Before we start Python programming, we need to have an interpreter to interpret and run our programs. There are certain online interpreters like https://ide.geeksforgeeks.org/that can be used to run Python programs without installing an interpreter. Windows: There are many interpreters available freely to run Python scripts like IDLE (Integrated De...
Just type in the following code after you start the interpreter. Output: Let’s analyze the script line by line. Line 1: [# Script Begins] In Python, comments begin with a #. This statement is ignored by the interpreter and serves as documentation for our code. Line 2: [print(“GeeksQuiz”)] To print something on the console, print() function is used....

- Key features of Python. Pythonhas many reasons for being popular and in demand. A few of the reasons are mentioned below. Emphasis on code readability, shorter codes, ease of writing.
- Fundamentals of Python. Python Indentation. Python uses indentation to highlight the blocks of code. Whitespace is used for indentation in Python. All statements with the same distance to the right belong to the same block of code.
- Basics of Input/Output. Taking input from user – Python provides us with two inbuilt functions to read the input from the keyboard. raw_input(): This function works in older version (like Python 2.x).
- Data Types. Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data.
- First Byte of Python. Installation of Python. Your first program in Python. Using Python to perform mathematical Computation. Programming Style and documentation.
- Reading User’s Mind. Variables and values. Reading input from the user. Multiple Assignment. Simultaneous assignment.
- Numbers can be Operated. Numbers. Arithmetic Operators. Real-life application of Operators.
- Code is Choosy If… Why Selection statements? if statement explanation with flow chart. Comparison operators. Boolean type. if-else statement with flow chart.
- Comments in Python. Comments in Python are the lines in the code that are ignored by the interpreter during the execution of the program. Also, Comments enhance the readability of the code and help the programmers to understand the code very carefully.
- Keywords in Python. Keywords in Python are reserved words that can not be used as a variable name, function name, or any other identifier. Keywords. and. False.
- Python Variable. Python Variable is containers that store values. Python is not “statically typed”. An Example of a Variable in Python is a representational name that serves as a pointer to an object.
- Python Data Types. Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data.
1 day ago · To concatenate two lists index-wise, you need to iterate through both lists simultaneously and combine their corresponding elements. This can be achieved using a loop or comprehensions, and the zip function is particularly handy for this purpose. In Python, there are several ways to concatenate two list based on their index.
