting over nuts and a hedge is getting fat eating an apple.\n"
"Then you see a wide, deep river. The stream is very strong.")
The parentheses above implicitly continue the string. See the Python docs. For example:
print ("foo "
"bar")
and print "foo bar"
will give the same output. Note the space after "foo".
Note that there is a space between the print statement and the first parenthesis. In python3, where print is a function, there should be no space there.
try this:
print("""
You are traveling through deciduous forest.
There is nothing going on, except a few squirrels and a hedge.
Squirrels are fighting over nuts and a hedge is getting fat eating an apple.
Then you see a wide, deep river. The stream is very strong.
What are you going to do next?
1. Try to swim the river.
2. Watch the squirrels and hedge.
3. Turn back.

answer = int(raw_input("How many hours a day do you play computer games? "))
if answer < 2:
print "That seems a fairly healthy balance. Well done!"
elif:
print "You’re probably good enough by now with all that practice."
print "PS5 are better than any game console"
Errors keep popping up that says "There's an error in your program: expected an indented block"
When you code in python you have to indent the code otherwise you'll get the errors like you got. Other programming languages use ; such as php or java in order to differentiate the lines to execute, but in python we have the indentations. Besides, you can't use elif statement without some condition and if you don't have it you have to use else instead.
answer = int(raw_input("How many hours a day do you play computer games? "))
if answer < 2:
print "That seems a fairly healthy balance. Well done!"
else: # instead of elif, which requires a condition
print "You’re probably good enough by now with all that practice."
print "PS5 are better than any game console"
Im new to python so I decided to help myself learn by creating a basic game using python 3! My problem occurs whenever I try to use "def". When I try to run this program it skips all user input entirely because of the def. The goal of using a function in this case would be to return the player to the where it presents the two doors. Maybe its an issue related to indentation? If anyone could give it a shot and see if you can spot the error your help would be greatly appreciated! :D
def sec1 ():
print ("You have two doors in front of you. Do you choose the door on the left or right?")
room1 = input('Type L or R and hit Enter.')
if room1 == "L":
print ("********")
print ("Good choice",name)
elif room1 == "R":
print ("********")
print ("Uh oh. Two guards are in this room. This seems dangerous.")
print ("Do you want to retreat or coninue?")
roomr = input('Type R or C and hit enter.')
if roomr == "R":
print ("Good choice!")
sec1()
You have an indentation problem. Indentation matters in Python. According to the PEP8 styling guideline it is recommended to use 4 spaces instead of tabs for indentation. Also you are missing the name variable.
Below is a quick fix:
def sec1 ():
print("You have two doors in front of you. Do you choose the door on the left or right?")
room1 = input('Type L or R and hit Enter.')
name = "Player Name"
if room1 == "L":
print("********")
print("Good choice", name)
elif room1 == "R":
print("********")
print("Uh oh. Two guards are in this room. This seems dangerous.")
print("Do you want to retreat or coninue?")
roomr = input('Type R or C and hit enter.')
if roomr == "R":
print("Good choice!")
sec1()
sec1()
Why we have sec1() at then end?
Functions are like machines. It does nothing by it's own. Somebody has to operate it. sec1() (notice the parenthesis) at the end is sending a signal to start executing the function sec1 defined at the top.
I think the best way to learn is to put break points and use the debugger to learn which way the program flows.
Run the program in a debug mode and click on the icons to step through, step over etc. It sounds complicated but it is very easy and saves you a lot of time once you know how to do this feature.
Mathematical Functions
Maybe it is a bit off topic to mention Mathematical Functions here but I think, it's completely worth it. Functions in programming languages are heavily inspired by Mathematical Functions, however, in most of the programming languages these days (except functional programming languages like Haskell, F# etc) the concepts of the original Mathematical Functions are quite deviated over the year.
In Mathematics, the output of a function purely depends upon it's input and does not modify the values outside the function, however, in most of the programming languages this is not always the case and sometimes it can be a source of run time errors.
Tips
As you are a beginner, I highly recommend to use a proper IDE (Integrated Development Environment) if you haven't already. PyCharm has a free community version. IDEs come with a PEP8 style checker, debugger, profiler etc and help you to learn Python much more easily.
def sec1 ():
print ("You have two doors in front of you. Do you choose the door on the left or right?")
room1 = input('Type L or R and hit Enter.')
the function body should be indented
In Python, indentation is very important. Here's an example of your code with proper indentation (And a couple of liberties take on my part):
def sec1 ():
print ("You have two doors in front of you. Do you choose the door on the left or right?")
name = input('Enter your name.')
room1 = input('Type L or R and hit Enter.')
if room1 == "L":
print ("********")
print ("Good choice",name)
elif room1 == "R":
print ("********")
print ("Uh oh. Two guards are in this room. This seems dangerous.")
print ("Do you want to retreat or coninue?")
roomr = input('Type R or C and hit enter.')
if roomr == "R":
print ("Good choice!")
elif roomr == "C":
print ("Run!")
sec1()
I am making a text adventure game and I am trying to allow the user to quit the game using q. I don't know what to input, here's my code.
print ("Welcome to Camel!")
print ("You have stolen a camel to make your way across the great Mobi deset.")
print ("The natives want their camel back and are chasing you down! Survive your desert trek and out run the natives.")
print ("Welcome to Camel!")
print ("You have stolen a camel to make your way across the great Mobi deset.")
print ("The natives want their camel back and are chasing you down! Survive your desert trek and out run the natives.")
done = False
while done == False:
print("Print the letter only.")
print("A. Drink from your canteen.")
print("B. Ahead moderate speed.")
print("C. Ahead full speed.")
print("D. Stop for the night.")
print("E. Status check.")
print("Q. Quit.")
first_question = input("What do you want to do? ")
if first_question.lower() == "q":
done = True
if done == True:
quit
The lines are all indented properly in the code (the website makes it weird when copy pasting). Any help is appreciated.
Your program is nearly fine as is, and in fact it runs just fine in python3. The problem is that in python2, input will actually evaluate your input. In order to support python2, use raw_input.
print ("Welcome to Camel!")
print ("You have stolen a camel to make your way across the great Mobi deset.")
print ("The natives want their camel back and are chasing you down! Survive your desert trek and out run the natives.")
done = False
while done == False:
print("Print the letter only.")
print("A. Drink from your canteen.")
print("B. Ahead moderate speed.")
print("C. Ahead full speed.")
print("D. Stop for the night.")
print("E. Status check.")
print("Q. Quit.")
first_question = input("What do you want to do? ")
if first_question.lower() == "q":
done = True
if done == True:
break
Now, when you input 'Q' or 'q' program will quit.
It's about tabulation. Is that what you asked?
I'd like to start out that I'm new to programming. I've never taken any classes on it. I just decided it sounded interesting and try it.
Anyway, I've been reading the "Learn Python the Hard Way" online and have gotten to exercise 36. This exercise involves making my own text-based game. Now, for the question. When is an appropriate time to use and modify global variables? I just started my adventure and want to add things that the player has to do before other events happen, such as pull a lever in a different room before the gate in the first room opens. And if the player wishes to return to the first room later on, the gate and lever still be triggered.
Here's the code so far. Mind you it's not fleshed out. Just wanted to know if it worked.
print "You are a lone adventurer with the bounty to clear out the crypt."
print "You come with nothing but your sword and a compass."
print "You enter the crypt."
print "To the north you have a gated portaculas and rooms to the west and east."
print "What do you do?"
gate = False
lever = False
def entrance():
global gate
while True:
choice = raw_input('> ')
if choice == 'west':
guard_shack()
elif choice == 'east':
lever_rm()
elif choice == 'north' and gate == False:
print "The gate is still closed and locked."
entrance()
elif choice == 'north' and gate == True:
fountain_rm()
else:
entrance(gate)
def lever_rm():
global lever
global gate
print "You enter the room."
print "What do you do"
while True:
choice = raw_input('> ')
if 'search' in choice:
print "You look around the room and notice a lever on the opposite wall."
elif "pull lever" in choice:
print "You pull the lever."
lever = True
gate = True
elif choice == 'west':
entrance()
else:
print '> '
def fountain_rm():
print "you're in the lever room!"
entrance()
Unfortunately, many tutorials (and professors) teach bad code in the name of simplicity (and they usually never bother to teach the right way later). In this case, the problem is exacerbated by the fact that you are directly executing top-level code instead of putting it in a main function and using if __name__ == '__main__': main() at the end.
You should try to avoid all global state that can be mutated. It's okay to declare constants, or even lists/sets/dicts that you're not allowed to change. But everything else should be either passed as a function parameter, or stored as an attribute on self of some class.
If nothing else, think about how you would write unit tests in the presence of mutable global variables (hint: it's impossible).
To transform code like you've given, indent everything and add a heading class CryptGame:, add self as the first argument to every function, and replace all variables declared global foo with self.foo.
I was trying to make a simple Python game for some struggling math students at my high school, however our computers are not allowed to run Python due to security issues. So I decided to give them the code and have them run it online, but every site I go to says that the code has an EOFerror and an indention error. I have ran the code a dozen times in Powershell and everything was fine. It is always focused on my raw_input() statements. Can someone please tell me what is going on and any solution would by greatly appreciated. This is just the Intro so there is no math, just something to set the story.
