Heim >Backend-Entwicklung >Python-Tutorial >Python erhält die lokale Zeit-/Datumsformatierung
Erhalten Sie die aktuelle Uhrzeit:
Python-Code
import time print time.time() #获取当前时间 print time.strftime("%Y-%m-%d %X ") #获取当前时间(按照指定格式)
Verwenden Sie die Methode time.localtime(), die den Zeitstempel als Ortszeit formatiert:
Python-Code
import time print time.localtime(time.time())
Ausgabeergebnis: time.struct_time(tm_year=2015, tm_mon=11, tm_mday=513, tm_hour=15, tm_min=48, tm_sec=28, tm_wday=3, tm_yday=309, tm_isdst = 0)
Jetzt sieht es vielversprechender aus, es auf die von uns gewünschte Zeit zu formatieren.
time.strftime('%Y-%m-%d',time.localtime(time.time()))
Python-Code
import time print time.strftime('%Y-%m-%d',time.localtime(time.time()))
Endlich Zeit nutzen. Die strftime()-Methode formatiert die große Informationsfolge gerade in das, was wir wollen. Das aktuelle Ergebnis ist: 2015-11-05
ime.strftime hat viele Parameter, die es Ihnen ermöglichen, lockerer auszugeben, was Sie möchten wollen:
Das Folgende sind die Parameter von time.strftime:
strftime(format[, tuple]) -> Die angegebene struct_time (Standard ist die aktuelle Zeit), Ausgabe gemäß die angegebene Formatzeichenfolge
