Newbee Question

[HD1956]

This is probably a simple code. I am a truck driver who gets paid by
stops and cases. I am trying to figure out how to code my stop pay. I
get 40 cents per stop up to 22 stops, and $1.40 per stops after that.

[kyos...@gmail.com]

def calc(num):
if num < 23:
return 0.4 * num
else:
overtime = num - 22
x = 0.4 * 22
x += overtime * 1.4
return x

# Use your own brain next time

#!/usr/bin/env python

normalPay = 0.4
overPay = 1.4
normalLimit = 22

def calcPay(numStops):

pay = 0

if numStops > normalLimit:
pay = overPay * (numStops - normalLimit)
numStops = normalLimit

return pay + (numStops * normalPay)

if __name__ == "__main__":

print "Pay for 1 stops: %.2f." % calcPay(1)
print "Pay for 10 stops: %.2f." % calcPay(10)
print "Pay for 17 stops: %.2f." % calcPay(17)
print "Pay for 25 stops: %.2f." % calcPay(25)
print "Pay for 30 stops: %.2f." % calcPay(30)
print "Pay for 31 stops: %.2f." % calcPay(31)

Mike,

I wonder if we were both just duped into helping someone with their homework...

Sounds a bit like homework. Which usually isn't simply delivered here.

Can you show us some code you worked on, then we might suggest enhancements.

Yeah, it was fun to write anyway. Thanks for the compliment on the
code. I still consider myself a Python newbie, so it's good to know
I'm not trying to write it like Perl or VBScript anymore. ^_^

Wrong! Usually that happens pretty quickly here (as proven again in this
case). Not that it should, but only the seniors seem to detect lazy
learners.

I wish *I* could make a deal like that. I stop working all the

Thanks for the help. By the way I am trying to learn the python after
work and on weekends. If it was a dumb question, to this group, I will
not bother you all again.
Without help it will take me longer to learn. Thanks

Throw out an example of what you tried with an error message and/or
unexpected results. Ask particulars--this will keep you from giving
truck drivers a bad name.

Oh well since a few solutions have already been posted I thought I
might add another, just so you at the very least you have to do some
work making up your mind which one to choose. Using an incremental
approach just to be different ...

from decimal import Decimal

normal = Decimal('0.04')
over = Decimal('1.40)

def calcStopPay (stops) :
pay = Decimal('0.00')
while stops :
incr = normal if stops < 23 else over
pay += incr
stops -= 1
return pay

#testing:
for x in range(50) :
print "Stop pay for %s stops: $%s" % (x, calcStopPay(x))

oh boy ... and it should also be
normal = Decimal('0.40')

I really need to test before posting ...

It's not so much that it was a dumb question, but that it was asked in
a dumb way :-) You'll get the most help in this group if you can show
some evidence that you've had a go (the size of this thread ironically
trounces that argument of course ;-) .)

It's better to learn if people give you a critique of your own attempt
at the code, rather than looking at other peoples efforts. There's a
guide on how to ask good questions here: http://www.catb.org/~esr/faqs/smart-questions.html

For what it's worth, here's a gratuitous version using generators, and
one you should come back to once you've mastered the basics of Python:

def counter(std_rate, over_rate, limit):
stops = 0
while True:
stops += 1
wage = stops * std_rate + max(0, stops - limit) * (over_rate -
std_rate)
yield stops, wage

truck = counter(0.4, 1.4, 22)

for i in range(30):
print "Stopped %s times, with accumulated wage of $%s" %
truck.next()

Don't worry about it. There is also a list specifically for learners,
which you can find out about at

Welcome to the Python community!

Python 2.2.3 is three versions behind. Generators only work in 2.2 by
saying:

from __future__ import generators

And by default in anything from 2.3 on.
