title: list comprehension in python and its alternative
body: <p>The problem statement is to apply <code>isalpha, isdigit, isnumeric, islower</code> to a string. I want to use code that performs this operation. So far I came up with this </p>
  
  <pre>
  string='Ab65GH'
  any(eval(c.i for c in string) for i in "isalpha() isdigit() islower() isnumeric()".split())</pre>
  
  <p>The output can be formatted to look like a list of booleans joined by '\n'.
  Please provide solutions on how to improvise/complete the above code and your alternative approaches</p>
