Python – Working With Files

In this example of Python working with files, we’ll look at the built-in Python tools for working with files: opening / closing, reading, and writing. Until now, we only worked with objects stored in the computer’s RAM. That is, after the completion of the program, all our actions were deleted. Using our sample, you will learn how to work with files in Python, that is, to save the state of the program in a file on the hard disk.

Before you start working on your assignment, you should read through our sample. You can use our sample on Python write to file, as well as for doing any other tasks easily. If you don’t know how to complete your assignment, visit our blog to find the sample that you need. We have examples for tasks of different disciplines. Once you read, for example, the following sample, you will have a clearer understanding on how to do your own task in Python. Continue reading

Sample of a Python User Defined Function

In the following sample, we are going to talk about Python user defined function. A function in Python is an object that takes arguments and returns a value. A function is a block of organized, reusable code that is used to perform a specific task. Functions provide better modularity of the application and significantly increase the level of code reuse. There are some rules for creating functions in Python. You will learn about these rules if you read through the following sample.

We advise all students who are starting to study programming to read it through. Also, you can find examples of completed assignments in other disciplines. After you read our sample, you will be able to work with user defined functions in Python. You will see that such functions can be easily created by you. So, don’t wait anymore and read the following example – it will surely be helpful for you.

Detailed Python String Format Example

Sometimes (more precisely, quite often), there are situations where you need to make a string, substituting in it some data obtained during the execution of the program (user input, data from files, etc.). Data substitution can be done by formatting strings. Formatting can be done using the % operator, and the format method. The format method is the most correct, but you can often come across a program code with string formatting in the form of the operator %. If you read through the following Python string format example, you will easily complete your own assignment.

The Python string functions example that you can find below was completed by an expert in programming. Why do you need this sample? Such tasks are often assigned to students – that’s why we have decided to help you with this problem. If you need help with other types of assignments, you can check out our blog to find more samples. Continue reading

Look at This Python GUI Example

One attractive feature of Python is the simplicity, speed, and flexibility in creating applications with a graphical user interface (GUI). This advantage is associated not only with a large number of supported graphic libraries: Tkinter, PyQt, PyGTK, wxPython, Pygames, etc. The main reason is the interpretive nature of the Python platform; because of the availability of Python code, the appearance of the graphical application can always be changed or supplemented. And the entire interface from the Python code to the actual implementation of the GUI is hidden inside the Python library modules. Check out our Python GUI example to know about more advantages of developing GUI applications in Python.

The Python GUI sample presented below was developed by an expert in programming. You will complete your own task much faster if you read through our example and get some ideas from it. Because of the ease of demonstrating the problem and its solution, any student can understand the example. The sample is available for you now, so enjoy reading! Continue reading

Java LinkedList Example for Beginners

The main purpose of the linked list is to provide a mechanism for storing and accessing an arbitrary amount of data. According to the title of the sample, this is achieved by linking the data together in a list. Before you go on to consider the Java LinkedList example, let’s recall how the data is stored in an array. The data in the array is stored in a continuous section of memory, divided into cells of a certain size. Access to data in cells is done by reference to their location – the index.

The following linked list implementation in Java example is a great way to learn more about the issue. Most students who study programming will find our sample helpful. If you read through our example, it will increase your chances of dealing with your own assignment much better. If you don’t know how to complete your task, the following sample will be the most appropriate way out. Continue reading

Check Out a Bolted Joint Calculation Example

A joint calculation is performed in the case where it is required to give a quantitative estimate of the degree of curvilinearity of the correlation relation, while determining the coefficient of determination r2 and the point of the empirical line. If you need to do some calculations, our bolted joint calculation example will help you.

Start doing your assignment from reading through our example of bolted joint calculations. After that, you can deal with your task easily. The results will be much better if you decide to use the example. It is necessary to understand the topic in order to complete the assignment successfully, and our sample can help with that. You can also check out other samples presented on our blog, which can help with assignments for different disciplines. Each of the examples is done by an expert in the field. Read through our example to deal with your joint calculations easily. Continue reading

A Promise Javascript Example for IT Discipline

Promises have already been written about a lot. This promise Javascript example is just an attempt to collect the most necessary uses in practice for using promises with sufficiently detailed explanations of how this works. First, you need to know several definitions. Promises are objects that allow you to arrange the execution of asynchronous calls. An asynchronous call is a function call where the execution of the main code stream does not wait for the call to end. For example, running an http request does not interrupt the execution of the main thread. That is, the query is executed, and immediately, without waiting for its completion, the code following this call is executed, and the result of the http request is processed after its completion by the callback function.

Next, we will consistently deal with the functioning while using promises in Javascript in the presented sample. Our expert has experience in dealing with such assignments, so you can be confident in its correctness. After you read through our example, you will know how to deal with your own assignment.

A Javascript Promise Example to Help You Out

Promise provides a convenient way to organize asynchronous code. In modern JavaScript, promises are often used, including implicitly, using generators. Promise is a special object that contains its state. First, it is pending, then it is either fulfilled (successful) or rejected (“done with an error”). On Promise, you can hang a callback of two types: onFulfilled, which is triggered when the promise is “successful,” and onRejected, which is triggered when the promise is in the “executed with an error” state. The method of using a promise is described in the following Javascript Promise example.

If you need to know how to use Javascript promises, then our sample will be helpful for you. Having read this example, you will be able to do your own assignment much faster and easier. At the end of completing your task, you will get the result you need. You can also find other samples on our site for different disciplines. The following example will be appropriate for the IT discipline. Continue reading
