The loop starts with the For statement, which initializes the value of i to 1 and sets the loop to run while i is less than or equal to 10. The Step 1 argument specifies that the loop should increment i by 1 each time. If i = 6 Or i = 8 Or i = 9 Then The If statement ...

In the above example, we have used for loop to execute a set of statements from 1 to 10 and increment each time by 1. The results are placed in the active worksheet cells A1 to A10 as shown below. So far we have only used single for loop. Now let’s try to use 2 For..Next ...
5$user->save();Typically, your Eloquent models will have auto-incrementing keys. However, if you wish to specify your own keys, set the incrementing property on your model to false.You may also use the create method to save a new model in a single line. The inserted model instance wil...
We can simply use Python For loop with the range() function as shown in the example below. Python 1 2 3 for i in range(2,10): print(i) Output: 2 3 4 5 6 7 8 9 By default, the increment in the range() function when used with loops is set to 1; however, we can change...
