函数func_out()里的变量 str1 = str1 + " World" func_inner() return str1 if __name__ == "__main__": print(func_out()) 结果： Hello World ★第6章、python3内置函数 内置函数是指不用import导入任何模块就能直接使用的函数 包名x 下的__init__.py里的 __all__=[这里列出的函 数及变量] 一个模块被另一程序第一次导入时，其主程序将运行，若不想让它运 行，可做个判断： if __name__=="__main__": #被导入模块的主程序写这里，只有它自己执行时才运行这里的代码 else: #来自另一程序的调用 import sys as xx #将导入的模块名 tar.gz模块安装包一样打包我们的源代码并执行setup.py去安装我们 的代码模块，可以使用distu�ls模块里的setup函数去打包 例如，我们写的代码有cof.py及lee.py两个模块，main.py只是用于测试 的主函数 现在需要把cof.py及lee.py打包成一个安装包 在我们的源程序目录下再创建一个setup.py文件，内容如下： from distutils.core import

nothing to commit (create/copy files and use "git add" to track) # echo 'print("hello world")' > main.py #随便创建一个文件 # git add . #提交当前工作目录的所有文件到暂存区（add为暂存操 作），命令最后有一个点. # new file: main.py #暂存区有了一个新的文件：main.py # git commit -m "msgxxx" #将暂存区提交到仓库区（commit为提交操作），- m后指定本次提交的说明信息 1 file changed, 1 inser�on(+) create mode 100644 main.py # git config --global init.defaultBranch main #设置默认分支名为main，默认 为master；设置完成后，再init其他仓库，则默认名称生效（只对新创建仓库生 效） # git branch -m main #将当前分支更名为main ★tag操作 tag是git版本库的一个标记命令，指向

Irrational – The Hidden Forces That Shape Our Decisions By Dan Ariely “If I were to distill one main lesson from the research described in this book, it is that we are pawns in a game whose forces we more to do with our desires – with how we want to view ourselves – than with reality. “A second main lesson lesson is that althrough irrationality is commonplace, it does not necessarily mean that we
