遍历年份列表

Question

我想循环遍历年份列表并计算每年按日期变化的国家法定假日。我遇到过一些可以用于此目的的库，但我未能在for循环中实现它们。

from datetime import date
from dateutil.easter import easter
from dateutil.relativedelta import relativedelta as rd
#range of years I want to compute this date for
year = list(range(2008,2019))
for i in year:
e = easter(year)
maundy_thursday = e - rd(days=3)

错误:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-150-1691b0469173> in <module>
2 
3 for i in year:
----> 4     e = easter(year)
5     maundy_thursday = e - rd(days=3)
6     good_friday = e - rd(days=2)
C:ProgramDataAnaconda3libsite-packagesdateutileaster.py in easter(year, method)
64 
65     y = year
---> 66     g = y % 19
67     e = 0
68     if method < 3:
TypeError: unsupported operand type(s) for %: 'list' and 'int'

Answer 1

看起来你在变量之间混淆了，最终是由误导性的名称引起的。

你有:

year = list(range(2008,2019))
for i in year:
e = easter(year)

注意，您将year变量传递给easter()函数，但这实际上是年份列表。

你的意思是:

years = list(range(2008,2019))
for year in years:
e = easter(year)

作为旁注，这里不需要list();你可以写:years = range(2008, 2019)
