Returning two variables?

[shycat518]

Okay, is it possible to return two variables in one function?

[parthpatel]

Yes it is possible to return two variables from a single function

def A(self):
    z= 1
    c=  2
    return z,c 

it will return (1,2) as a tuple

def A(self):
z= 1
c= 2
return z,c

it will return (1,2) as a tuple

before barton comes, i wish to say, pls use code tags for the code. :)

Excellent reply, parthpatel.

But I must point out that this syntax is for a class method and sould include the class header:

class A_Class
    def A(self):
        z= 1
        c=  2
        return z,c 

And would be called as:

anInstance = A_Class()
print anInstance.A()

For a function use:

def A():
    z = 1
    c =  2
    return z, c
 
print A()
## OR ##
a, b = A()
print a, b

Next time, there is a panel on the right and side called "REPLY GUIDELINES" that shows what CODE tags look like.

Your editor has a # button that is very handy for this. It works best with the "Enhanced Mode" radio button selected.

Thanks for helping out in the Python Forum on TheScripts.com.

Awesome, thanks. :)

That's good to know I was at least doing it half right. :) I didn't try the ().

Since I'm still new at Python and am having tons of problems with more than one functions, I've been playing around with them.

Here's program I've been working with. It, of course, doesn't work. According to my boyfriend I still don't understand passing and returning variables. :P At least I'm trying. . .

def main():
    askfor()
    hours()
    pay()
 
def askfor():    
    hours = input("How many hours were worked? ")
    rate = input("What is the pay rate? ")
    print "Pay rate = $", rate
    return (hours,rate)
 
def hours():
    reghr = 40
    print "Regular Hours = ", reghr
    overtime = hours - 40
    print "Overtime hours ", overtime
    return (reghr, overtime)
 
def pay(rpay, otpay):
    pay = (40 * rate)
    print "Regular Pay = $",pay
    otpay = (1.5 * rate)*(overtime) 
    print "Overtime Pay = $", otpay
    total = pay + otpay
    print "Total Pay = $", total 
    return (pay, total)
 
main()

Here's the same program using one funtion that works. . . I want the same output as this one but with the 4 function one. You would think that since I can get everything to work on the one function program, I could divide it up easier.

def main():
    hours = input("How many hours were worked? ")
    rate = input("What is the pay rate? ")
    print "Pay rate = $", rate
    reghr = 40
    print "Regular Hours = ", reghr
    overtime = hours - 40
    print "Overtime hours ", overtime
    pay = (40 * rate)
    print "Regular Pay = $",pay
    otpay = (1.5 * rate)*(overtime) 
    print "Overtime Pay = $", otpay
    total = pay + otpay
    print "Total Pay = $", total 
main()

You are very close. You need to assign funcion results to variables, then pass them to the next function:

def main():
    h, r = askfor()
    reg, ot  = hours(h)
    pay(r, reg, ot)
 
def askfor():    
    hours = input("How many hours were worked? ")
    rate = input("What is the pay rate? ")
    print "Pay rate = $", rate
    return (hours,rate)
 
def hours(hours):
    overtime = 0
    if hours > 40:
        overtime = hours - 40
        hours = 40
    print "Regular Hours = ", hours
    print "Overtime hours ", overtime
    return (hours, overtime)
 
def pay(rate, reg, overtime):
    pay = (reg * rate)
    print "Regular Pay = $",pay
    otpay = (1.5 * rate)*(overtime) 
    print "Overtime Pay = $", otpay
    total = pay + otpay
    print "Total Pay = $", total 
    return (pay, total)
 
main()

I threw in the test for a case where hours are less that 40.
Also, your use of print adds a space between '$' and the variable evaluation.
Here are a couple of ways to get rid of that:

    print "Overtime Pay = $" + str(otpay)
# or (more advanced, but worth learning)
    print "Overtime Pay = $%.2f" % otpay
