title: order of parameters of function call of python
body: <p>Suppose I have a <code>function</code> with <code>10 args</code>:</p>
  
  <pre><code>def foo(arg1,arg2,arg3,arg4.....):
  </code></pre>
  
  <p>Sometimes, I need to call it with only <code>arg1</code> and another time <code>arg1, arg4</code>, or <code>arg4 , arg7</code>. </p>
  
  <p>My program doesn't specify the type of the function call. Does python have a way to help me?</p>
