IndentationError: expected an indented block when use unicode
Question: I'm getting this error:

> IndentationError: expected an indented block when use unicode

but without:

    
    
    def __unicode__(self):
        return self.BankName
    

it work correctly.

My models.py:

    
    
    from django.db import models
    class Bank(models.Model):
        BankName=models.CharField(max_length=20)
        CardNum=models.CharField(max_length=20)
        def __unicode__(self):
            return self.BankName
    

when typing python `manage.py runserver`

    
    
    Validating models...

Please help me.


Answer: 
    from django.db import models
    class Bank(models.Model):
        BankName=models.CharField(max_length=20)
        CardNum=models.CharField(max_length=20)
        def __unicode__(self):
            return self.BankName
    

Please [read the Python tutorial sections on control structures, which
describes multi-level
indentation](https://docs.python.org/2/tutorial/controlflow.html).
