g^i(i\in[1,p-1]) 遍历1 到p-1 ,其中 g 是原根。 如果要进一步学习其原理,建议系统学习相关数论知识。如果只是使用的话,可以记住常用的原根和质数,或者直接网上查表。后文就选取常用的质数 p = 998244353 和原根 g=3 ,为了计算方便,提前算出 g 模p 的逆gi = 332748118 Python代码如下,可以自行比较...
>>> import sys >>> sys.path.append('c:/python') 1. 2. 但更优雅的做法是配置pythonpath环境变量,方法和配置java 环境变量类似。 文档 模块信息的自然来源是文档,除了通过python书籍或标准python文档来查看某个函数的含义,也可以通过下面方式: >>> print range.__doc__ range([start,] stop[, step])...
最后的代码是: import matplotlib.pyplot as pltimport librosaimport librosa.displayimport globpath=glob.glob('E:/Python_On_All_Dataset/Four emotion_for plot/*.wav') fig, ax = plt.subplots(nrows=4, ncols=3, sharex=True) for i in range(4) : y, sr = librosa.load(path[i], sr=16000...

``f[-i]`` for all :math:`0 < i \leq n/2`` in Python gives the negative frequency terms. For an FFT of length :attr:`n` and with inputs spaced in length unit :attr:`d`, the frequencies are:: f = [0, 1, ..., (n - 1) // 2, -(n // 2), ..., -1] / ...
