Text An Introduction to Python Python is a great general-purpose programming language that's becoming increasingly popular for data science. It aids the user in better comprehending the data by allowing them to see it. Not easy to convert code into other languages It is not easy to translate a Python program into other programming languages because Python does not have strong syntax. Large standard library: Python comes with a large standard library that has some handy codes and functions which we can use while writing code in Python. These type of text is known as comments. Interpreted Python is interpreted, interactive, and directly executed with pre-compiled code. Data : Data refers to the raw facts and figures. The input() function is used to accept values from the user at runtime. For instance, you can write (1 + 2) * 3, and the result would be 9 because of order of operations. The name of the variable must start with a letter or underscore (_) Single line comments: Single line comments are created by adding # at the beginning of the line .Syntax:#statementExample:print("Welcome to Python programme")#this program is used to display a line of textOutput: Welcome to Python programme2. In the previous article we have seen how to install Anaconda and jupyter notebook, creating and accessing the virtual environment, and writing a simple program with jupyter notebook. Comments are the statements which are incorporated in the code to give a better understanding of code statements to the user. 1 2 # An example of python code to output "I will become a python expert" print ("I will become a python expert") Heres a simple python code for displaying some text. In the next section of Unit 4 Introduction to Python AI Class 9 we will discuss the python if-else statements with python flow of controls. Large Standard Library and support GUI Programming (using MFC, Tkinter). Modula-3 is a language that preserves the power of a systems programming language. So lets begin! Question 7: Explain type function with example. Example: >>> 6+3 Output: 9. Python programs are also known as scripts. This function accepts and returns the text data by default. RD Sharma Class 10. Answer: Variables are containers used for storing data values. Code combat is one of the popular gaming portals to learn programming.
