Python将exec与自定义全局变量结合使用

Question

I would like to create a simple python shell. So right now I am stuck on executing the code. The question is, is there a way to run exec with custom globals ? Thanks

You can pass custom global dictionary as follow:

a, b = 1, 2
exec('print(a+b)', {'a': 5, 'b': 5}) # prints 10
