#  1. 可以把代码进行分类.
#  2. 可以实现代码的重用.

# import random  #  一次性把模块所有内容导入
# from random import randint # 把模块加载。 导入randint
#
#
# random.randint()
# randint()

import random # 当你不确定你要用到什么
from random import randint  # 当你确定你要用到的东西

# # # 查找模块的路径
# # import sys, os, re
# #
# # import flask, django
# #
# # import yitian
# #
# #
# # # print(sys.path)
# #
# #
# # # 导入模块的时候会有三个动作
# # # 1. 先去sys.modules中查看当前导入的模块是否已经被导入.
# # #   如果该模块已经导入。 则不会重复导入
# # # 2. 开辟一个段内存空间。 在该空间中执行模块中的代码
# # # 3. 给该空间一个名称。 把该名称引入到当前模块中
# # import yitian
# # import yitian
# # import yitian
