Python Numpy 标准差和平均值

Question

Can anyone please guide how to create Numpy array with predeifined Standard deviation and mean. For example mean should be 75 and std should be 12

Answer 1

See https://docs.scipy.org/doc/numpy-1.15.0/reference/generated/numpy.random.normal.html

in short, you can use

numpy.random.normal([mean], [standard deviation], [array size])

so for your example:

numpy.random.normal(75, 12, [array size])
