What Are 1-bit and 2-bit Characters? In computers, everything is stored in the form of bits, i.e., the smallest pieces of data that can be either 0 or 1. Now, when we talk about 1-bit or 2-bit characters, we mean how many of these bits are used to make a single character (like a letter or symbol). A 1-bit character is just a single 0. It counts as one character by itself. A 2-bit character is made of two bits and can be either 10 or 11. If we are given a list of bits (containing only 0s ... Read More
In Python, functions usually have a fixed number of arguments. However, there are situations where we may want to pass a variable number of arguments. In such cases, Python provides two special constructs: *args and **kwargs. *args allows a function to accept any number of positional arguments. **kwargs allows a function to accept any number of keyword arguments. We will discuss both of these concepts deeply in this article. What is "*args" in Python? In Python, *args allows a function to accept any number of positional arguments. These arguments are collected into a tuple inside the function, allowing ... Read More
What Is a 1/4 Mile Calculator? A 1/4 mile calculator helps to estimate how long it will take for a vehicle to cover a quarter-mile (about 400 meters) based on speed. This is a common way to measure a car's acceleration and performance in drag racing. To make this estimation, we will use the following basic formula: ET = (weight / horsepower) ** (1/3) * 5.825 In this formula: ET stands for Estimated Time in seconds Weight is the car’s weight in pounds Horsepower is the engine power in HP Creating a 1/4 Mile Calculator Using PyQt5 ...

Python is one of the programming languages known for its simple syntax, readability. Whether working on development, data analysis, or automation, Python provides the tools to get the task done with less effort. But beyond the basics, Python has some hacks that make the code not only shorter but also more efficient. These are not bugs or workarounds, but the smart ways of using the Python built-in features and functions to solve tasks in a faster manner. In this article, we are going to learn about the amazing hacks of Python. Performing a Swap Without a ... Read More
Census data is the source of information collected by the government to understand the population and its characteristics. It consists of details such as age, gender, education, and housing. This helps the government in understanding the current scenario as well as planning for the future. In this article, we are going to learn how to analyze the census data in Python. Python, with its libraries like pandas, numpy, and matplotlib, is widely used for analyzing census data. Analyzing Census Data Here, we are going to use the sample data that consists of the census data stored in ... Read More
The Telecom Regulatory Authority of India (TRAI) publishes the data regarding mobile internet speeds for various telecom operations across India. It is useful for users and telecom companies to evaluate and compare the performance of different service providers. In this article, we are going to use pandas in Python to analyze the TRAI mobile data speed reports. Let's assume we have downloaded the CSV file named demo.csv with the following structure to use in the examples. demo.csv file ... Read More
Earthquakes are natural phenomena that can have effects on human life and infrastructure. With the availability of geospatial and seismic datasets, scientists and researchers can analyze and visualize the earthquake data to identify the patterns, trends, and risk zones. Python, along with libraries like Matplotlib, Pandas, and NumPy, provides the tools to process and visualize the data. In this article, we are going to analyse and visualize earthquake data in Python with Matplotlib. Analyzing and visualizing Earthquake For the examples in this article, we use the dataset named "demo_1.csv" that contains information about the earthquakes. The data ... Read More
An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, using all the original letters exactly once. For example, thing and night are anagrams of each other. In this article, we are going to learn how to check an anagram in a Python program using collections.Counter() method. This method counts the number of occurrences of each element in a collection (like characters in a string), helping us to compare two words for identical character counts. For example, Scenario Input: str1= "listen", str2= "silent" Output: True Two strings are said ... Read More
The given task is to perform an alternate summation on a Python List. For example, adding the elements at even indices (0, 2, 4) or odd indices (1, 3, 5), depending on the requirement. This means we need to add every other element from the given list. Let us see an input scenario - Scenario Input: [11, 22, 33, 44, 55] Output: 99 Explanation: Here, we are going to add the elements at the even indices by using the slicing [::2]. Alternate Element Summation Using sum() Function The alternate element summation in a list (Python) can ... Read More
Slicing is used to extract a portion of a sequence (such as a list, a tuple, string) or other iterable objects. Python provides a flexible way to perform slicing using the following syntax. list[start:stop:step] Alternate Range Slicing The alternate range slicing is used to retrieve the elements from a list by skipping the elements at a fixed interval, using the step parameter. For example, if we want every second element from a list, we set step=2. Let’s observe some examples to understand how alternate range slicing works. Example 1 Consider the following ... Read More
