this is the code

import pydoc

def read_float(prompt):

    while True:

        try:

            number_text = read_text(prompt)

            result = float(number_text)

            break

        except ValueError:

            print('Enter a number')

    return result

read_float(1)

I am trying to use read_text function in python in this imageread_text program

but the in terminal i am getting a error of read_text is not defined

What you're looking at is not valid python code, unless read_text() is defined somewhere out of view. The function read_text() does not exist in standard python; rather, the built-in function input() serves that purpose instead. A proper implementation of that image you've provided is:

def read_float(prompt):                  # prompt is a string, e.g. "Enter a float"

    while True:                          # this is to continue trying if not-a-float is entered

        try:

            number_text = input(prompt)  # this prompts the user for input, and returns a string

            result = float(number_text)  # this tries to convert the string to a float

            break                        # exit this loop to return the float

        except ValueError:               # this is thrown by the previous line if number_text isn't able to be converted to a float

            print('Enter a Number')      # ask the user to try again

    return result

The result of running this function in my python console:

>>> read_float("Enter a float, please: ")

Enter a float, please: float

Enter a Number

Enter a float, please: 7.5

7.5
