WebApr 11, 2024 · 使用NumPy datetime64和timedelta64dtypes，我们整合了其他Python库中的大量功能，scikits.timeseries并创建了大量用于处理时间序列数据的新功能。 在处理时间序列数据时，我们会经常寻求： 生成固定频率日期和时间跨度的序列 使时间序列符合或转换为特定频率 根据各种非标准时间增量计算“相对”日期（例如，在一年的最后一个工作日之前 … import decimal def drange (x, y, jump): while x < y: yield float (x) x += decimal.Decimal (jump) And then: >>> list (drange (0, 100, '0.1')) [-1] 99.9. [editor's not: if you only use positive jump and integer start and stop ( x and y) , this works fine. For a more general solution see here .] Share. See more The cumulative error can simply be reduced by using an index variable. Here's the example: This example works as expected. See more You can go even further with plain standard library and compose a range function for the most of numeric types: This generator is … See more No nested functions. Only a while and a counter variable: This function will work well too, except for the cases when you want the reversed … See more If you want to use these functions with negative steps, you should add a check for the step sign, e.g.: The best option here is to raise StopIteration, if you want to mimic the rangefunction itself.
