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 […]
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
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
Modules are the pre-defined files that contain the python codes which depict the basic functionalities of class, methods, variables, etc. It consists of different functions, classes in a group of files inside a directory. Modules can also be termed as Libraries. These are basically the pre-defined methods that can be used to make the code
The following are the ways to compare two string in Python: By using == (equal to) operator By using != (not equal to) operator By using sorted() method By using is operator By using Comparison operators 1. Comparing two strings using == (equal to) operator Output: Enter the first String: AA Enter the second String:
Strings are basically sequence of characters. Python doesn’t support in-built string functions such as reverse() to reverse a string. The following are the ways to reverse a string in Python: By using a for loop By using a while loop By using a Slicing By using join() method By using Recursion By using List reverse()
Concatenation is a method of joining strings together to form a new string altogether. The following are the methods to perform String Concatenation in Python: By using + operator By using join() method By using % operator By using format() function By Literal String Interpolation By using StringIO from IO Module By using += concatenate
A substring is a sequence of characters within a String. When writing a Python program you may need to check whether a substring is present inside another string or not, there can be many reasons for that like searching and filtering data, input validation, etc. To check if a string contains a substring, we can
