在Jupyter笔记本中使单元彼此独立

问题描述

我想进行一些独立的计算，所有这些计算都在jupyter笔记本的自己的单元格中-如果愿意，每个单元格都具有自己的主要"功能.目前看来，所有包含Python的单元的并集代码本质上是一个大型Python程序.

I would like to have a few independent computations, all them in their own cells in a jupyter notebook -- each cell having its own "main" function if you will. Currently it looks like the union of all cells containing Pythoncode is essentially one big Python program.

简而言之，我要问Jupyter版本的这是Mathematica的问题.

In brief I am asking a Jupyter version of this question for Mathematica.

推荐答案

在单元格中定义的变量成为全局命名空间中的变量.要将变量隔离到本地范围，请将其放入函数中:

Variables defined in cells become variables in the global namespace.To isolate variables to a local scope, put them in functions:

In [1]:

    def foo():
        x = 1
        return x
    foo()

In [2]:

    def bar():
        x = 2
        return x
    bar()
