python时间格式化、运行时长计算

1.格式化:

import time

timeStr=time.strftime('%Y-%m-%d %H:%M:%S',time.localtime()) #格式化为:2018-07-17 19:03:36形式

或者

timeStr=time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())) #格式化为:2018-07-17 19:03:36形式

print(timeStr)

 

2.运行时长:

import time

start=time.time()

print('the program starts at: %s' % time.time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(start)))

#do some work here

end=time.time()

print('the program ends at: %s' % time.time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(end)))

collapse=end-start

print('it takes %s seconds to finish the program.' % collapse)
