To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. How to compare a string with an Enum in Python | bobbyhadz class ...
虽然NumPy 为一般数值数据处理提供了计算基础,但许多读者将希望使用 pandas 作为大多数统计或分析的基础,尤其是在表格数据上。此外,pandas 还提供了一些更具领域特定功能,如时间序列操作,这在 NumPy 中不存在。 注意 Python 中的面向数组计算可以追溯到 1995 年,当时 Jim Hugunin 创建了 Numeric 库。在接下来的 10...
