import numpy用numpy的属性时,需要加上numpy.函数; from numpy import*用numpy属性时,不需要加上numpy.; 这里建议使用第一种方法,即加上numpy.。举例说明:numpy库中有random函数,标准库中也有random函数。
print(randint(1,10))# 这里就不需要random.前缀了 导入random模块下的randint, random函数: from random import randint, random 下面看下python import 和from import 区别 上网查了一下,貌似是一个简单问题,网上都是这么说的,我之前也是这么理解的: 假设有一个包名字叫 numpy, 里面有一个函数 zeros 1、 fro...

@juliantaylor raised this in a pandas issue. The example from the ticket: import numpy as np import random random.sample(np.array([1,2,3]),1) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/user1/py33/l...

所以调用时要用完整的函数名定向的指向。numpy.random()如果 from numpy import * 就会成为 main.py ...
