Learning Python gives the programmer a wide variety of career paths to choose from. Python is an open-source (free) programming language that is used in web programming, data science, artificial intelligence, and many scientific applications. Learning Python allows the programmer to focus on solving problems, rather than focusing on syntax. Its relative size and simplified syntax give it an edge over languages like Java and C++, yet the abundance of libraries gives it the power needed to accomplish great things.

Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data. Since everything is an object in Python programming, data types are actually classes and variables are instance (object) of these classes.

Decision making is anticipation of conditions occurring while execution of the program and specifying actions taken according to the conditions. Decision structures evaluate multiple expressions which produce TRUE or FALSE as outcome. You need to determine which action to take and which statements to execute if outcome is TRUE or FALSE otherwise

Control statements in python are used to control the order of execution of the program based on the values and logic. Python provides us with 3 types of Control Statements: Continue Break Pass

What is a List in Python? A list is just like an array, but its declaration occurs in other languages. The lists don’t always need to be homogenous. Thus, it becomes the most powerful tool in the case of the Python language. A single list may consist of various DataTypes, such as Strings, Integers, and also Objects. The Lists are always mutable. Thus, we can alter it even after we create it. What is a Dictionary in Python? A dictionary, on the other hand, refers to an unordered collection of the data values that we use for storing the data values, such as a map. Unlike the other DataTypes, which are capable of holding only a single value in the form of an element, a Dictionary is capable of holding the key:value pair. In a Dictionary, a colon separates all the key-value pairs from each other, while a comma separates all the keys from each other.

Python provides inbuilt functions for creating, writing, and reading files. There are two types of files that can be handled in python, normal text files and binary files (written in binary language, 0s, and 1s). Text files: In this type of file, Each line of text is terminated with a special character called EOL (End of Line), which is the new line character (‘\n’) in python by default. Binary files: In this type of file, there is no terminator for a line, and the data is stored after converting it into machine-understandable binary language

Python too supports file handling and allows users to handle files i.e., to read and write files, along with many other file handling options, to operate on files. The concept of file handling has stretched over various other languages, but the implementation is either complicated or lengthy, but like other concepts of Python, this concept here is also easy and short. Python treats files differently as text or binary and this is important. Each line of code includes a sequence of characters and they form a text file

What Is Object-Oriented Programming in Python? Object-oriented programming is a programming paradigm that provides a means of structuring programs so that properties and behaviors are bundled into individual objects.

Errors are the problems in a program due to which the program will stop the execution. On the other hand, exceptions are raised when some internal events occur which changes the normal flow of the program. Two types of Error occurs in python. Syntax errors Logical errors (Exceptions)

There are many graphical user interface (GUI) toolkits that you can use with the Python programming language. The big three are Tkinter, wxPython, and PyQt. Each of these toolkits will work with Windows, macOS, and Linux, with PyQt having the additional capability of working on mobile
