如何从Windows Shell启动python脚本？

Question

我想启动一个python脚本(file.py)

为此，我在Python解释器中复制了该文件的路径，但得到错误SyntaxError: unexpected character after line continuation character

我是初学者，这是到目前为止我发现的最简单的启动Python脚本的方法…如果你有更简单的方法我愿意接受小费...

谢谢

下面是我的Python脚本：

import os
import csv

ACCEPTED_MSG="""
Hi {},

We are thrilled to let you know that you are accepted to our 
programming workshop.

Your coach is {}.

Can't wait to see you there ! 

Thank you,

Workshop Organizers
"""

REJECTED_MSG="""
Hi {},

We are verry sorry to let you know that due to a big number
of applications we couldn't fit you at the workshop this time...

We hope to see you next time.

Thank you, 

Workshop Organizers
"""

path_to_file = "C:/Users/Julien/Downloads/data.csv"

file_exists = os.path.exists(path_to_file)

if file_exists:

    csv_file = open(path_to_file)
    csv_reader = csv.reader(csv_file, delimiter=',')
    next(csv_reader)

    for row in csv_reader:
        name, email, accepted, coach, language = row
        print (name, email, accepted, coach, language)

        if accepted =='Yes':
            msg = ACCEPTED_MSG.format(name, coach)
        else:
            msg = REJECTED_MSG.format(name)

            print ("Send e-mail to: {}".format(email))
            print("E-mail content:")
            print (msg)
csv_file.close()

Answer 1

如果你只想运行一个脚本，那么语法是(从你的system__shell，__not python shell)：

$ python path/to/your/script.py

如果想要在现有的python shell中执行，可以(在python shell中)运行：

>>> execfile("path/to/your/script.py")

Answer 2

你可以运行

python<version> <path>

示例：

Python3 test.py

从您的错误看，您似乎正确地运行了它，但代码包含编译错误。添加代码片段，这样我们就可以看到问题出在哪里

Answer 3

我无法从Windows控制台启动Python脚本，因为我没有添加变量PATH。

因此，我在YouTube教程后面添加了变量path：https://www.youtube.com/watch?v=uXqTw5eO0Mw

然后，当我试图启动脚本时，我得到了一个错误“没有找到这样的文件或目录”。这是因为我没有在脚本"C：\ ...“的路径中放一个空格。不是"C:\“

最后，我收到一条消息"python.exe无法找到'main‘模块“。这是因为我需要再次使用".py“扩展名保存我的脚本。
