首先说明一下:import导入的可以是包,也可以是模块。导入过程,导入包和模块后通过"."调用方法 第一种导入方法(直接导入) (1)import包/方法 (2)调用具体方法 1 2 importrandom print(random.randint(1,6)); #注意# randint是random模块下的一个具体方法(def) 第二种导入方法(跳跃式) (1)from 包/模块 impo...

The source code of the game makes use of the time and random module:Python reaction_game.py from time import perf_counter, sleep from random import random print("Press enter to play") input() print("Ok, get ready!") sleep(random() * 5 + 1) print("go!") start = perf_counter(...
PRNG options include the random module from Python’s standard library and its array-based NumPy counterpart, numpy.random. Python’s os, secrets, and uuid modules contain functions for generating cryptographically secure objects. You’ll touch on all of the above and wrap up with a high-level...
