我正在寻找一种方法将“明天上午6点”或“下周一中午12点”翻译成相应的日期时间对象。
我考虑过制定一个复杂的规则集,但是否有其他方法?

parsedatetime - 一个Python模块,能够解析“人类可读”的日期/时间表达式。
#!/usr/bin/env python
from datetime import datetime
import parsedatetime as pdt # $ pip install parsedatetime
cal = pdt.Calendar()
now = datetime.now()
print("now: %s" % now)
for time_string in ["tomorrow at 6am", "next moday at noon",
"2 min ago", "3 weeks ago", "1 month ago"]:
print("%s:\t%s" % (time_string, cal.parseDT(time_string, now)[0]))
now: 2015-10-18 13:55:29.732131
tomorrow at 6am: 2015-10-19 06:00:00
next moday at noon: 2015-10-18 12:00:00
2 min ago: 2015-10-18 13:53:29
3 weeks ago: 2015-09-27 13:55:29
1 month ago: 2015-09-18 13:55:29
parsedatetime
模块后,仍然显示No module named 'parsedatetime'
。 - Cyzanfar#!/usr/bin/env python3
来解决了这个问题。 - NSSynapse看看你对这个例子的看法。它处理以下测试案例:

可以在Linux上接受一些可读日期,例如:date --date='下周一上午8:30'
