1. Permutation with itertools:

In this program, we import the built-in module called itertools. With itertools, you can find all the permutations of the given string. In itertools there are numerous methods, you can try a combination and other methods.

2. One-Line Condition Expression:

This conditional expression was added to Python 2.5 version. This can be used with A if condition else B syntax. First, the condition is evaluated and returns based on the boolean value of the condition. If it is true it returns A or else if it is false it returns B.

3. Reverse a string:

In this program, we use an extended slice to reverse the…

In this article, five important functions are explained in detail with code. These functions are simple yet the most powerful function in Python. Python has many libraries and built-in functions. Understanding these functions and using them properly helps with efficient programming.

1. Lambda Function:

One of the most powerful functions in Python also known as the anonymous function. It is known as anonymous because we can instantiate and declare a function without a name. If you have a single operation to be executed, the lambda function is extremely useful instead of declaring a traditional function. …

Implementing string formatting helps with control over the console while printing. It reduces the junk code and makes it much easier to read the code. In this article, let us understand three commonly used string formatting methods.

C - style string formatting method:

If you have ever worked with c programming, then this should sound familiar. This uses a % operator to format the string in the program. Commonly used string formatting placeholders are:

  • %s - It acts as a place holder for string or other objects
  • %d - It acts as a placeholder for integers
  • %f - It acts as a placeholder for floating-point numbers

Extensive markup language supports the hierarchical representation of the data. Understanding parsing and modification of an XML file are important for web scraping. Searching, modification, and processing of the XML document are explained in this article.

For better understanding, let us consider an example XML file:

Parsing of the XML file:

To parse an XML file first import ElementTree package for parsing an XML file. ET is a commonly used alias for the ElementTree. Parsing is a process where the interface reads the XML documents. After reading the XML file, the interface can perform certain functions like searching, building, modifications.

Accessing each node’s text in the XML file:

While the XML…

The Internet, phones, camera, and social networks continue to thrive and become an essential part of our lives. Logically, you can find thousands of social media uses. Among them, I use Instagram as a diary to keep all my photos to ensure the fond memories are not lost.

I have two profiles, one is for actual socializing, and the other is for keeping my photos. My diary account has no followers, and its sole purpose is to keep my data safe, organized, and caption to represent that moment.

Haven’t you noticed losing some photos and data somehow in the long…

Data structures are used to store data more efficiently. In python, there are four kinds of iterable objects which are used for the collection of data. The four data structures in python are Lists, Tuples, Sets, Dictionary. These data structures are used from simple programs to complex programs. Proper understanding and usage of this data structure help run efficiently.
