How to write Python regular expression to match with file extension?
Using Python, we can easily search for specific types of files from a mixed list of file names using regular expressions. For this, we need to import Python's built-in module called re using the import keyword. The Regular expression or Regex is a special sequence of characters like \, *, ^, etc, which are used to search for a pattern in a string or a set of strings. It can detect the presence or absence of characters by matching them with a particular pattern and can also split a string into one or more substrings. Importing the Regex ...
Read MoreWhat is __init__.py in Python?
In Python, __init__.py is a special file that makes a directory a Python package. When Python encounters a directory during import, it looks for the __init__.py file to determine how to initialize the package and what code should be executed. The __init__.py file serves two main purposes: It makes the directory a Python package so the interpreter can find modules inside It can contain package initialization code, such as importing submodules, defining variables, or executing setup code Package Structure with __init__.py Here's a typical package structure ? mypackage/ ...
Read MoreWhat is difference between raw_input() and input() functions in Python?
When working with user input in Python, developers often encounter two functions: input() and raw_input(). Understanding their differences is crucial for writing compatible code across Python versions. Python input() Function The input() function reads input from the user and returns it as a string. However, its behavior differs significantly between Python 2.x and Python 3.x versions. Python 3.x input() Behavior In Python 3.x, input() always returns a string, regardless of what the user enters ? num_1 = input("Enter value of num_1: ") num_2 = input("Enter value of num_2: ") print("Values are", num_1, num_2) print("Type ...
Read MoreAccumulator battery in Python
Problem Statement Consider a mobile phone, which is in "eco mode". This mode activates once your battery level reaches 20 percent. In this eco mode, the battery drains two times slower than in normal mode. This means that, in normal mode, if the time consumed by the battery is 1% per minute, then the time taken in eco mode is 1% per 30 seconds (1/2 minute). Scenario Now, when we leave our home, we have 100% of the battery. Then t minutes later we have p percent of battery left. We have to find how many minutes we have until ...
Read MoreHow to Create Acronyms from Words Using Python
The acronym is an abbreviated version of a sentence, which means it is the short form of the given sentence. It is formed from each word's first character in the given sentence. For example, CPU is an acronym of Central Processing Unit. In this article, we will learn how to create acronyms from words using Python. Scenario Input: my_str = "Automatic Teller Machine" Output: ATM Explanation: Here, the given string “Automatic Teller Machine”, we have created an acronym from it by considering first character of each word. Algorithm to Create Acronyms from Words The following are the steps ...
Read MorePython program for removing n-th character from a string?
The problem statement is to remove the nth character from the given string. Let's understand with an example. Consider my_string = "Tutorialspoint". The given value of n is 6; then we need to remove the 5th character from the string. Because the index value starts from zero. And it should result in "Tutorialspoint". Removing nth Character using a for Loop The for loop can be used to remove the n-th character from a string. In this approach, we iterate through each index of the string and print the characters. If the index value is equal to the given (n-1)th value, we ...
Read MoreHow to return an object from a function in Python?
In Python, we can return an object from a function, using the return keyword, just like any other variable. The statements after the return will not be executed. The return keyword cannot be used outside the function. If the function has a return statement without any expression, then the special value None is returned. In the following example, the function returned the sum of two numbers - def Sum(a, b): return a+b my_var1 = 23 my_var2 = 105 result_1 = Sum(my_var1, my_var2) # function call print(result_1) Following is an output of ...
Read MorePython program for Modular Exponentiation
What is Modular Exponentiation? To calculate Modular exponentiation, we need to raise a base to an exponent and then calculate the modulus of the result. This includes 3 integers: base, exponent, and modulo. Following is the syntax of the modular exponentiation in Python - (base**exponent) % modulo For instance, consider (2^5) % 5, which indicates 2 raised to the power of 5, which results in 32; When the modulo operation is performed, it returns the remainder, i.e., 32 % 5 is 3. Modular Exponentiation using Recursive Function A function that calls itself is known as a recursive function. Following is ...
Read MoreCreate Word Cloud using Python
A "word cloud" is a visual representation of text data, where the size of each word indicates its frequency or importance within the dataset. It helps us to identify the most common and important words in a text. It is typically used to describe/denote big data in a word. In this article, we will create a word cloud on the Python programming language, and the data is accessed from Wikipedia. Modules to create a Word Cloud in Python Following are the modules required to create a word cloud in Python : Install wordcloud Before installing the word cloud module, you have ...
Read MoreHow to convert HTML to PDF using Python
In general, we look at some external websites to convert our files to PDF format; instead, we can convert them using Python on our own. In this article, we will understand the steps to convert the HTML (Hyper Text Markup Language) to PDF using Python code. Steps to convert HTML to PDF Following are the steps to convert the HTML file to PDF using Python: Step 1: Installation Download the pdfkit library by running the following command in the command prompt: pip install pdfkit Step 2: Download wkhtmltopdf Following are the steps to download wkhtmltopdf: ...
