python "unexpected indent"

Question

我正在尝试运行此 python 代码，但我不断收到错误消息“意外缩进”。我不确定怎么了。间距似乎很好。有什么想法吗？

services = ['Service1']  
 for service in services:  
      try:  
           print service + '\t',  
           if 'notavailable' not in requests.get('some website' + service + '&username=' + username, headers={'X-Requested-With': 'XMLHttpRequest'}).text:  
                print 'Available'  
           else:  
                print ''  
      except Exception as e:  
           print e  

Answer 1

services = ['Service1'] 不符合你的 for 循环。

services = ['Service1']  
 for service in services: <-- unexpected indentation 

只需按如下所示排列您的代码。

services = ['Service1'] # need to line up with loop
for service in services: 
    try:
        print service + '\t',
        if 'notavailable' not in requests.get('some website' + service + '&username=' + username, headers={'X-Requested-With': 'XMLHttpRequest'}).text:
            print 'Available'
        else:
            print ''
    except Exception as e:
        print e

你的代码也是 python 2 语法而不是 python 3
