title: How to pass arguments as tuple to odeint?
body: <p>I wanted to use odeint of scipy with a function</p>
  
  <pre><code>def func(y,t,a=123,b=456)
  </code></pre>
  
  <p>then use it as</p>
  
  <pre><code>odeint(func,y0,t)
  </code></pre>
  
  <p>If I want to change the values a and b using args</p>
  
  <pre><code>odeint(func,y0,t,args=(a=1,b=2))
  </code></pre>
  
  <p>It complains that arguments are not tuple. 
  It may be a very elementary question,
  how can I pass keyword arguments as a tuple?</p>
  
  <pre><code>odeint(func,y0,t,args=...?)
  </code></pre>
