Improvements for first script?

[alloydog]

Thanks for the tips. Didn't know about the style guide - Heading over to there ASAP.

For not using uppercase letters, then, measUnits would become meas_units.

I appreciate your comment about not needing to use "meas" everywhere, but I have reading issues and it helps me follow what's going on :)

I will also check out "f-strings". Are they related to g-strings

EDIT - updated script:

# Convert millivolts to engineering units
print("4-20 mA to Engineering units convertor")
print("")

def main():
    # Set engineering units and range
    meas_units = input("Enter the units of measurement: ")

    # Input minimum value of measurement range
    while True:
        try:
            meas_min = float(input("Enter the minimum measurement value: "))
        except ValueError:
            print("Must be a numeric value...")
            continue
        else:
            break
    
    meas_min2 = abs(float(meas_min)) # removes "minus" bit

    # Input maximum value of measurement range
    while True:
        try:
            meas_max = float(input("Enter the maximum measurement value: "))
        except ValueError:
            print("Must be a numeric value...")
            continue
        else:
            break

    # Display measurement range
    meas_range = float(meas_min2) + float(meas_max)
    print(f"Measurement range is {meas_min} to {meas_max} {meas_units}")
    
    # Input measured value
    while True:
        try:
            raw_value = float(input("Input mV value: "))
        except ValueError:
            print("Must be a numeric value...")
            continue
        else:
            break

    # Calculate measured value
    step1 = float(raw_value) - 400
    step2 = step1 / 1600
    meas_value = (step2 * meas_range) - meas_min2
    output = round(meas_value,2)
    print("Measured value is {} {}".format(output, meas_units))

    restart = input("Do you want to convert another value? Y/N: ")
    print("")
    if restart.lower() == 'y':
        main()
    else:
        print("Goodbye")

main()
