如何在 IDE 之外使用 python 代码

Question

我已经实现了简单的 Mips 指令集汇编器，它仅支持 15 条输入指令集，例如 (add, and, or, nor, ori, lw, sw, jr, jal, sub, slt, sll,andi, addi, beq），程序是从用户那里获取输入的单条指令并在输出.txt文件中输出机器代码，我想做一些修改，首先是让用户输入多条指令，直到他想停止以及如何要为 .txt 文件中的下一条指令打印新行，我该如何在 IDE 之外使用该程序，我的意思是如果我想将汇编程序发送给某人直接使用它，我应该怎么做，在此先感谢。 这是代码：

inst = raw_input("enter your instruction operation:")

if ((inst[0] == 'a' and inst[1] == 'd' and inst[2] == 'd') or (inst[0] == 'a' and inst[1] == 'n' and inst[2] == 'd') or (inst[0] == 'o' and inst[1] == 'r') or (inst[0] == 'n' and inst[1] == 'o' and inst[2] == 'r') or (inst[0] == 's' and inst[1] == 'u' and inst[2] == 'b') or (inst[0] == 'j' and inst[1] == 'r') or (inst[0] == 's' and inst[1] == 'l' and inst[2] == 'l') or(inst[0] == 's' and inst[1] == 'l' and inst[2] == 't')):

Answer 1

就像@Bartlomiej Lewandowski 所说，Python 是一种解释型语言，您无需编译它就可以像使用 C 或 C++ 那样运行。您可以将脚本以 .py 文件的形式提交，并且您将其发送给的人可以通过以下调用从命令行运行它：

$ python script.py

假设文件名为 script.py。注意 $ 代表命令提示符。

或者，您可以将 hash-bang 添加到文件 #! /usr/bin/env python 的顶部并通过调用运行脚本

$ ./script.py

从命令行

Answer 2

Python 是一种解释型语言。要运行程序，您需要一个解释器。如果你在 linux 上，你可以通过在 cmd 中输入 python 来运行解释器。

如果您希望其他人在没有解释器的情况下运行它，有一些工具：py2exe，可以从 python 脚本生成可执行文件。

如果对方有python解释器，你只需要把脚本发给他们。
