WebThe function must compute and return the True Positive Rate (TPR, also called recall) and the False Positive Rate (FPR) (these are both scalar values) for each threshold value in the list that is passed to the function. The TPR will be plotted against the FPR in what is called the Receiver Operating Characteristic (ROC) curve.

WebMar 28, 2013 · 0. range (x) is evaluated only once i.e. when the loop begins, that is why modifying x inside the loop has no effect. However, in the first code clock, you change x to 2 in the inner, so the next time the inner loop is executed, range only gives (0,1). Edit: your first block of code is equivalent to. x = 5 for i in range (x) print i x = 2.
