Answer:
When a Python script is running as a standalone program, the __name__ variable will be set to __main__.
Explanation:
Python does not have main( ) function like some other programming language. So, when a command is given the interpreter to execute a python program, the code that is indented least (that is level 0) is executed first.
However, before doing that, it will define a few special variables. __name__ is one such special variable. If the source file is executed as the main program, the interpreter sets the __name__ variable to have a value “__main__”. If this file is being imported from another module, __name__ will be set to the module’s name.
Answer:
Returned value: 2
Explanation:
Public int f(int k, int n) {
if (n == k)
return k;
else if (n > k)
return f(k, n - k);
else return f(k - n, n);
}
/////////////////////////////////////////////////////////////////////////////////////////
Trace of function calls,
f(6, 8)
f(k, n - k) -> (6, 2)
f(k - n, n) -> (4, 2)
f(k - n, n) -> (2, 2)
return k
Answer:
6 columns/items
Explanation:
<em>grid</em> starts off as an empty list ( [ ] ), so right now it has 0 items/columns.
After that, 3 new items ("frog", "cat", "hedgehog") have been appended to <em>grid</em>, it now has 3 items
Finally another 3 items are appended to <em>grid ("fish", "emu", "rooster"</em>), finally <em>grid</em> ends up with 6 items in total.
