title: question for using "if" with requirement of word+any integer
body: <p>here's my thought</p>
  
  <p>for some reason it must be in this kind of form</p>
  
  <pre><code>text=input("plz type:")
  constant=30
  if text == "!dollar "+**any integer**
      print(any integer*constant) 
  </code></pre>
  
  <p>How to make it work properly</p>
  
  <p>Is it possible to use "if" with this kind of requirement?</p>
  
  <p>and also get the integer on further calculation</p>
  
  <p>Thanks!!!</p>
