Base size is the initial size of the calendar. In order to

Assigning multiple variables in one line in Python

A variable is a segment of memory with a unique name used to hold data that will later be processed. Although each programming language has a different mechanism for declaring variables, the name and the data that will be assigned to each variable are always the same. They are capable of storing values of data types. The assignment operator(=) assi

Create Constant Variable in Python using Pconst Library

Constant variable the name itself says that it is constant. We have to define a constant variable at the time of declaration. After that, we will not able to change the value of a constant variable. In some cases, constant variables are very useful. Creating constant variables, functions, objects is allowed in languages like c++, Java. But in pytho

What is the maximum possible value of an integer in Python ?

Consider below Python program. C/C++ Code # A Python program to demonstrate that we can store # large numbers in Python x = 10000000000000000000000000000000000000000000 x = x + 1 print (x) Output : 10000000000000000000000000000000000000000001 In Python, value of an integer is not restricted by the number of bits and can expand to the limit of the a

Functions that accept variable length key value pair as arguments

To pass a variable-length key-value pair as an argument to a function, Python provides a feature called **kwargs.kwargs stands for Keyword arguments. It proves to be an efficient solution when one wants to deal with named arguments in their function. Syntax: def functionName(**anything): statement(s) Note: adding '**' to any term makes it a kwargs

Python | Set 6 (Command Line and Variable Arguments)

Previous Python Articles (Set 1 | Set 2 | Set 3 | Set 4 | Set 5) This article is focused on command line arguments as well as variable arguments (args and kwargs) for the functions in python. Command Line Arguments Till now, we have taken input in python using raw_input() or input() [for integers]. There is another method that uses command line arg

__name__ (A Special variable) in Python

Since there is no main() function in Python, when the command to run a python program is given to the interpreter, the code that is at level 0 indentation is to be executed. However, before doing that, it will define a few special variables. __name__ is one such special variable. If the source file is executed as the main program, the interpreter s

Python | setting and retrieving values of Tkinter variable

Tkinter supports some variables which are used to manipulate the values of Tkinter widgets. These variables work like normal variables. set() and get() methods are used to set and retrieve the values of these variables. The values of these variables can be set using set() method or by using constructor of these variables.There are 4 tkinter variabl

Protected variable in Python

Prerequisites: Underscore ( _ ) in Python A Variable is anidentifierthat weassign to amemory locationwhich isused to hold values in a computer program. Variables are named locations of storage in the program. Based on access specification, variables can be public, protected and private in a class. Protected variables are those data members of

__file__ (A Special variable) in Python

A double underscore variable in Python is usually referred to as a dunder. A dunder variable is a variable that Python has defined so that it can use it in a "Special way". This Special way depends on the variable that is being used. Note: For more information, refer to Dunder or magic methods in Python The __file__ variable: __file__ is a variable

Full domain Hashing with variable Hash size in Python

A cryptographic hash function is a special class of hash function that has certain properties which make it suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash function) which is designed to also be a one-way function, that is, a function which is infeasible to in

Pad or fill a string by a variable in Python using f-string

f-string stands for formatted string. It had come up by Python Version 3.6 and rapidly used to do easy formatting on strings. F-string is a string literal having syntax starts with f and followed by {}. That placeholder used for holding variable, that will be changed upon the variable names and their values respectively. There are already strings f

PYTHONPATH Environment Variable in Python

Python's behavior is greatly influenced by its environment variables. One of those variables is PYTHONPATH. It is used to set the path for the user-defined modules so that it can be directly imported into a Python program. It is also responsible for handling the default search path for Python Modules. The PYTHONPATH variable holds a string with the

Unused local variable in Python

A variable defined inside a function block or a looping block loses its scope outside that block is called ad local variable to that block. A local variable cannot be accessed outside the block it is defined. Example: C/C++ Code # simple display function def func(num): # local variable a = num print("The number is :", str(a)) func(10) # g

Unused variable in for loop in Python

Prerequisite: Python For loops The for loop has a loop variable that controls the iteration. Not all the loops utilize the loop variable inside the process carried out in the loop. Example: C/C++ Code # i,j - loop variable # loop-1 print("Using the loop variable inside :") # used loop variable for i in range(0, 5): x = (i+1)*2 print(x, en

Python - Iterate through list without using the increment variable

Python Lists is much like flexible size arrays, declared in other languages like vector in C++, array list in Java, etc. Lists are heterogeneous, making it the most effective feature in Python. Lists are mutable, and hence can be modified even after they have been formed. The most common approach is to iterate through a list using the increment var

Python - Solve the Linear Equation of Multiple Variable

Prerequisite: Sympy.solve() In this article, we will discuss how to solve a linear equation having more than one variable. For example, suppose we have two variables in the equations. Equations are as follows: x+y =1 x-y =1 When we solve this equation we get x=1, y=0 as one of the solutions. In Python, we use Eq() method to create an equation from
