我的陈述不起作用，我不知道为什么

Question

我将代码编辑到现在可以工作的地步：

def Reset():
data = []
data.append({
'year': now.year,
'months': []
})
for year in range(len(data)):
for month in range(12):
data[year]['months'].append({
'month': (month + 1),
'days': []
})
if (month+1 == 2):
daysAmount = 28
if (is_leap_year(now.year)):
daysAmount = 29
elif ((month+1) == 12):
daysAmount = 31
elif ((month+1)%2 == 0):
daysAmount = 30
else:
daysAmount = 31
for day in range(daysAmount):
data[year]['months'][month]['days'].append({
'day': (day + 1),
})
with open('data.json', 'w') as outfile:
json.dump(data, outfile)

重置((这是我让它工作后的输出：

经过核对的答案解决了我的问题。

Answer 1

此代码中有多个错误。

1. 闰年检查不正确。这是一个检查闰年的功能：

def is_leap_year(year: int) -> bool:
"""Determine whether a year is a leap year."""

return year % 4 == 0 and (year % 100 != 0 or year % 400 == 0)
is_leap_year(2020)  # True
is_leap_year(2022)  # False

2. 这应该是elif：

if ((month+1) == 12):

3. 偶数/奇数检查不正确。可以使用%(模数运算符(

if (month + 1) % 2 == 0:  # even
if (month + 1) % 2 != 0:  # odd

Answer 2

您检测月份的方法是错误的。您希望4/2是int类型，但事实并非如此。

type((3+1)/2)
<class 'float'>

无论如何，按类型检测偶数/奇数是非常错误的。

您应该使用模运算符%

if ((month+1) == 12):
daysAmount = 31
elif ((month+1)%2) == 0):
daysAmount = 30
else:
daysAmount = 31
