python What is wrong with this code?!? 0_o

[Brandon H Supervisor]

So I'm taking a Python class right now at my college and part of tonight's lab was creating this code using our knowledge thus far

even my teacher was stumped at what is wrong with the code

for some reason a couple of my variables are switching with each other in my output (parts price and tax) and I have no idea what is causing it

I already turned in the lab as my teacher said he wouldn't dock me points for it, I'm just curious as to what the problem is.

here is the lab question:

1. Joe?s Automotive
   

Create an application that displays the total bill for a customer?s visit to Joe?s. Your program must make use of functions. You determine what functions are needed. My Joe?s Automotive program used 12 functions, including the main (hint). My program also used 1 global variable to store the charge for parts. Your solution should use only 1 global variable or? the program can be written without using any global variables. Remember to add comments to your program.

Joe?s Automotive performs the following routine maintenance services:

• Oil change - $26.00
  
• Lube job - $18.00
  
• Radiator flush - $30.00
  
• Transmission flush - $80.00
  
• Inspection - $15.00
  
• Muffler replacement - $100.00
  
• Tire rotation - $20.00
  

Joe also performs other routine services and charges for parts and labor ($20.00 per hour).

You will need to determine what services the customer had completed. In addition, you will need to determine if any other routine services were performed other than those listed ? basically ask if other services were performed ? if yes, ask for the charge for parts and ask how many hours were expended doing those other routine services.

Your output should show the following where 999 are the dollar amounts and allow for a 2 decimal place precision.

Services and Labor Charge: 999.99

Parts Charge: 999.99

Tax on Parts (6%): 999.99

Total Charges: $9999.99

and here is the code I came up with:

#Joe's Automotive bill program
#Brandon Hash
charge = 0.0
def main():
    serviceCheck()
    cparts = parts()
    ctax = tax(cparts)
    total(ctax, cparts)
def serviceCheck():
    global charge
    service = raw_input ("Enter the service performed")
    if service == "oil":
	    charge = 26.00
    elif service == "lube":
	    charge = 18.00
    elif service == "rad":
	    charge = 30.00
    elif service == "tran":
	    charge = 80.00
    elif service == "ins":
	    charge = 15.00
    elif service == "muf":
	    charge = 100.00
    elif service == "tire":
	    charge = 20.00
    check()
def check():
    more = raw_input("Where there any more routine services performed?")
    if more == "yes":
	    serviceCheck2()
    else:
	    labor()
def serviceCheck2():
    global charge
    service = raw_input ("Enter the service performed")
    if service == "oil":
	    charge = (charge + 26.00)
    elif service == "lube":
	    charge = (charge + 18.00)
    elif service == "rad":
	    charge = (charge + 30.00)
    elif service == "tran":
	    charge = (charge + 80.00)
    elif service == "ins":
	    charge = (charge + 15.00)
    elif service == "muf":
	    charge = (charge + 100.00)
    elif service == "tir":
	    charge = (charge + 20.00)
    check()
def labor():
    global charge
    tlabor = input ("How many hours of were put into the car?")
    charge = charge + (tlabor * 20.00)
def parts():
    yparts = raw_input("Were any parts needed?")
    if yparts == "yes":
	    cparts = input("Enter the ammount for those parts.")
    else:
	    cparts = 0.0
    return cparts
def tax(cparts):
    global charge
    ctax = ((charge + cparts) * .06)
    return ctax
def total(cparts, ctax):
    global charge
    print "Receipt:"
    print
    print "Services and Labor:  $ %.2f"% charge
    print "Parts Charge: \t \t $ %.2f"% cparts
    print "Tax: \t \t \t \t $ %.2f"% ctax
    print "Total: \t \t \t \t $ %.2f"% (charge + cparts + ctax)
main()
[/CODE]

if you need any more info let me know, I'm completely stumped at what the problem is

here's the python file as well

lol.

Look at the argument order of total() in the declaration, then in the call.

lol wow, I feel derp now :p

both me and my teacher kept looking over that for like 15 minutes, I can't believe we overlooked that lol :D

thanks for the help jkenn99, I guess it's just been a long day
