为什么我的代码打开另一个文件并处理错误异常？

Question

我正在尝试通过python在C：\ Users \ WilsonNg \ Documents \ Internship中运行文件（asana_get_user.py）。

但是，当我运行它时，出现属性错误：

错误消息

但是，由于某些原因，此代码完成后还会发生另一个异常错误：

异常错误

因此它打开了同一文件夹中的另一个文件（email.py），并创建了异常错误。

关于为什么引用我的email.py文件的任何想法？

asana_get_user.py

import asana

# replace with your personal access token. 
personal_access_token = '0/2c...'

# Construct an Asana client
client = asana.Client.access_token(personal_access_token)
# Set things up to send the name of this script to us to show that you succeeded! This is optional.
client.options['client_name'] = "hello_world_python"

# Get your user info
me = client.users.me()

# Print out your information
print ("Hello world! " + "My name is " + me['name'] + " and I my primary Asana workspace is " + me['workspaces'][0]['name'] + ".")

email.py

sending_msg = create_message(sender,sent_to,subject,message)

send_message()

Answer 1

请在email.py之前以if __name__ == '__main__':的身份登录subject = "This is a test subject"。

email.py在调用import asana时正在运行。

if __name__ == '__main__':
    subject = "This is a test subject"
    message = "This is a test content"
    sent_to = "test@test.com"
    sender = "test@test.com"

    sending_msg = create_message(sender,sent_to,subject,message)

    send_message()
