Why Variables Are Considered The Core Of A Python Programme

What are the other software domains where Python is Used in Significant?

Though, Python itself is a king of software languages, but one of the best things where it gets along with, is Big Data. Companies go gaga over an individual who knows both Python and a bit of Big Data. But, what makes them the best of friends? Data Science has now become one of the greatest platforms to use python as there is a need to integrate data analysis and web apps. With the powerful library that Python has, the machine learning algorithms get supported and in many huge aspects both the languages gets complimented.

Companies where Python Jobs are always in abundance

Though there is not a single industry where software language jobs are not in abundance, but there are a few companies where there is always a need of the developers, especially python aspirants. Some of the industry giants where Python Developers are always required are:

1. Adobe
2. Google
3. Spotify
4. Instagram
5. Apple
6. Microsoft
7. Facebook

to name a few

The list,though goes on and on but the companies listed above are considered as the dream ones for an aspirant.

Strings In Python

Python string is an ordered collection of characters which is used to represent and store the text-based information. Strings are stored as individual characters in a contiguous memory location. It can be accessed from both directions: forward and backward. Characters are nothing but symbols. Strings are immutable, which means that once a string is created, they cannot be changed. In this module, we will learn all about strings in Python so as to get started with strings.

Creating a String in Python

In Python, strings are created using either single quotes or double quotes. We can also use triple quotes, but usually triple quotes are used to create doc strings or multi-line strings.

Accessing Python String Characters

In Python, the characters of string can be individually accessed using a method called indexing. Characters can be accessed from both directions: forward and backward. Forward indexing starts form 0, 1, 2…. Whereas, backward indexing starts form?1,?2,?3…, where?1 is the last element in a string,?2 is the second last, and so on. We can only use the integer number type for indexing; otherwise, the Type Error will be raised.

Numbers In Python

In Python, the number data type is used to store numeric values. Numbers in Python are an immutable data type. Being an immutable data type means that if we change the value of an already allocated number data type, then that would result in a newly allocated object.

Categories of Number Data Type

The number data type is further categorized based on the type of numeric value that can be stored in it. If a variable in Python contains a numeric value, the data type of that variable will be under one of the categories of the number data type based on the type of value assigned to that variable.

The number data type is divided into the following five data types:

• Integer
• Long Integer
• Octal and Hexadecimal
• Floating-point Numbers
• Complex Numbers
