<p>我们可以:</p>
<ol>
<li>在开始和结束之间生成日期时间范围</li>
<li>循环该范围并计算正常秒数(长度-normal=premium)</li>
</ol>
<p>代码如下:</p>
<pre><code>import datetime
def split_hours(start, end):
# Total seconds
length = int((end-start).total_seconds())
# Generator with datetime objects
s = (start + datetime.timedelta(seconds=i) for i in range(length))
# Calculate normal and premium
# normal when hour > 7 AM, smaller than 7 PM and weekday not sat,sun
normal = sum(7 <= i.hour < 19 and i.weekday() not in [5,6] for i in s)
premium = length - normal
d = dict(normal=normal,
premium=premium,
total=dict(h=length/3600,m=length/60,s=length))
return d
</code></pre>
<p>现在我们可以做一些测试:</p>
<pre><code>start = datetime.datetime.now()
end1 = start + datetime.timedelta(hours=12)
end2 = start + datetime.timedelta(days=1)
end3 = start + datetime.timedelta(days=24)
print(split_hours(start,end1))
print(split_hours(start,end2))
print(split_hours(start,end3))
</code></pre>
<p>退货:</p>
<pre><code># 12 hours
{'total': {'h': 12.0, 's': 43200, 'm': 720.0}, 'premium': 26131, 'normal': 17069}
# 1 days / 24 hours
{'total': {'h': 24.0, 's': 86400, 'm': 1440.0}, 'premium': 43200, 'normal': 43200}
# 7 days
{'total': {'h': 168.0, 's': 604800, 'm': 10080.0}, 'premium': 388800, 'normal': 216000}
