Dude you rock! Keep up the good work. Very helpful and love your teaching style. Cheers from Australia!

Your programme can't handle decimals because you treated the price as an integer, if you had simply used the float() function instead of int() wouldn't that surely have fixed the problem?

Thank you

i could get the same code with normal input method, I wonder y do we need to use the stdin method????

print('what was your meal price: ?')
meal=int(input())
print('how much do you want to tip: ?')
tip=int(input())
final_tip= meal* tip /100
print('the amount you need to tip is {} dollars'.format(final_tip))

Why do i get the error "stdin" not defined? I wrote the code just like you did, I'm using python 3.9

What is difference between
price = int(input()) and price = int(sys.stdin.readlines())

does anyone know how to use text with sys.stdin.readline ??

mikailrizvi

wat about raw_input :p haha - we just started learning python in softwaredevelopment and i already have a problem :(

We need to create a class "Fractions" which is called by a other class named "Unit_fractionSubtraction" ( a Unit-test class)

-> The problem is we cant change the given class "Unit_fractionSubtraction" and make it work with our Fraction class.
It has following "setUp" method:

def setUp(self):
self.b = Fraction(3, 2)
self.b2 = Fraction(self.b) #gives a "Fraction" object as param. ..???
self.b3 = Fraction((4, 2)
pass

How can i make the constructor __init__ make that working that he can accept 2 values or a object. Its not like in Java where i can define multiple constructors :( help please im already stuck in the first Homework haha!
KEEP UP THE WORK !
