预定义的Python函数无法运行，如果名称=主

Question

我是一名初学者程序员，我的目标是设计一个实用程序，可以接受短信命令并远程在我的主机上运行相应的功能。我正在使用各种工具（IFTTT，Dropbox，Twilio，Task Scheduler），但我一直在遇到一些麻烦。

最近我尝试了通过一个我已经命名为'main（）'的函数来运行主代码。然而，当我试图调用函数，命令行抛出一个错误：

Traceback (most recent call last): 
File "C:\Python_Files\WIP\Check.py", line 104, in <module> 
    main() 
NameError: name 'main' is not defined 

我会在这里发布我的代码的情况下（一些信息编辑出于安全考虑）：

#DESCRIPTION: 
#Check if C:/Users/Thermaltake/Dropbox/Remote_Control contains a .txt file 
#set count to corresponding integer 
#delete file 
#call function of corresponding integer 
#reset count 
#Set Task Scheduler to run this program every 5 minutes when idle.

TODO: 
Twilio not yet working. try different iterations of body and message. try assigning it to its own function 

subprocess failing to launch programs. research alternatives. SMTP is a possibility. 

possibly need to add Enter keystroke to the end of shutdown() and restart(). maybe even log in to log off. 

add 'send to-do list to phone' function. 

cleanup indentation and remove unnecessary modules 

add 'flvto' function 

add 'remote in' function. 


+ Version 1.1 7/6/17 + 

WORKING: 
subprocess.Popen('C:\Windows\system32\cmd.exe') 
webbrowser.open('http://somafm.com/player/#/now-playing/groovesalad') 
os.remove 
wakeup() 

NOT WORKING: 
subproces.Popen('C:\Python_Files\Sublime Text 3\sublime_text.exe') 
Twilio return message 
Task Scheduler: "Check_Dropbox on Lock" 

BUGS: 
IFTTT is buggy and sometimes unresponsive 
Task Scheduler to check file is too slow. Need something faster. (Possibly 'Watch 4 Folder') 
shutdown() waits til logon to initialize. 
restart() waits til logon to initialize.

任何帮助将非常感谢。请记住，我没有接受过CS的正式教育，但在今年秋天开始CS大学之前，我只是试图弄湿自己的脚。我只编程了大约3个月。

此外，如果此代码中的任何内容都可以做得更加优雅，我会很乐意接受建议。

从里面取出logmein()所以main()其在全球范围内。你得到的错误是因为当你从全局范围调用main时，它没有被定义。
