It shows an error if no condition is given. Initialization If initialization is once done in the “for” loop, it never is repeated. If initialization is done while condition checking, then it is required each time when the loop iterates itself. Iteration Statement As the iteration statement ...
Other programming languages like C and Go don’t even have exception-handling mechanisms. So, for example, Go programmers are used to preventing errors using conditional statements, like in the following example: Go func SomeFunc(arg int) error { result, err := DoSomething(arg) if err !=...

ADAL for Python uses the exception AdalError to indicate that there's been a problem. MSAL for Python typically uses error codes, instead. For more information, see MSAL for Python error handling.API changesThe following table lists an API in ADAL for Python, and the one to use in its ...
Use a for loop when you know in advance how many times you need to iterate, and opt for a while loop when the continuation of the loop depends on a condition that is evaluated dynamically during runtime. Exception handling and StopIteration ...
