创建 x 个随机出生日期和 x 个比相应出生日期晚至少 18 年的日期

Question

我创建了一个随机出生日期列表，现在我想使用它创建一个随机开始日期列表，这些日期在 1 年 1980 月 1 日之后，至少在出生日期后 18 年。

我能够获得生成的随机出生日期，但我不确定如何使用这些日期来生成 1980 年 1 月 1 日之后和出生后至少 18 年的开始日期。

birthdates = []
import time
def strTimeProp(start, end, format, prop):
    """Get a time at a proportion of a range of two formatted times.
    start and end should be strings specifying times formated in the
    given format (strftime-style), giving an interval [start, end].
    prop specifies how a proportion of the interval to be taken after
    start.  The returned time will be in the specified format.
    """
    stime = time.mktime(time.strptime(start, format))
    etime = time.mktime(time.strptime(end, format))
    ptime = stime + prop * (etime - stime)
    return time.strftime(format, time.localtime(ptime))
def randomDate(start, end, prop):
    birthdates.append(strTimeProp(start, end, '%B %d %Y', prop))
for n in range(1000):
    randomDate("January 1 1960", "June 1 2001", random.random())

这将以 ['1974 年 1 月 5 日'， ...] 的格式创建一个包含 1000 个出生日期的列表，我想创建的第二个列表类似于 ['1992 年 1 月 10 日'，...]

我认为这对你有用：

birthdates = []
import time
import random
def strTimeProp(start, end, format, prop):
    """Get a time at a proportion of a range of two formatted times.
    start and end should be strings specifying times formated in the
    given format (strftime-style), giving an interval [start, end].
    prop specifies how a proportion of the interval to be taken after
    start.  The returned time will be in the specified format.
    """
    if len(start) == 6: 
        start = '0' + start[0] + '0' + start[1:]
    elif len(start) == 7: 
        start = '0' + start
    try:
        stime = time.mktime(time.strptime(start, format))
    except:
        year = start[:-4]
        stime = time.mktime(time.strptime("February 28 " + year, format))
    etime = time.mktime(time.strptime(end, format))
    ptime = stime + prop * (etime - stime)
    return time.strftime(format, time.localtime(ptime))
def randomDate(start, end, prop, list):
    list.append(strTimeProp(start, end, '%B %d %Y', prop))
for n in range(1000):
    randomDate("January 1 1960", "June 1 2001", random.random(), birthdates)
later_dates = []
for date in birthdates:
    month_day = date[:-4]
    year = date[-4:]
    randomDate(month_day + str(int(year) + 18), "June 1 2019", random.random(), later_dates)

列表later_dates将包含所需日期的列表。
