  • In Python, the term prepend is a shortcut for the term pre-append. You might have used the append() function to add as many values to the end of a data structure as feasible. On the other hand, the prepend term is used to put values at the beginning of any data structure. As a result, we’ll explore various techniques for performing prepend on a list data structure.

  • There are various ways to convey a program’s output. Data is printed in a human-readable format, saved to a file for later use, or sent in any other format you specify. Users frequently desire more control over output formatting than just printing space-separated values. There are various options for output formatting.

  • Deque, or Double Ended Queue, is a queue in which pieces can be added and removed from the front or back. As a result, it does not adhere to the FIFO principle (First In, First Out).

  • Exceptions in Python programs can occur for various causes, and if they aren’t handled properly, they can cause the program to crash, resulting in data loss or, worse, data corruption. As a Python programmer, you must consider various exception scenarios and incorporate error management into your code.

  • In Python, the new line character indicates a line’s end and a new one’s start. If you wish to print output to the console and work with files, you’ll need to know how to use it.

  • In Python, a dictionary represents an unordered collection of data values that can be used to store data values in the same way a map can. The dictionary has a key-value pair, unlike other data types with a single value as an element. The key must be unique and unchanging, according to Dictionary. It means that a Python Tuple, unlike a Python List, can be used as a key.

  • Let’s face it: There are many different ways to use Python in your coding projects. And that’s not going away anytime soon. As developers increasingly adopt Python, we see more and more opportunities to incorporate it into our coding projects. How do you make sure you’re using it optimally?

  • The factorial of a positive number is computed using Python’s Numpy.math.factorial() method. But first, let’s define the term “factorial.” The numbers’ factorial o is the product of all positive non-zero numbers that are less than or equal. The general formula for computing the factorial of a number ‘n’ is as follows.

  • The abs() function in Python returns a number’s absolute value. The gap between an integer and zero is its absolute value. Any negative number becomes positive, whereas positive ones remain unchanged. For instance, abs(-9) returns 9, whereas abs(2) returns 2.

  • Before reading a file, you should familiarize yourself with the world of files. You want to know what a computer software sees when dealing with files. It makes it easy for you to comprehend and construct file-reading logic.

  • The replace() method is responsible for substituting one phrase for another. If nothing else is supplied, all occurrences of the specified phrase are substituted. replace() is a Python built-in function that returns a string copy with all occurrences of a substring replaced with another substring.
