NumPy(Numerical Python)是一个开源的 Python 库,几乎在每个科学和工程领域中都被使用。它是 Python 中处理数值数据的通用标准,在科学 Python 和 PyData 生态系统的核心地位不可撼动。NumPy 的用户包括从初学者程序员到经验丰富的从事最前沿的科学和工业研究与开发的研究人员。NumPy API 在 Pandas、SciPy、Matplotlib、...
这是一个被广泛采用的惯例,可以使你的代码对每个人在上面工作时更容易阅读。我们建议始终使用import numpy as np导入。 阅读示例代码 如果你还不习惯阅读包含大量代码的教程,你可能不知道如何解释如下的代码块: >>>a = np.arange(6)>>>a2 = a[np.newaxis, :]>>>a2.shape (1,6) 如果您不熟悉这种风格,...
