The conversion between Python timestamp and datetime

In the development of unavoidable time-type conversion between the recent discovery front-end JS and back-end Django often use this conversion, where Jsdate.now () accurate to milliseconds, while Python Datetime.datetime.now () is accurate to microseconds.

1. String date time conversion to timestamp

# ' 2015-08-28 16:43:37.283 '-and 1440751417.283# or ' 2015-08-28 16:43:37 '-1440751417.0def string2timestamp ( strvalue):    try:                d = datetime.datetime.strptime (strvalue, "%y-%m-%d%h:%m:%s.%f")        t = d.timetuple ()        timeStamp = Int (time.mktime (t))        TimeStamp = float (str (timeStamp) + str ("%06d"% D.microsecond))/1000000        Print TimeStamp        return timeStamp    except ValueError as e:        print e        d = datetime.datetime.strptime (str2, "%y-% m-%d%h:%m:%s ")        t = d.timetuple ()        timeStamp = Int (time.mktime (t))        TimeStamp = float (str (timeStamp) + str ("%06d"% D.microsecond)) /1000000        print TimeStamp        return TimeStamp

2. Timestamp converted to string date time

# 1440751417.283 to ' 2015-08-28 16:43:37.283 ' def timestamp2string (timeStamp):    try:        d = Datetime.datetime.fromtimestamp (timeStamp)        str1 = D.strftime ("%y-%m-%d%h:%m:%s.%f")        # 2015-08-28 16:43:37.283000 '        return str1    except Exception as e:        print e        return '
