title: from: can't read /var/mail/classes
body: <p>I am trying to write a python program, and trying to learn classes. My program is as follows:</p>
  
  <pre><code>class Account():
      def __init__(self, name, account_number, initial_amount, transactions):
          self.name = name
          self.no = account_number
          self.balance = initial_amount
          self.transactions = 0
  
      def deposit(self, amount):
          self.balance += amount
          self.transactions += 1
  
      def withdraw(self, amount):
          self.balance -= amount
          self.transactions += 1
  
      def dump(self):
          s = '$s, %s, balance: %s, number of transactions: %s' %\
               (self.name, self.no, self.balance, self.transactions) 
          print s 
  </code></pre>
  
  <p>In terminal, when i am in the folder the python program is located, I try to write from classes import Account to test my program, but the error code I get is: from: can't read /var/mail/classes. What does this mean, and how do I fix it?  </p>
