用户友好的时间格式在Python中？ [英] User-friendly time format in Python?

问题描述

Python：我需要在1天前，2小时前格式显示文件修改时间。

Python: I need to show file modification times in the "1 day ago", "two hours ago", format.

有没有可以做的事情？它应该是英文的。

Is there something ready to do that? It should be in English.

代码最初发布在博客文章Python Pretty Date function（ http://evaisse.com/post/93417709/python-pretty-date-function ）

def pretty_date(time=False):
    """
    Get a datetime object or a int() Epoch timestamp and return a
    pretty string like 'an hour ago', 'Yesterday', '3 months ago',
    'just now', etc
    """
    from datetime import datetime
    now = datetime.now()
    if type(time) is int:
        diff = now - datetime.fromtimestamp(time)
    elif isinstance(time,datetime):
        diff = now - time
    elif not time:
        diff = now - now
    second_diff = diff.seconds
    day_diff = diff.days

    if day_diff < 0:
        return ''

    if day_diff == 0:
        if second_diff < 10:
            return "just now"
        if second_diff < 60:
            return str(second_diff) + " seconds ago"
        if second_diff < 120:
            return "a minute ago"
        if second_diff < 3600:
            return str(second_diff / 60) + " minutes ago"
        if second_diff < 7200:
            return "an hour ago"
        if second_diff < 86400:
            return str(second_diff / 3600) + " hours ago"
    if day_diff == 1:
        return "Yesterday"
    if day_diff < 7:
        return str(day_diff) + " days ago"
    if day_diff < 31:
        return str(day_diff / 7) + " weeks ago"
    if day_diff < 365:
