在IDLE和Android App中运行，但不在Raspberry PI中运行

Question

我有一个在笔记本电脑上使用IDLE运行的程序，以及使用python应用程序在我的Android手机上运行的程序。当我尝试在Raspberry PI上运行它时，我收到一条错误消息“没有模块命名请求”。如果我从语句末尾删除请求，则会加载该部分。然后我得到了另一个错误，如9所示：

    Traceback (most recent call last):
    File "tibia.py", line 9, in <module>
    words=input('Enter the character name you wish to monitor...\n')
    File "<string>", line 1, in <module>
    NameError: name 'NAME' is not defined

我的代码如下：

import urllib.request
import time
import smtplib




#define and format character name
words=input('Enter the character name you wish to monitor...\n')
words=str.replace(words," ","+")
words=words.title()

#prepare email body
content=('This is an automated email notifying you that '+words+' is    online.')

#x for infinite loop
x=1
#adding anchors to character name
textToSearchFor = '=' + words + '"'




while x==1:
    try:
        site = urllib.request.urlopen('https://secure.tibia.com/community/?subtopic=worlds&world=Amera')
        HTML = site.read().decode("utf-8")


        if textToSearchFor in HTML:
          print(words + ' is online.')
          time.sleep(60)

       #send email
           mail=smtplib.SMTP('smtp.gmail.com',587)
           mail.ehlo()
           mail.starttls()
           mail.login('email','password')
           mail.sendmail('email@gmail.com','email@gmail.com',content)
           mail.close()

        else:
           print(words + ' is not online.')
           time.sleep(60)


    except:
        print('Error fetching character status.')
        time.sleep(60)
