Gotchas

Statements that precede code blocks (if, def, for, while, ...) end with a colon. def mean( x ) : s = 0.0 for i in x : s += i return s / l e n ( x )

Gotchas

Statements that precede code blocks (if, def, for, while, ...) end with a colon. def mean( x ) : s = 0.0 for i in x : s += i return s / l e n ( x ) Loop variables retain their state after the loop is finished (so if you want to reuse the variable, you need to reinitialize it).

Mean

def mean( x ) : s = 0.0 for i in x : s += i return s / l e n ( x ) def mean( x ) : return sum( x )/ f l o a t ( l e n ( x ))
