fixed the issue. Will look into that further I want to have two if statements in a single block like this: ,
if $u is equal to $jmsa and $p is equal to $hsma
code :
if($u == $jsma && $p == $hsma){
if($u == $jsma || $p == $hsma){

it should still fix some issue Im a newbie to python , and I came across this particular code snippet to calculate the greatest slice in an sequence, however I simply cant seem to understand the following code , First off, the error in your code is an extra =. Working code:
code :
n = len(A)
best = A[0] 
for size in range(1,n+1): 
   cur = sum(A[:size]) 
   for i in range(n-size): 
      cur += A[i+size] - A[i] # <- what happens here?
      best = max(best, cur)

should help you out No.
If GradedCourse c(cVal, gr); throws an exception, nothing else inside the try block will be executed.

help you fix your problem With a specific arbitrary statement, no.
If you have to have granular undo like that, you're better off writing the items in the block using the Command pattern, stacking an undo operation for each operation as you proceed. If you get to the end and it's all OK, you wipe the stack, dropping all the undos; if you had an exception, you pop the undos off the stack one by one and execute them in reverse to restore the original state.

like below fixes the issue I'm writing programs for 2 years as a student. I'm just curious when the catch statements will appear. I tried everything to make my program output the statements inside the catch block but I fail. Any ideas? , You could throw new IOException like
code :
try {
    throw new IOException("Like this");
} catch (IOException e) {
    e.printStackTrace();
    System.err.println(e);
}
java.io.IOException: Like this
    at com.stackoverflow.Main.main(Main.java:8)
java.io.IOException: Like this
