hey guys what I need is piece of code that will do this:
if weight_p == (a letter, symbol, or anything other than a number)
     then print this and restart the function
Code: [Select]
def weight_for_p():
    global weight_p
    print "How much does your pork weigh(kg)?"

    weight_p = float(raw_input(">"))

Code: [Select]
def weight_for_p():
    global weight_p
    isnt_num=True  #loop once
    while isnt_num:    #loop if weight_p isn't a number
        print "How much does your pork weigh(kg)?"
        try:
            isnt_num=False #don't loop again
            weight_p = float(raw_input(">"))
        except ValueError: #if there is a value error, do this
            isnt_num=True       #loop again
            print "you suck at inputting numbers" #print that you suck at inputing numbers
A few questions:
What do you need this for? I'm not going to assume anything, but I hope you aren't just copy and pasting this into an assignment.
Why do all of your questions involve meat in some way? Am I the only one here who knows python?

thanks for the help, I'm doing some practice exercises for an IT class, I have to make a calculator for meat times and temperatures using the data the teacher gave me, I'm gonna study this to see how it works.
