- Python is created by Guido van Rossum in 1991. The language is designed for the issue of code readability. Its syntax is easy and you could write clean code with this programming language. You could find macOS, Windows, Linux as interpreters fur Python language. There are two versions of it: Python 2 and Python 3.
- Python language has extended advantages. It includes third-party modules to help your program. There are extensive supportive libraries such as Numpy and Pandas out there. It is open-source and easy to learn. It is a high-level language that you can learn effortlessly.
- Python is a great language to generate functional, operative programs. You can create GUI based applications, Web frameworks and applications, Enterprise and Business Applications, Operating Systems, Language Development, and Prototyping programs. Many organizations such as Google, Yahoo, Youtube, Mozilla, Dropbox, Microsoft, and others use Python as their highly used programming language.
Python 3 Basics
Print(“Some text”)
You could use print for showing text or number and you can do some calculations on print also you can show multiple variables on print():
Print(“text”,number,another variable)
Such that, you could see other variables and test your applications on important lines. There is also a list structure and other data structures are presented in Python such as assets, tuples, and dictionaries.
Contrary to Java and C languages, you could add various elements into a list with append function like this:
numList = [ ]
numList.append(“Number 1”)
numList.append(12342)
numList.append([1,2,4,5,2])
Various types of elements could be added to the list as shown. That way you can store many different variables on the same data structure if you want to work on the same list over and over with different functions but generally, other patterns are selected to apply programming solutions for problems. You can take user input such that:
name = input(“Enter your name: “)
print(“Hello, is your name” + name + “?”)
Like these, we can use python for getting user information or many diverse options on the desktop. There are different architectures for web and production. Nonetheless, these structures are important to understand the general logic flow between code bodies, classes, and functions. There are other structural elements such as classes, functions on python. These are used for not repeating the code and writing clean code to solve issues in a fast way.
Basic Calculator
To create a basic calculator we can form some functions then we could use them for mathematical operations. We can see the program like that:
import re
userInput = list(map(str, input("Enter a multiple value: ").split()))
def calculation(Input):
result = Input[0]
for string in userInput:
if “+” in string:
result += int(re.findall(r'\d+',string))
elif “-“ in string:
result -= int(re.findall(r'\d+',string))
elif “*“ in string:
result *= int(re.findall(r'\d+',string))
elif “/“ in string:
result -= int(re.findall(r'\d+',string))
return result
calculation(userInput)
This could be a program structure for a calculator. You could use the diverse system and create a webpage for the calculator program. However, you should develop further for usage because there are lots of calculators online.
There are lots of development frameworks on python such as Kivy, Django, Flask, Tkinter. These are all developed for different purposes. These purposes could be seen as mobile development and desktop programming development. Thus, you could have so many options with the Python programming language. There are great websites that may teach python to you and you can start a data science career also with datacamp or similar youtube channels that serve as learning material.
You could learn dynamical programming, functional programming, data science paradigm python calculations, and other things to improve your skill level. Python language is very helpful and useful for businesses. When you use python on kaggle or data science tasks, probably functional usage will be a valid paradigm for your purpose.
