Package a Python Interpreter

uses Python's exec statement to make it easy to execute Python statements dynamically. If a python code is packaged for EXE, its original code is hard to change. A good solution is to import the corresponding library and then place the main program segment in a separate file to be executed by exec .

Now packs a simple Python interpreter, because it is an example that calls only one NumPy library.

• main.py interpreter

  import numpy as npif __name__ = = ' __main__ ': with open (' Cod e.py ', ' r+ ') as F:code=f.read () exec (code)  

• code.py interpreted content

 Code>a=np.array ([i=0for]) print (a) I in range (+): I+=iprint (i) Print (eval (' 1+2 ')) with open (' Run.cmd ') as F:pri NT (F.read ())  

With Pyinstaller package:

  pyinstaller-f-C main.py  

execution, we see that

can run as long as it is using a module that has been transferred into main.py (or a module alias). This achieves the effect of the wrapper interpreter .
