Product Information

One of the top choices for kitchen countertops is granite. This material is a popular option that is durable and tough, allowing the granite to stand up to impact and abrasive damage. Additionally, this material is resistant to heat, making it an ideal choice for the kitchen. my_enumerate() takes two arguments, sequence and start. The default value of start is 0. Inside the function definition, you initialize n to be the value of start and run a for loop over the sequence. If you want a truly unique kitchen, concrete may be a good choice for your countertops. Due to the heavy weight of the material, concrete countertops are usually cast in forms right in your kitchen for custom installation. Though, it's necessary to note that this custom work does come at a higher price than other popular countertop options. Using string slicing here, you give the starting index 1, which corresponds to the second element. There’s no ending index after the first colon, so Python goes to the end of the string. Then you add the second colon followed by a 2 so that Python will take every other element. The wood is tough and durable, allowing it to stand up to years of use without failing. However, the fibrous nature of wood means that the surface of the countertop can become scratched, stained, or even burned. You can sand and reseal the wood about once every two to three years or as necessary to restore the original appearance of the countertop.

Putting in a ceramic tile countertop is an inexpensive option for the kitchen. It's hard, durable, and resistant to heat, though the size of each tile can impede the functionality of the countertop, making it more difficult to prepare food and keep clean. In Python, a for loop is usually written as a loop over an iterable object. This means you don’t need a counting variable to access items in the iterable. Sometimes, though, you do want to have a variable that changes on each loop iteration. Rather than creating and incrementing a variable yourself, you can use Python’s enumerate() to get a counter and the value from the iterable at the same time! Just like with a normal for loop, the loop variables can be named whatever you want them to be named. You use count and value in this example, but they could be named i and v or any other valid Python names.Calling next() again on enum_instance yields another tuple, this time with the count 1 and the second element from values, "b". Finally, calling next() one more time raises StopIteration since there are no more values to be returned from enum_instance. def even_items ( iterable ): ... """Return items from ``iterable`` when their index is even.""" ... values = [] ... for index , value in enumerate ( iterable , start = 1 ): ... if not index % 2 : ... values . append ( value ) ... return values ... Copied! With this example, one common bug that can occur is when you forget to update value at the beginning of each iteration. This is similar to the previous bug of forgetting to update the index. This is one reason that this loop isn’t considered Pythonic. Q2.

Stainless steel is commonly used in commercial kitchens due to the nonporous construction that makes it easy to keep clean. This is one of the types of countertops for the kitchen that resists mold, mildew, and staining, though the longer you leave a splash or spill, the more difficult it is to clean. A counter circuit is usually constructed of several flip-flops connected in a cascade. Counters are a very widely used component in digital circuits, and are manufactured as separate integrated circuits and also incorporated as parts of larger integrated circuits. for count , value in enumerate ( values , start = 1 ): ... print ( count , value ) ... 1 a 2 b 3 c Copied! def my_enumerate ( sequence , start = 0 ): ... n = start ... for elem in sequence : ... yield n , elem ... n += 1 ... Copied! Q1. Consider the partial implementation of a 2-bit counter using T flip-flops following the sequence 0-2-3-1-0, as shown belowSimilar in price to granite, marble is a high-end kitchen countertop material that is known for its aesthetic appeal. Marble comes in a wide range of colors, each with marble veining or naturally occurring pattern made from mineral deposits, making it an excellent option for anyone that wants a unique countertop design.

seq = list ( range ( 1 , 11 )) >>> print ( seq ) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >>> even_items ( seq ) [2, 4, 6, 8, 10] Copied! By using zip(), you can iterate through first, second, and third at the same time. In the for loop, you assign the element from first to one, from second to two, and from third to three. Then you print the three values. Hence 0000(init.) -> 0001(A1 and A3=0)->0010 (A1 and A3=0) -> 0011(A1 and A3=0) -> 0100 ( A1 and A3=1)[ clear condition satisfied] ->0000(init.) so it goes through 0->1->2->3->4 And we see Q3 and Q1 are 1 here, if we give NANDof these two bits to clear input then counter will be clear at 10 and again start from beginning.Finally, you create two lists from my_enumerate(), one in which the start value is left as the default, 0, and one in which start is changed to 1. In both cases, you end up with a list of tuples in which the first element of each tuple is the count and the second element is the value from seasons.
