Programming & Problem Solving through Python (M3-R5.1)

Introduction

Python is an easy to learn, powerful programming language that combines the features of C and Java. 

( पायथन सीखना आसान, शक्तिशाली प्रोग्रामिंग भाषा है जो C और JAVA की विशेषताओं को जोड़ती है। पायथन का उपयोग करना सरल है। )

Python is a high-level language, which means that it is closer to human language than machine language. This makes it easier to read and write Python code, and it also makes it more portable, meaning that it can be run on different types of computers without having to be rewritten.

(पायथन एक उच्च स्तरीय भाषा है, जिसका अर्थ है कि यह मशीनी भाषा की तुलना में मानव भाषा के अधिक करीब है। इससे पायथन कोड को पढ़ना और लिखना आसान हो जाता है, और यह इसे अधिक पोर्टेबल भी बनाता है, जिसका अर्थ है कि इसे दोबारा लिखे बिना विभिन्न प्रकार के कंप्यूटरों पर चलाया जा सकता है।)

Here are some of the benefits of using Python:

• It is easy to learn and use.
• It is a general-purpose language, meaning that it can be used for a wide variety of tasks.
• It is a free and open-source language.
• It has a large and active community.
• It is portable, meaning that it can be run on different types of computers without having to be rewritten.
• It is an interpreted language, which makes it easy to debug and modify.

यहां पायथन का उपयोग करने के कुछ लाभ दिए गए हैं:

• इसे सीखना और उपयोग करना आसान है।
• यह एक सामान्य-उद्देश्य वाली भाषा है, जिसका अर्थ है कि इसका उपयोग विभिन्न प्रकार के कार्यों के लिए किया जा सकता है।
• यह एक स्वतंत्र और मुक्त स्रोत भाषा है।
• इसका एक बड़ा और सक्रिय समुदाय है।
• यह पोर्टेबल है, जिसका अर्थ है कि इसे दोबारा लिखे बिना विभिन्न प्रकार के कंप्यूटरों पर चलाया जा सकता है।
• यह एक व्याख्या की गई भाषा है, जो डिबग और संशोधित करना आसान बनाती है।

In this course we will learn basics of Python from scratch and this course is specially designed for 'O' level students. This tutorial covers all the topics of 'O' level syllabus with PDF and MCQs.

( इस कोर्स में हम शुरुआत से पाइथन के बेसिक्स सीखेंगे और यह कोर्स विशेष रूप से 'ओ' लेवल के छात्रों के लिए बनाया गया है। यह ट्यूटोरियल PDF और MCQ के साथ 'ओ' स्तर के पाठ्यक्रम के सभी विषयों को शामिल करता है। )
