Help me debug programm

Question

I need count percent using lambda function. One test failed. I dont understand why?

price = int(input())
perc = int(input())

res = (lambda x,y:(x/100)*y)

print(res(price, perc))

Answer 1

Olga Belyavskaya ,

ok, i think the reason for the issue is that `x` and `y` are mixed up in the formula. should be:

...
res = (lambda x,y:(y/100)*x)
...

Answer 3

price = 100
percent = 7

res = (lambda x, y: (x / 100) * y)
print(res(price, percent)) #7.0

res2 = (lambda x, y: (y / 100) * x)
print(res2(price, percent)) #7.000000000000001

res3 = (lambda x, y: (x * y) / 100)
print(res3(price, percent)) #7.0

The lambda takes 2 arguments, the first is x, and second is y.
When you try to print it, you provide it with two argument, the first is price, and second is percent.
Therefore x becomes price, and y becomes percent.
If you provide the arguments in different order: first is percent, second is price, x will become percent and y will become price.

Answer 4

It is work! Thank you. Can you explain me please 'x' its price and 'y' its perc? So why we must 'perc' \\ 100?

Answer 5

What are variables x & y? Should they be price & perc?

[edit: turns out I don't know how to use lambda.... woops]
