POHow to convert a string to a float?
text
Body
copied!<p>I'm currently working on a program in Python and I need to figure out how to convert a string value to a float value.</p> <p>The program will ask the user to enter a number, and uses a loop to continue asking for more numbers. The user must enter 0 to stop the loop (at which point, the program will give the user the average of all the numbers they entered). </p> <p>What I want to do is allow the user to enter the word 'stop' instead of 0 to stop the loop. I've tried making a variable for stop = 0, but this causes the program to give me the following error message: </p> <pre><code>ValueError: could not convert string to float: 'stop' </code></pre> <p>So how do I make it so that 'stop' can be something the user can enter to stop the loop? Please let me know what I can do to convert the string to float. Thank you so much for your help! :)</p> <p>Here is some of my code: </p> <pre><code>count = 0 total = 0 number = float(input("Enter a number (0, or the word 'stop', to stop): ")) while (number != 0): total += number count += 1 print("Your average so far is: " , total / count) number = float(input("Enter a number (0, or the word 'stop', to stop): ")) if (number == 0): if (count == 0): print("") print("Total: 0") print("Count: 0") print("Average: 0") print("") print("Your average is equal to 0. Cool! ") else: print("") print("Total: " , "%.0f" % total) print("Count: " , count) print("Average: " , total / count) </code></pre> <p>Please let me know what I should do. Thanks. </p>
