Product Information

The modulus of a counter is the number of states in its count sequence. The maximum possible modulus is determined by the number of flip-flops. For example, a four-bit counter can have a modulus of up to 16 (2 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. 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. When an iterable is used in a for loop, Python automatically calls next() at the start of every iteration until StopIteration is raised. Python assigns the value it retrieves from the iterable to the loop variable.

In this example code, even_items() uses a list comprehension rather than a for loop to extract every item from the list whose index is an even number.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!

Concrete countertops can be color-tinted or may have decorative textures added to improve the look and feel of the material. It's scratch-resistant and heat-resistant, though the porous construction is vulnerable to moisture, bacteria, and staining. The nonporous engineered stone quartz comes in a wide range of colors and patterns, allowing you to choose the best design for your kitchen aesthetic. It's an easy-to-clean material that is resistant to mold, mildew, and bacteria, making it a great choice for the kitchen where food is prepared. 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.A go-to kitchen countertop option for many DIYers is laminate because it is an inexpensive choice that's relatively easy to install due to the lightweight design. Laminate is made of particleboard, resins, plastic, and pattern paper that has been seared together using a combination of heat and pressure.
