nested-loops

How do I get out of nested for or loop in vb.net? I tried using exit for but it jumped or breaked only one for loop only. How can I make it for the following: for each item in itemList for each item1 in itemList1 if item1.text = "bla bla bla" then exit for end if end for end for Unfortunately, there's no exit two levels of for statement, but there are a few workarounds to do what you want: Goto . In general, using goto is considered to be bad practice (and rightfully so), but using goto solely for a forward jump out of structured control statements is usually considered to be OK, especially if

here is my code: def f(x): def g(n): if n < 10: x = x + 1 g(n + 1) g(0) When I evaluate f(0), there would be an error "x referenced before assignment". However, when I use "print x" instead of "x = x + 1" , it will work. It seems that in the scope of g, I can only use x as an "use occurrence" but not a "binding occurrence". I guess the problem is that f passes to g only the VALUE of x. Am I understanding it correctly or not? If not, can someone explain why the left side of "x = x + 1" is not defined before reference? Thanks You are understanding it correctly. You cannot use x to assign to in a

For a given input N, how many times does the enclosed statement executes? for i in 1 … N loop for j in 1 … i loop for k in 1 … j loop sum = sum + i ; end loop; end loop; end loop; Can anyone figure out an easy way or a formula to do this in general. Please explain. Grijesh Chauhan First, I written a C code to generate sum: int main(){ int i =0, k =0, j =0, n =0; int N =0; int sum =0; N =10; for (n=1; n <= N; n++){ // unindented code here sum =0; for (i=1; i<=n; i++) for (j=1; j<=i; j++) for (k=1; k<=j; k++) sum++; printf("\n N=%d sum = %d",n, sum); } printf("\n"); } Simple compile and generate

Wrote this function in python that transposes a matrix: def transpose(m): height = len(m) width = len(m[0]) return [ [ m[i][j] for i in range(0, height) ] for j in range(0, width) ] In the process I realized I don't fully understand how single line nested for loops execute. Please help me understand by answering the following questions: What is the order in which this for loop executes? If I had a triple nested for loop, what order would it execute? What would be equal the equal unnested for loop? Given, [ function(i,j) for i,j in object ] What type must object be in order to use this for loop
