converted to the specified format. So what's the reverse? The same needs to be converted to struct_time , this work is done by the time.strptime() function. strptime p should be in the meaning of parse, the prototype is: strptime(string, format) -> struct_timeThe time in the form of a string is parsed in the specified format and converted to struct_time . Then pass the time.mktime() final work to completion, the whole process is: In [12]: import time In [13]: st = time.strptime(‘2
