#1) local vars live in functions #1) global vars work anywhere 
       
#2) def f(x): root=sqrt(x) return (root+1)/(root-1) f(2) 
        
\newcommand{\Bold}[1]{\mathbf{#1}}\frac{\sqrt{2} + 1}{\sqrt{2} - 1}
\newcommand{\Bold}[1]{\mathbf{#1}}\frac{\sqrt{2} + 1}{\sqrt{2} - 1}
#3) def factorial(n): k=2 f=1 while k<=n: f=f*k k=k+1 return f factorial(10)
