title: How to count decimal places of a user-inputted float INCLUDING 0?
body: <p>I need to count the number of decimal places in a user-inputted float so that my code will not accept any number with more or less than 2 decimal places (the number is supposed to be a price). Here is my code:</p>
  
  <pre><code>        while(flag == True):
  
          try:
              price = input("Enter the price: ")
              price = float(price)
              flag = False
  
              #price must be positive
              if float(price) &lt; 0:
                  print("Invalid input for the new price.")
                  flag = True
  
          #check for 2 decimal places
          decimal = str(price)
          decimal = decimal.split(".")
          if len(decimal[1]) != 2:
              print("Invalid input for the new price.")
              flag = True 
  </code></pre>
  
  <p>As of now it is working, except if I enter a price like 6.50, where the last decimal place is a 0. For some reason it is not accepting any number that ends in 0 as 2 decimal places. How can I fix this?</p>
