In Python, there are two ways to provide input information to a program. One in which we directly assign input objects to object references/variables; and the other in which the program takes user input dynamically (during runtime). Python 2.x versions use raw_input() function to take user input dynamically; whereas, Python 3.x versions use input() function. The input() function only takes input values in the form of strings, by default. In this article, we will learn how to read the input as “Numbers” in Python 3.x using input() function. Reading Inputs as Numbers Python, like any other programming languages, accepts two ... Read More

Python is a high-level programming language that helps users to run a program and integrate systems more efficiently, as it executes a program in comparatively fewer lines of code. In Python programming language, a code can be executed in two ways - Interactive Mode Script Mode In this article, we will learn how to execute a Python program in script mode on Windows. However, the steps are almost the same for other operating systems.Python Script Mode Script mode in Python allows us to write Python code in files with the .py extension and run the entire program at ...

In Python programming language, a code can be executed in two ways - Interactive Mode Script Mode In this article, we will learn how to execute Python code in Interactive mode in Windows. However, the commands are almost the same in other operating systems as well. Interactive Mode Interactive mode in Python is a built-in feature that allows users to execute Python commands one line at a time. ... Read More

The command line is the place where executable commands are given to the operating system. In Python, command-line arguments allow users to pass information to a script when it's executed from the terminal.  A Python script can be executed by writing its name in front of the Python executable on the command line. Following is the example command which executes the Python file named sample.py - python sample.py If we need to pass arguments to a script, we can pass them at the time of execution, separating them by a space as shown below - python test.py Hello TutorialsPoint Python ...

In Python, both single quotes (') and double quotes (") are used to define string literals, and they function in the same way.  For example, if a string contains a single quote character, like in a contraction, i.e., it’s by using double quotes avoids the need for escape characters by making the code cleaner and easier to read. Similarly, single quotes can be useful when a string contains double quotation marks. Single Quotes in Python Single quotes are used to wrap small and short strings in Python, such as string literals or identifiers. We must remember that using single quotes ... Read More

A statement is a logical instruction in Python that the Python interpreter can read and execute. It could be an expression or an assignment statement in Python. Python's assignment statement is fundamental. It specifies how an expression generates and stores objects. In a simple assignment, we create new variables, assign values to them, and alter them. To maintain the value of the expression, this statement supplies an expression and a variable name as a label. Following is the syntax of using the statement in python − variable = expression Creating Multi-Line Statements in Python Statements in Python are often ... Read More

To run a Python file in a directory, we generally use the Python or python3 command. However, it only runs a single file at a time. But executing one file each on a shell script seems hectic. Therefore, we must come up with a way to execute all files present in a directory simultaneously. In this article, let's go through the different methods to run all the Python files in a directory at a time. Using subprocess Module Using exec() function Using shell scripts Using multiprocessing Using subprocess.run()  The subprocess ... Read More

In Python, determining the current directory of program execution is a common task, especially when working with file operations, configuration of files or dynamically accessing resources. The current directory refers to the location from which the script is being run, but not necessarily where the script file resides. Python provides two main ways to retrieve the current directory information, using the os module and the pathlib module. Significance of the Current Directory The current directory in Python is the folder from which our script is being executed. It’s important to find the current directory because all the relative file paths ... Read More

When programming in Python, proper indentation is essential as the language uses it to define the structure of the code such as loops, functions and conditionals. Even minor mistakes in indentation can lead to errors or unexpected behavior by making it critical to maintain consistency. Vim Editor Vim is a highly efficient text editor which offers flexible configuration options to automate indentation by ensuring that our code is properly formatted according to Python's standards. By adjusting Vim's settings we can configure it to handle indentation in Python files with ease. This includes converting tabs to spaces, setting the appropriate indentation ... Read More

Monitoring Python files for changes is essential in many development and automation scenarios such as triggering automatic reloads, running tests, or updating services when the source code is modified. This is particularly useful in web development, machine learning pipelines or custom tooling where real-time responsiveness to file updates is beneficial. One effective way to achieve this in Python is by using the watchdog library which is a simple and efficient tool that listens for file system events like creation, modification, and deletion. With watchdog library the developers can set up observers that watch specific directories and respond to the changes ... Read More
