actually it is int(x=0). Python is case sensitive!

actually comparison uses ==. x==0 would yiels True or False. Note again 
case is important.

Just not clearly understanding.

When you define a function you can make a parameter optional by the 
syntax parameter = default value.

int(x=0) thus is shorthand for saying "if you don't provide a value for 
x it will be assigned the value 0.

You could have discovered this by reading the docs. "Convert a number or 
string x to an integer, or return 0 if no arguments are given."
