如何从IDLE交互式shell运行python脚本？

How do I run a python script from within the IDLE interactive shell?

如何在IDLE交互式shell中运行python脚本？

The following throws an error:

以下引发错误：

>>> python helloworld.py
SyntaxError: invalid syntax

10 个解决方案

#1

Built-in function: execfile

内置函数：execfile

execfile('helloworld.py')

It normally cannot be called with arguments. But here's a workaround:

通常不能使用参数调用它。但这是一个解决方法：

import sys
sys.argv = ['helloworld.py', 'arg']  # argv[0] should still be the script name
execfile('helloworld.py')

Deprecated since 2.6: popen

自2.6以来不推荐使用：popen

import os
os.popen('python helloworld.py') # Just run the program
os.popen('python helloworld.py').read() # Also gets you the stdout

With arguments:

有了参数：

os.popen('python helloworld.py arg').read()

---

Advance usage: subprocess

高级用法：子进程

import subprocess
subprocess.call(['python', 'helloworld.py']) # Just run the program
subprocess.check_output(['python', 'helloworld.py']) # Also gets you the stdout

With arguments:

有了参数：

subprocess.call(['python', 'helloworld.py', 'arg'])

Read the docs for details :-)

阅读文档了解详情:-)

Tested with this basic helloworld.py:

测试了这个基本的helloworld.py：

import sys
if len(sys.argv) > 1:
    print(sys.argv[1])

The IDLE shell window is not the same as a terminal shell (e.g. running sh or bash). Rather, it is just like being in the Python interactive interpreter (python -i). The easiest way to run a script in IDLE is to use the Open command from the File menu (this may vary a bit depending on which platform you are running) to load your script file into an IDLE editor window and then use the Run -> Run Module command (shortcut F5).

IDLE shell窗口与终端shell不同（例如运行sh或bash）。相反，它就像是在Python交互式解释器（python -i）中。在IDLE中运行脚本的最简单方法是使用“文件”菜单中的“打开”命令（这可能会有所不同，具体取决于您运行的平台）将脚本文件加载到IDLE编辑器窗口，然后使用Run - >运行模块命令（快捷键F5）。

#3

You can use this in python3:

你可以在python3中使用它：

exec(open(filename).read())

#4

Try this

尝试这个

import os
import subprocess

DIR = os.path.join('C:\\', 'Users', 'Sergey', 'Desktop', 'helloword.py')

subprocess.call(['python', DIR])

#5

execFile('helloworld.py') does the job for me. A thing to note is to enter the complete directory name of the .py file if it isnt in the Python folder itself (atleast this is the case on Windows)

execFile（'helloworld.py'）为我做的工作。需要注意的是输入.py文件的完整目录名称，如果它不在Python文件夹本身中（至少在Windows上就是这种情况）

For example, execFile('C:/helloworld.py')

例如，execFile（'C：/helloworld.py'）

#6

For example:

例如：

import subprocess

subprocess.call("C:\helloworld.py")

subprocess.call(["python", "-h"])

#7

To run a python script in a python shell such as Idle or in a Django shell you can do the following using the exec() function. Exec() executes a code object argument. A code object in Python is simply compiled Python code. So you must first compile your script file and then execute it using exec(). From your shell:

要在python shell（如Idle）或Django shell中运行python脚本，可以使用exec（）函数执行以下操作。 Exec（）执行代码对象参数。 Python中的代码对象只是编译的Python代码。因此，您必须首先编译脚本文件，然后使用exec（）执行它。从你的shell：

>>>file_to_compile = open('/path/to/your/file.py').read()
>>>code_object = compile(file_to_compile, '<string>', 'exec')
>>>exec(code_object)

I'm using Python 3.4. See the compile and exec docs for detailed info.

我正在使用Python 3.4。有关详细信息，请参阅compile和exec文档。

#8

In Python 3, there is no execFile. One can use exec built-in function, for instance:

在Python 3中，没有execFile。可以使用exec内置函数，例如：

import helloworld
exec('helloworld')

#9

In IDLE, the following works :-

在IDLE，以下工作： -

import helloworld

I don't know much about why it works, but it does..

我不太了解它为什么会起作用，但确实如此......

#10

I tested this and it kinda works out :

我测试了这个，它有点成功：

exec(open('filename').read())  # Don't forget to put the filename between ' '
