title: python- with an undetermined tuple (str), how to find if a letter is in each one of the strings
body: <p>So basically, the user is allowed to input any amount of strings that they want to when they call the function, as long as the it's a string and the strings are separated by commas and have quotation marks around them. For example: </p>
  
  <pre><code>  func("str1", "str2", "str3") 
  </code></pre>
  
  <p>I want to look at each one of these strings that they put in and see if it contains a specific character, like the letter 'a' for example. If they all contain the letter, I want to return true, if they don't, I want to return false. How can I look at each of the strings they put in (because there is no specified amount) and check?   </p>
