python编程实战:制作秒表程序
现如今生活节奏的加快,再加个人们对营养的需求也是在不断加大。我们平时所食用的食物只有在它烹饪到刚刚好的时候才会把它自身的营养充分的发挥出来,可是我们一般对于它的时间方面不是很好把握,所以对于这一点,秒表计时器就帮了我们很大的忙。秒针在生活中一般用作精确计时,作用很大。那你知道用我们万能的python怎么做秒表吗?下面我们来看看吧~
代码:
#! python3
# stopwatch.py - A simple stopwatch program.
import time
# Display the program's instructions.
print('Press ENTER to begin. Afterwards, press ENTER to "click" the stopwatch. \
Press Ctrl-C to quit.')
input() # press Enter to begin
print('Started.')
startTime = time.time() # get the first lap's start time
lastTime = startTime
lapNum = 1
# Start tracking the lap times.
try:
while True:
input()
lapTime = round(time.time() - lastTime, 2)
totalTime = round(time.time() - startTime, 2)
print('Lap #%s: %s (%s)' % (lapNum, totalTime, lapTime), end='')
lapNum += 1
lastTime = time.time() # reset the last lap time
except KeyboardInterrupt:
# Handle the Ctrl-C exception to keep its error message from displaying.
print('\nDone.')
以上就是python制作秒表程序的过程,看起来复杂,但其实很简单,快试试吧~
