the code is :

def maxnum(a,b,c):
if a>=b and a>=c :
return a
elif b>=a and b>=c :
return b
else :
return c

a = input("number 1 : ")
b= input("number 2 : ")
c= input("number 3 : ")
print(maxnum(a,b,c))

[serene echo]

!e

def maxnum(a,b,c):
    if a>=b and a>=c :
        return a
    elif b>=a and b>=c :
        return b
    else :
        return c

a,b,c = 1,2,3
print(maxnum(a,b,c))

@serene echo :white_check_mark: Your 3.12 eval job has completed with return code 0.

3

[minor flame]

return max((a, b, c))

[serene echo]

what makes you think it doesn't work?

[serene echo]

presumably this is an assignment to help them learn how to code it themselves

[placid shell]

It works only when a and b are the biggest

but with c there is a problem

[serene echo]

what should this have returned?

[placid shell]

3

[serene echo]

it did

what test case did you try?

[placid shell]

I just put 39,10 and 49

[serene echo]

and what did it output?

[placid shell]

39

but wait now it works

are you sure you didnt change anything ?

[serene echo]

I'm guessing it actually returned "39"

notice the quote marks

that means that it's a string

[placid shell]

yes

[serene echo]

you can compare strings in python with <, but they compare differently than numbers

!e

print( 2 < 11 )
print( "2" < "11" )

[mild owl]

@serene echo :white_check_mark: Your 3.12 eval job has completed with return code 0.

001 | True
002 | False

[serene echo]

strings are compared lexicographically, (like an extended alphabetical order)

[placid shell]

ok I see but how can this impact a number

[serene echo]

input always returns a string

if you want to use user input as something other than a string, you'll need to convert it yourself

[placid shell]

oooooh I understood

so I add int()

or float()

before input

[serene echo]

exactly
