Use yield statements to create generator functionsIf you have a function that returns a list and as you build up that list, you're only ever adding items to the end, you can probably turn that function into a g
Use a heavy-duty, grounded outdoor extension cord for plugging appliances and other items into the generator. You may be able to plug some devices directly into the generator, but since the generator has to be kept outside this is often impractical or impossible. Tip Store the fuel for your...
In this way, you can use the generator without calling a function: Python csv_gen = (row for row in open(file_name)) This is a more succinct way to create the list csv_gen. You’ll learn more about the Python yield statement soon. For now, just remember this key difference: ...
As you can see, a generator is created with the keyword def — just like any other function or method. Nothing new there. Next we use a for loop to iterate over some_value which is provided by the user. This is old hat, but the yield keyword is new and specific to generators. What...
Use this function with care, it may slow down your workbook considerably if used extensively. This is the case with all volatile functions. 3. Example 1 This example demonstrates how to use the RANDBETWEEN function. It has two arguments bottom and top, which determines the range or boundary ...
a model like theKOHLER 26 kW Home Generatorcan safely and immediately start on its own, preventing potential disasters like frozen pipes from happening whether you’re at home or not. Use this guide to learn how to use a generator to keep the lights (and much more) on when the power goe...
This may be a convenient way to avoid placing an otherwise unneeded function into the namespace. On the other hand, it may be a little harder for someone reading the code to determine your intent when you use lambda instead of defining a separate function. As is often the case, it’s ...
2. Placement of the Generator The placement of your generator is key to avoiding a dangerous situation. The right location depends upon the type of generator you have. If you have a conventional fuel generator, you must never use it indoors. Place the generator in a dry location outside tha...
The exhaust system handles toxic emissions to ensure safety and compliance with local regulations. Lubrication System Moving parts require lubrication. Regular checks and changes in oil are necessary for durability. Battery Charger The generator’s start function relies on a battery kept at an optimal...
How to use as a generator to draw water from the waves of the seas and lakes and the flow of the valleys and riversThe present invention is a method of pulling up the water by using the power of the waves and flowing water of the sea and lake, in detail, the current salt ...
