logic behind this:

Question

def max(x, y):
if x >=y:
return x
else:
return y

print(max(4, 7))
z = max(8, 5)
print(z)

Can someone please explain this code line to line

Answer 1

Anil Gurjar def is a identifier which use to define function so here max is a function which has two parameters x,y and returns max value.

Here if x will be greater than or equal to y then max will be x otherwise y

So for this max(4, 7) max value will be 7
for max(8, 5) max value will be 8

Here z = max(8, 5) which will assign max value to another variable z

Answer 2

Anil Gurjar, please avoid using names like max that are also used for python builtin functions *max()*. In some cases this can lead to errors, that are really hard to catch.

Answer 3

in print(max(4,7)) you are printing the returned value when function is called
in z=max(8,5)
z stores the value returned by calling function
and after you print z(it's value)

Answer 4

The function is returning a number which is greater than the other. But if x and y are both equal then it will return x.
Now, let's go to the second half,
Since, the function is just returning a number
We can either assign it a variable or directly print it:
x = 5
print(x)
And
print(5)
Are the same thing!

I hope this helped you!
