Converting string to float with Python 3.2
<p>The purpose of this program is to display the sum, average, max, and min of use based input.</p>

<pre><code>count=0.0
Sum=0.0
average=0.0
data=float(input("Enter a number or just ENTER to quit:"))
Min=data
Max=data

while data!="":
    count+=1
    number=float(data)
    Sum+=number
    average=Sum/count

    if data&lt;Min:
        Min=data
    if data&gt;Max:
        Max=data
    data=float(input("Enter a number or just ENTER to quit:"))

print(count,("numbers entered."))
print("Sum:",Sum)
print("Average:",average)
print("Min:",Min)
print("Max:",Max)
</code></pre>

<p>The problem is with line 20:
data=float(input("Enter a number or just ENTER to quit:"))</p>

<p>When i press ENTER to end the loop it says that it was unable to convert string to float and errors. What am I doing wrong ?????</p>
