In this article, we will learn how to iterate over the tuples in Dictionary in python. Methods Used The following are the various methods used to accomplish this task − Using Indexing Using dictionary.values() Method Using dictionary.items() Method Tuples are an immutable, unordered data type used to store collections in Python. Lists and tuples are similar in many ways, but a list has a variable length and is mutable in comparison to a tuple which has a fixed length and is immutable. Method 1: Using Indexing len() function − The number of items in an object is returned ... Read More

In this article, we will learn a python program to get the file name from the file Path. Methods Used The following are the various methods to accomplish this task − Using the OS module functions Using Pathlib Module Using Regular expressions(regex module) Method 1: Using the OS Module Functions Get the File Name From the File Path using the split() Function The split() function splits a string into a list. We can define the separator; the default separator is any whitespace. Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − ... Read More

In this article, we will learn how to get a negation of a Boolean in Python. In Python, the Boolean datatype is the built-in data type. It denotes the True or False values. For example, 520 is False. In this article, we will print the negation of a Boolean variable. The following are the various methods to accomplish this task − Using the “~” operator Using “not” Operator Using Operator Module Using Minus the value from ‘1’ Using bitwise_not(), logical_not() of Numpy Module Method 1: Using the “~” operator The negation of the operand can be returned using ...

In this article, we will learn how to generate IP addresses from the CIDR address. Methods Used The following are the various methods to accomplish this task − Generating IPv4 Network addresses Generating IPv6 Network addresses Accessing IP addresses of the CIDR address Method 1: IPv4Network Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − Use the import keyword to Import the ipaddress module. Use the ip_network() function(returns the type of network of the address ) of ipaddress module to get the IP addresses from an input CIDR address(IPv4Network) Use the ... Read More

In this article, we will learn a python program to find the profit or loss when the cost price CP of N items is equal to the selling price SP of M items. Assume we have taken N, and M values which represent the cost price of N items are equal to the selling price of M items. We will now calculate the profit or loss percentage. Formula profit/loss = ( (Cost Price) - (Selling Price) ) / (Selling Price) * 100 What is the Selling Price(SP)? The price a consumer pays to purchase a product or a commodity ... Read More

In this article, we will learn how to determine last Friday’s Date using Python. Methods Used The following are the various methods to accomplish this task − Using datetime module Using dateutil package Method 1: Using Datetime Module Algorithm (Steps) Following are the Algorithm/steps to be followed to perform the desired task. − Use the import keyword to import the datetime, timedelta from datetime module. Create a variable to store the list of all the days in a week(weekdays). Create a function getPreviousByDay() to return the last weekday of the input day by accepting the input day, ... Read More

In this article, we will learn how to detect whether a Python variable is a function. Sometimes, it is essential to figure out whether or not a Python variable is a function. When the code is a thousand lines long and you are not the creator of the code, this may appear to be of little value, and you may find yourself questioning if a variable is a function or not. Methods Used The following are the methods to check whether a python variable is a function − Using the built-in callable() function Using the isfunction() of the ... Read More

In this article, we will learn how to create a dictionary of sets in Python. Methods Used The following are the various methods used to accomplish this task − Using the Naive Method Using defaultdict() Method Using setdefault() Method Method 1: Using the Naive Method In this method, we create a dictionary of sets by passing sets as values to the keys. Syntax { ‘Key’: Set 1, ‘Key’:Set 2, ………….., ’Key’: Set n} Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − Create a variable to store the dictionary containing ...

In this article, we will learn how to capture SIGINT in Python and what has to be done after capturing it. When the signal module receives signals, it does a certain action. Besides that, it can capture the user's interruption through the keyboard using SIGINT. Modules Needed Signal Module The term "signal" refers to the process by which a program can receive information from the operating system. Additionally, the signals are sent to the program when the operating system detects specific events. By executing the following command at the terminal, the signal module can be installed − pip install signal ... Read More
