Learn python programming: Technology has become so vast these days that it is difficult to spend a single day without the comforts provided by technology. The most important facility of technology is a computer.
What is a computer? Concept of programming
Computer
As we all know since the start, a computer is a machine that takes input, processes it into useful information, and provides the output. But that’s not quite all. Because a computer is a machine that performs different tasks according to the given instructions to it.
Program
The set of instructions given to the computer to solve a problem is called program or software. So, we can say that the command following of the computer depends on the program. A programmer programs a machine or writes different programs for the computer.
What is a programming language?
Language is the way of communicating with one another. Programming language is the way of communicating or interacting with the computer. In Addition, we write programs of the computer with the help of programming language. There are two types of programming languages:
Low-level language
Low-level languages are close to computer language. In other words, a computer can understand low-level languages easily. There are further two types of low-level languages:
- Machine language or binary language is the main language of the computer. It is the combination of 0 and 1.
- Assembly language is one step ahead of the machine language. It uses English-like letters known as pnemonics. These are pronounced as Ne-Monics.
High-level language
The type of programming language that is close to human and far from computer language is known as high-level language. In Addition, high-level languages are user friendly. These include many languages such as:
- C/C++
- C#
- COBOL
- BASIC
- PASCAL
- Python
What is python?
Python is a high level programming language used to write many different programs for the computer. In Addition, it is an advanced form of C/C++. It has many benefits such as:
- You can easily write code in python.
- It is more easy to modify.
- The code written in python follows a simple and easy syntax almost every beginner can understand.
There are many examples of python codes. But some python code examples are as follows:
a = 10
print (“the number is”, a)
The above code will print the desired number.
print (“get4luck provides different information on interesting topics.”)
The above line of code will display the written line on the screen.
Difference between source code and object code:
Source code is a code written in high-level language. Computer translates this code into low-level language. This translated code is called object code. Computers translate codes through language translators or language processors. There are three kinds of language translators:
- Compiler: Translates the set of instruction as a whole.
- Interpreter: Translates the code line by line.
- Assembler: Purposely used for the translation of assembly language.
Learn python programming
Programming in python is a lot more easier than other languages. As a beginner, you can easily learn programming in python. As a matter of interest, get4luck is providing the facility to learn python programming for beginners. All we have to do is to understand the syntax of python.
You can use Visual Studio Code for python programming. You can also learn python online by using the courses available on youtube.
Algortihm and pseudocode (Learn python programming)
Algorithm
A step-by-step procedure to solve a problem is called algorithm. Algorithms are easy to understand. They are short and written in simple English. An example of algorithm for making a cup of coffee:
- Take the required ingredients.
- Mix them in a cup of water.
- Heat the water and enjoy.
Pseudocode (learn python programming)
The sequence of steps that explains an algorithm more efficiently is called pseudocode. An example of pseudocode for the cup of coffee is:
- Take a cup of water and fill it with water.
- Collect the ingredients required to make a coffee.
- Heat the water up to a moderate level.
- Mix the ingredients in the cup of hot water and enjoy.
Algorithm for adding two numbers:
Now we will write an algorithm for writing two numbers. These can be:
- Start.
- Take two integers a and b.
- Add a and b i.e, sum = a+b.
- Display sum.
- End.
Learn python programming (basic syntax of python)
Now we need to learn the basic syntax of Python. It includes the initialization of a variable. A variable is a memory space to store a value. The syntax for initializing and storing a value in a variable is very easy in python. A single line can perform this task. In Addition, we don’t need to type multiple lines of code in order to initialise and assign a value to the variable.
variable = value
An example of the code in python is
a = 10
Python Program for adding two numbers (learn python programming):
Now we will gonna write a python program to add two numbers. It is very simple. All we need to do is to initialize two integers and add them. Watch this code below:
a = 10
b = 15
sum = a + b
print (sum)
The above code will add these two numbers and will display their sum on the user interface screen. In Addition, you can also execute this code by taking input from the user. All you have to do is to use the input function. See this example:
a = int(input())
b = int(input())
sum = a + b
print (sum)
The above code will take values from the user and will print the sum of the given values.
You can start with writing different calculations programs such as subtracting two numbers, multiplication of two numbers and even division of two numbers.
Area of circle ( Learn python programming)
Finding the area of a circle is very simple in python. This is the structure of the code that you will gonna write in order to find the area of the circle.
print (“Enter the radius:”)
r = int(input())
Area = 3.14 * r * r
print (“The area of the circle is”, Area)
In Addition, the above code can also be written in the following method:
r = int(input(“Enter the radius:”))
area = 3.14 * r * r
print (“The area of the circle is:”, area)
Yes its true, you can also display the statement of entering a number within the input function.
Data Types:
All of you might be wandering why get4luck is using int in the start. Basically, it is a data type used to initialize the type of data. Data types are used to specify the type of data in a program. In Addition, Different data types are used to represent different kinds of data.
- Int. is used to represent integer data types.
- float. is used to represent float data types. Float means numbers with decimal point in them.
- char. represents a single character in a value.
- string. is the combination of multiple characters. In Addition, Double quotes are used to represent a string data type.
Importance of learning programming:
We all know that this modern world is a world of technology and computer science. Almost every person has his own computer system, users are finding people who can write programs for their computer that can fulfil their needs. If you have a little bit how know about programming, In Addition, professionals will definitely hire you for the purpose of creating software that can meet their needs.
This modern world of computer science and technology wants the kind of people who are technically efficient. Every person is using the facilities of technology. The demand of a programmer is extremely higher than you think. You can also acknowledge your skill online. Use online platforms such as fiver, upwork to freelance your programming skill.
This was all in today’s article, you will learn more about programming in python afterwards. We will discuss about the bugs and errors in the program. Also get4luck will tell you about the basic operators used in the programming. Escape sequences play a vital role in programming, we shall discuss about them as well. Types of operators used in programming, In Addition, these are mathematical operators but different operators have different functions in programming.
