How do you take a users input as a float?

Question

I\'m running Python 2.7.10. I have the following code block from a program I\'m working on.

with open(\'inventory.txt\', \'r+\') as f:
  inventory = {}
  whi         


        

Answer 1

The short answer is to use float(raw_input('Price: ')), but it might be better to write a method to handle the inputing of floats (and retry until you get what you need).

def input_float(prompt):
    while True:
        try:
            return float(raw_input(prompt))
        except ValueError:
            print('That is not a valid number.')

then use the method

inventory[item] = input_float('Price: ')
