title: isalpha() if statement being ignored python
body: <p>For some reason when I try to use isalpha() here in the if statement, it keeps being ignored and proceeds to the next line. If I use isdigit(), the code works as expected. I'm just trying to understand why isalpha() doesn't work here?</p>
  
  <pre><code>user_input1 = input("Enter the first number")
  if user_input1 == user_input1.isalpha():
      print ("Please use only numbers")
  user_input2 = input("Enter the second number")
  add_ints = int(user_input1) + int(user_input2)
  print (user_input1,"+" ,user_input2, "=", add_ints)
  </code></pre>
