def T2(x):
return x * 2
def dozen():
return T2('12')
def enestrate():
return T2(3)
print int (dozen()) + enestrate()
I know it prints 1218 but i dont understand the code and the whole concept ... I used python to run it
def T2(x):
return x * 2
def dozen():
return T2('12')
def enestrate():
return T2(3)
print int (dozen()) + enestrate()
I know it prints 1218 but i dont understand the code and the whole concept ... I used python to run it
Trace it out.
1)
//returns 2 times the number passed in
def T2(x):
return x * 2
2)
//return T2(12) = 12*2 = 24
def dozen():
return T2('12')
3)
//returns T2(3) = 2*3 = 6
def enestrate():
return T2(3)
now this call :
print int (dozen()) + enestrate()
Split it up and analyze it. See what you can come with.
Trace it out.
//return T2(12) = 12*2 = 24 def dozen(): return T2('12')
Split it up and analyze it.
I bet you didn't.
(Hint: T2('12')
returns '1212'
I assumed some things, because I don't know python. Thanks for correcting me.
It passed in a String... T2('12').. scripting languages support operator overloading (I think that's the term)
Had it passed in an int you would've been right
