Almost like an RPG game, I want to make text appear as if someone is typing them. I have an idea of how to do it with the print() function in python, something involving the sleep() and maybe with sys.stdout.flush?
How would I do it text coming before an input function?
For example, I want What is your name? to be typed out, and then the user would input his name.
You can use this:
text = 'What is your name? '
for x in text:
sys.stdout.write(x)
sys.stdout.flush()
time.sleep(0.00001)
name = input()
you can randomize the sleep time per loop as well to mimic typing even better like this:
import time,sys,random
text = 'What is your name? '
for x in text:
sys.stdout.write(x)
sys.stdout.flush()
time.sleep(random.uniform(.000001, .000019))
name = input()
as Tomerikoo pointed out, some systems have faster/slow delays so you may need to use uniform(.01, .5) on another system. I use OS/X.
On windows this probably works better. Thanks Tomerikoo:
import time,sys,random
text = 'What is your name? '
for x in text:
print(x, end="", flush=True)
time.sleep(random.uniform(.000001, .000019))
# or smaller sleep time, really depends on your system:
# time.sleep(random.uniform(.01, .5))
name = input()
You can use the following code:
import time,sys
def getinput(question):
text = input(question)
for x in text:
sys.stdout.write(x)
sys.stdout.flush()
time.sleep(0.00001) #Sets the speed of typing, depending on your system
Now everytime you call getinput("Sample Question"), you would get the user's input based on the question you passed to the function.

My code is working well as expected but i would like to improve it. When a loop enter in a big time sleep like 100s how can i force it to change imediatly. if i miss input and put 400s and not 4s i would have to restart the program it's anoying. Here you can see the code
I tried many things like making other variable etc but i'm new and quiet lost.

Please see the other comments directing you on how to properly ask questions/how to use stack overflow.
Question issues aside, if I am understanding your question correctly, you are asking; "How can I adjust the delay of my checks, in case there is an emergent need?"
The problem with your current implementation, is that you are using time.sleep(), which is functionally suspending any processing until the time frame expires. This won't work, as you have discovered, since no changes can be made mid-sleep.
What you are looking to do, is to create a task scheduler. You would want to assign a date or time to a specific task, and have a task handler that would do processing of each task, depending on the particular time.
Subsequently, if something needs to be urgently processed, you would update the scheduled time of the task, to be processed as needed.

If you made a function like this:
def show():
print(something)
How would you make it so that, on any input, if the user typed a specific thing, this would be called? I want multiple functions like this to be able to be called whenever the user wants. Would I just have to have it as an option every time I ask for an input?
EDIT: sorry, this wasn't very clear. Say I have a variable in a game, like money. When I ask for an input as the game goes along, the inputs being about unrelated things, I want the user to be able to type eg. gold and the show() function will activate. Then the input will go on as usual. Would I be able to do this without just have it as an option for each input, eg.
variable = input("type something")
if variable == "gold":
do stuff
elif variable == other things
do other things
Do you mean something like this:
def thing1(): # Random command
print('stuff')
def thing2(): # Random command
print('More stuff')
def check(command):
'''Checks if the users command is valid else it does a default command'''
if command == 'thing1':
thing1()
elif command == 'thing2':
thing2()
else:
default_thing()
while True: # Loop going on forever
userinput = input('') # Lets the user input their command
check(userinput)
you could put all your functions in a dictionary: {"<some user input>":func_to_call} and see if it matches any
something like:
def gold():
print("gold")
input_options = {"gold":gold}
variable = input("type something:")
if variable in input_options:
input_options[variable]()

Is this possible? I'm doing an bukkit plugin now (in Python, yes :D), and I'm forced to do this within one function, so I can't separate it and call it later... For example, if I have loop that loops through players on server and adds everyone except one player, I want it to finish, and then teleport i.e. "Player1" to random player. At the moment, it teleports "Player1" to random player every time because of for loop... I'll give you just little of code, since It looks messy in preview due to many things that are not involved in problem and could be confusable to you... Here it is:
listica = []
for p1 in org.bukkit.Bukkit.getWorld(nextvalue).getPlayers():
if p1.getName() not in listica:
try:
listica.remove(event.getPlayer().getName())
randomtarget = choice(listica)
randomtargetreal = org.bukkit.Bukkit.getPlayer(randomtarget)
event.getPlayer().teleport(randomtargetreal)
event.getPlayer().sendMessage("%sYou teleported to: %s%s"% (bukkit.ChatColor.GREEN, bukkit.ChatColor.DARK_GREEN, randomtarget))
except ValueError:
randomtarget = choice(listica)
randomtargetreal = org.bukkit.Bukkit.getPlayer(randomtarget)
if event.getPlayer().getLocation() != randomtargetreal.getLocation():
event.getPlayer().teleport(randomtargetreal)
event.getPlayer().sendMessage("%sYou teleported to: %s%s"%(bukkit.ChatColor.GREEN, bukkit.ChatColor.DARK_GREEN, randomtarget))
What I want is:
run for loop:
when there is no more players to add a.k.a it finishes
do try loop
P.S. I can't do it in separate function.
Thanks in advance! :)
Do you mean:
def func(args):
for item in loop:
do something
try: # note indentation
something else

So, I've been using a simple paradigm for my command line application. One base class called "Command" is inherited multiple times so I can use the child classes to do my dirty work in a while loop. This while loop asked for a command and ran that input through a dictionary to point to the correct class and call Command().run() (The classes needed to be initialized for several unimportant reasons). It looks something like this:
class Command(object):
#Some of these parent variables where used as constants and
#redefined in the global scope
dir = ""
password = ""
target = ""
status_msg = "only for child classes"
def __init__(self):
self.names = [self.__class__.__name__.lower()]
def run(self):
raise NotImplementedError("There has to be code for the program to run!")
class End(Command):
status_msg = "Closing program and resources ..."
def __init__(self):
Command.__init__(self)
names = [
"exit", "close", "quit"
]
self.names.extend(names)
def run(self):
#Do checks and close resources?
sys.exit()
while True:
command = input("What will you be doing with said folder? ")
try:
cmd = commands[strip(command.lower())]() # Strip is defined elsewhere in the code
print("\n", cmd.status_msg, "\n")
cmd.run()
except Exception as __e:
print("Error: \n " + str(__e))
print("Perhaps you misspelled something? Please try again \n")
and other classes would overwrite the run commands and the class variables.
I've been wondering whether or not this is a Pythonic use of classes, and whether or not is efficient. In the end this amounts to two questions.
Is this a pythonic use of classes?
Is this the most efficient way to code something like this?
Any help is welcome; I'm not a coding pro, but I always like to learn something new about one of my favorite coding languages! (I am willing to edit this post if you guys think the question is worded incorrectly, because I'm not completely confident it will make sense to everybody.)

Does anyone recall PGP prompting a user to "generate some entropy" by striking random keys?
PGP would measure the entropy as it was being collected, indicating to the user with a cool little progress bar, and internally would time the key strokes, do some processing and use this as a seed for something or other.
I want to make a quick routine (console app) that does a similar "entropy collection" step in python, but I'm at a loss regarding a number of issues :
Best method of timing
Best method of collecting individual keystrokes
Best method to display cool progress bar back to user
Ideas about processing step, or actual details of the PGP step.
Best in the above means :
Tightest cleanest code
Most accurate (as in timing to picosecond or something)
Most pythonic/functional and using the standard library
So yeah :
def gen_user_random():
from Fourganizical import pack8
import time,sys
print 'Hey there user, start a-bashing that keyboard to make some randomness.'
keystimes = []
lasttime = None
while len(keystimes) < 20:
key = getch()
timenow = (time.time() + time.clock())
if lasttime:
timesince = timenow-lasttime
keystimes.append(int(timesince*100000000000000000))
lasttime = timenow
print 'Check out this *nasty* random number you made!'
rnum = int(''.join([str(x) for x in keystimes]))
print rnum
print 'And OMG here is that *nasty* set of bytes it made!'
rbytes = pack8(rnum)
print
sys.stdout.write(''.join(rbytes))
print
print
return keystimes
This creates some really nasty randomness.
pack8 just takes an integer of any length and outputs it in radix 256 as a sequence of bytes.
