python numpy求开方

要在Python中使用NumPy库求开方，可以使用sqrt()函数。以下是一个示例代码：

import numpy as np

def square_root(x):
result = np.sqrt(x)
return result

# 调用函数求开方
x = 16
result = square_root(x)
print("开方结果为：", result)

在这个示例中，我们导入了NumPy库，并定义了一个名为square_root()的函数，它接受一个参数x，并使用np.sqrt()函数来计算x的开方。然后我们调用这个函数，传入一个值x=16，并打印出结果。输出结果为：开方结果为：4.0。<span class="em">1</span><span class="em">2</span>
