For the inverse error function, scipy.special has erfinv:
对于逆误差函数，scipy。特殊erfinv:
http://docs.scipy.org/doc/scipy/reference/generated/scipy.special.erfinv.html#scipy.special.erfinv
http://docs.scipy.org/doc/scipy/reference/generated/scipy.special.erfinv.html scipy.special.erfinv
In [4]: from scipy.special import erfinv
In [5]: erfinv(1)
Out[5]: inf
In [6]: erfinv(0.4)
Out[6]: 0.37080715859355784

I suggest to use scipy, a library that uses numpy.
我建议使用scipy，一个使用numpy的库。
the module you need to import to use is erfinv:
您需要导入使用的模块是erfinv:
from scipy.special import erfinv
Scipy is a key player for numerical software in Python. But it might be a little challenging getting started with it.
Scipy是Python中数值软件的关键角色。但是要开始使用它可能有点困难。
