Creating a timer in python
提问by user2711485
import time
def timer():
now = time.localtime(time.time())
return now[5]
run = raw_input("Start? > ")
while run == "start":
minutes = 0
current_sec = timer()
#print current_sec
if current_sec == 59:
mins = minutes + 1
print ">>>>>>>>>>>>>>>>>>>>>", mins
I want to create a kind of stopwatch that when minutes reach 20 minutes, brings up a dialog box, The dialog box is not the problem. But my minutes variable does not increment in this code.
我想创建一种秒表，当分钟达到 20 分钟时，会弹出一个对话框，对话框不是问题。但是我的分钟变量在这段代码中没有增加。

You can really simplify this whole program by using time.sleep:
您可以使用time.sleep以下方法真正简化整个程序：
import time
run = raw_input("Start? > ")
mins = 0
# Only run if the user types in "start"
if run == "start":
# Loop until we reach 20 minutes running
while mins != 20:
print(">>>>>>>>>>>>>>>>>>>>> {}".format(mins))
# Sleep for a minute
time.sleep(60)
# Increment the minute total
mins += 1
# Bring up the dialog box here
回答by David
mins = minutes + 1
should be
应该
minutes = minutes + 1
Also,
还，
minutes = 0
needs to be outside of the while loop.
需要在while循环之外。

You're probably looking for a Timer object: http://docs.python.org/2/library/threading.html#timer-objects

Try having your while loop like this:
尝试让你的 while 循环像这样：
minutes = 0
while run == "start":
current_sec = timer()
#print current_sec
if current_sec == 59:
minutes = minutes + 1
print ">>>>>>>>>>>>>>>>>>>>>", mins

See Timer Objectsfrom threading.
请参阅线程中的计时器对象。
How about
怎么样
from threading import Timer
def timeout():
print("Game over")
# duration is in seconds
t = Timer(20 * 60, timeout)
t.start()
# wait for time completion
t.join()
Should you want pass arguments to the timeoutfunction, you can give them in the timer constructor:
如果要将参数传递给timeout函数，可以在计时器构造函数中提供它们：
def timeout(foo, bar=None):
print('The arguments were: foo: {}, bar: {}'.format(foo, bar))
t = Timer(20 * 60, timeout, args=['something'], kwargs={'bar': 'else'})
Or you can use functools.partialto create a bound function, or you can pass in an instance-bound method.
或者你可以使用functools.partial来创建绑定函数，或者你可以传入一个实例绑定方法。

Your code's perfect except that you must do the following replacement:
您的代码很完美，只是您必须进行以下替换：
minutes += 1 #instead of mins = minutes + 1
or
或者
minutes = minutes + 1 #instead of mins = minutes + 1
but here's another solution to this problem:
但这里是这个问题的另一种解决方案：
def wait(time_in_seconds):
time.sleep(time_in_seconds) #here it would be 1200 seconds (20 mins)

All you need is to sleep the specified time. time.sleep() takes seconds to sleep, so 20 * 60 is 20 minutes.
您所需要的只是在指定的时间睡觉。time.sleep() 需要几秒钟才能进入睡眠状态，因此 20 * 60 是 20 分钟。
import time
run = raw_input("Start? > ")
time.sleep(20 * 60)

# this is kind of timer, stop after the input minute run out.
import time
min=int(input('>>'))
while min>0:
print min
time.sleep(60) # every minute
min-=1 # take one minute
回答by tortue
import time
...
def stopwatch(mins):
# complete this whole code in some mins.
time.sleep(60*mins)
