python timestamp和datetime之间的转换_python中时间戳，datetime 和时间字符串之间得转换...

# datetime时间转为字符串

def Changestr(datetime1):

str1 = datetime1.strftime('%Y-%m-%d %H:%M:%S')

return str1

# 字符串时间转为时间戳

def Changetime(str1):

Unixtime = time.mktime(time.strptime(str1, '%Y-%m-%d %H:%M:%S'))

return Unixtime

# datetime时间转为时间戳

def Changestamp(dt1):

Unixtime = time.mktime(time.strptime(dt1.strftime('%Y-%m-%d %H:%M:%S'), '%Y-%m-%d %H:%M:%S'))

return Unixtime

# 时间戳转为datetime时间

def Changedatetime(timestamp):

dt = datetime.datetime.fromtimestamp(timestamp)

return dt

# uinx时间戳转换为本地时间

def Localtime(datetime1):

Localtime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(datetime1))

return Localtime

# 字符串时间转换函数

def Normaltime(datetime1):

Normaltime = datetime.datetime.strptime(datetime1,'%Y-%m-%d %H:%M:%S')

return Normaltime
