When you have a piece of code you want to run x number of times, then code within that code which you want to run y number of times, you use what is known as a nested loop. In Python, these are heavily used whenever someone has a list of lists-an iterable object within an iterable object.1  Early exits.f you've done any programming before, there's no doubt you've come across a for loop or an equivalent to it. In Python, they work a little differently. Basically, any object with an iterable method can be used in a for loop in Python.
If the result is abnormal, it is typically followed up with a fasting blood glucose test or a GTT. Glucose blood tests are also used to screen pregnant women for gestational diabetes between their 24th and 28th week of pregnancy.
To check blood glucose levels, a few different tests are available. One is the fasting blood test, or FSB, which is performed most often first thing in the morning before the patient eats breakfast.The two-hour postprandial test is done exactly two hours after eating a meal.The RBS, or random blood sugar test, is done at any time of day, regardless of when the last meal was eaten.ne is the fasting blood test, or FSB, which is performed most often first thing in the morning before the patient eats breakfast.
