Text files are the simplest way to store structured data and it’s quite easy to read and parse a text file in Python. Before CSV, before JSON, before databases, there were text files. They still show up everywhere, which means…
You are writing a Python program and need to output bracket characters in your output. A user-facing message might need square brackets. A debug statement might need curly braces. The print() function does not make this obvious because brackets also…
The python sorted function returns a new list containing all elements from any iterable arranged in ascending order. Unlike the sort() method that modifies lists in place, sorted() creates a fresh list while preserving your original data structure. This distinction…
The python map function applies a transformation to every element in an iterable without writing explicit loops. You pass a function and one or more iterables, and map returns an iterator containing transformed values. Understanding how python map processes data…
That code extracts email addresses from text using Python regex. The pattern looks cryptic at first, but each piece serves a specific purpose in matching the structure of an email address. Regular expressions give you a tiny language for describing…
The range() function generates a sequence of numbers that you can iterate over. That’s it. Three parameters, one simple job. You give it boundaries, and it gives you integers within those boundaries. Most Python developers use range() every single day…
That’s Python enumerate() in its most basic form. It takes any iterable and returns both the index and the value at each iteration. The syntax is enumerate(iterable, start=0), where start is optional and defaults to zero. Why enumerate exists in…
Testing and debugging are crucial when it comes to building a code and maintaining it. While they are used on a large scale in developing and making projects in the industry, we also use them daily on a small scale.…
In this article, we’ll perform DNS Lookups in Python using the ‘socket’ module and ‘socket.getaddrinfo()’ function for generating the domain information and converting it into an IP address while using the /etc/hosts files for storing the generated IPv4 and IPv6…
Suppose you are working with a load of text from a different language or even English that is obtained from different sources and may have many duplicate words in the sentences. You just need the summary of the text before…
