title: Can't convert a list of strings to floats
body: <p>My program is supposed to read a text document with a bunch of numbers and make a list of only the positive numbers. I can't convert the strings from the text document to a float so i can't determine if they are postive.</p>
  
  <p>I linked a screenshot because my copy paste is buggy.</p>

  <p>Without the number = <code>float(number)</code> , I get <code>['3.7', '-22', '3500', '38', '-11.993', '2200', '-1', '3400', '3400', '-3400', '-22', '12', '11', '10', '9.0']</code></p>
