在Python中查找两个时间字符串之间的差异

Question

我有两次字符串格式HHMM，我想在分钟内找出差异。在

我尝试了以下方法，但出现以下错误：

TypeError:不支持-：'的操作数类型日期时间.time'和'日期时间.time'

import datetime  

a = "0628"
b = "0728"

aSep = a[:2] + ':' + a[2:]
bSep = b[:2] + ':' + b[2:]

timeA = datetime.datetime.strptime(aSep, '%H:%M').time()
timeB = datetime.datetime.strptime(bSep, '%H:%M').time()

diff = timeB -timeA
print diff

Answer 1

import datetime  

a = "0628"
b = "0728"

timeA  = datetime.datetime.strptime(a, "%H%M")
timeB  = datetime.datetime.strptime(b, "%H%M")

print((timeB-timeA).total_seconds())
print(((timeB-timeA).total_seconds()/60.0))

输出：

^{pr2}$
