Python Logging module is used to implement a flexible event-driven logging system, which serves as a convenient way of storing log events or messages for an application. Python Logging Module – Loggers The Logger object is the object of this module which we can manipulate to do all our required logging. To instantiate a Logger […]
A Collection is used to represent a set of similar data items as a single unit that is used to group and manage related objects. They contain data structures that are used to manipulate and store data efficiently. Python collections module provides a lot of data structures to implement different types of collections. The following
Substring is a portion of the string that can be extracted and represented as a new string. In this tutorial, we will learn how to work with Substrings in Python. 1. Creating Python String Substring Substring can be created using either of the following methods: Slicing split() method Output: 2. Check for the presence of
The regular expression in Python are used to match a pattern with a string. Formally, a regular expression is a sequence of characters that define a search pattern. Python regular expressions are a powerful way to match text patterns. The module re, short for the regular expression, is the Python module that provides us all
A comparison operator identifies the relationship between the operands and results into True or False. One such basic yet important operator is not equal operator in Python. It returns True if the values on either side of the operator are unequal i.e. it returns True when two variables of same type have different values, else
Modules are basically pre-defined functions that help to reduce the redundancy to the code and add built-in functionalities to it. Python os Module allows us to interact and use the Operating System functionality efficiently. The os module allows us to gain access to the Operating System information. Thus, this module contains functions that serve as
Python sys module deals with the system and environment-specific variables and parameters. We can use it to read the PATH variable and the list of command-line parameters passed to the Python script. Import sys Module in Python Before using any module, it needs to be imported. Syntax: import module_name Example: import sys Python sys.modules This
We often come across a situation where we would need to store or transfer objects. The pickle module in Python is one such library that serves the purpose of storing Python objects as a serialized byte sequence into files for retrieval at a later time. Let us look into what it exactly does in this
The @staticmethod decorator Python @staticmethod decorator is used to label a class method as a static method, which means that it can be called without instantiating the class first. It simply defines a normal function that is logically contained in the class for readability purposes. Here, we do not need to pass the class instance
Operators are basically used to perform operations on the data to be manipulated. There are various kinds of operators i.e. Logical Operators, Bitwise Operators, Arithmetic Operators, etc. There are two kinds of AND Operators in Python: Logical AND Operator Bitwise AND Operator Logical AND Operator Logical AND operator work with boolean values and results into
