获取下个周三的日期

```python

def get_wednesday_date():
return date.today() + timedelta(((2 - date.today().weekday()) + 7) % 7)

```

import datetime

now=datetime.datetime.now()
dayslater=now+datetime.timedelta(7)
print(dayslater.strftime('%Y%m%d'))

php:

datetime('Y-m-d H:i:s', strtotime('next Wednesday'));

@Jakesoft php 原生没有 datetime 函数吧。 echo date('Y-m-d', strtotime('next Wednesday'));

def get_wednesday_date():
today = datetime.datetime.today().isoweekday()
time_delta = timedelta(date=3 - today + (3<today) * 7)
return today + time_delta

搞不懂~我的不是最简洁的吗？

```jodatime or javase8

LocalDate localDate = LocalDate.now();
System.out.println(localDate.with(DayOfWeek.WEDNESDAY).plusWeeks(1));

```

@tumbzzc 审题错误，零分

给另一个 Joda Time 的写法
DateTime nextWednesday = new DateTime().withDayOfWeek(3).plus(Weeks.ONE);

```
>>> import parsedatetime
>>> cal = parsedatetime.Calendar()
>>> cal.parse("next Wednesday")
(time.struct_time(tm_year=2016, tm_mon=12, tm_mday=7, tm_hour=9, tm_min=0, tm_sec=0, tm_wday=2, tm_yday=342, tm_isdst=-1), 1)
>>> cal.parse("this coming wednesday")
(time.struct_time(tm_year=2016, tm_mon=11, tm_mday=30, tm_hour=19, tm_min=59, tm_sec=28, tm_wday=2, tm_yday=335, tm_isdst=-1), 1)
```

（逃……

感觉 @Contextualist 的比较清真

* 安装
```shell
pip install isoweek
```

* 使用
```python
In [1]: from isoweek import Week

In [2]: (Week.thisweek() + 1).wednesday()
Out[2]: datetime.date(2016, 12, 7)
```

，　搞成下周的周三了

```python
In [1]: from datetime import datetime

In [2]: from isoweek import Week

In [3]: def coming_weekday(num):
...: this_week = Week.thisweek()
...: this_weekday = this_week.day(num)
...: return this_weekday if this_weekday > datetime.now().date() else (this_week + 1).day(num)
...:

In [4]: coming_weekday(2)
Out[4]: datetime.date(2016, 11, 30)

In [5]: # 0 is Monday
```

```python
In [13]: def coming_weekday(num):
this_week = Week.thisweek()
return (this_week + (not this_week.day(num) > datetime.now().date())).day(num)
....:
```
