You can use the input() function to get input from the user. The input function takes a single argument, which is the prompt message displayed to the user. e.g name = input("Please enter your name: ") x=input("Enter first number: "); y=input("Enter second number: "); z=x+y; print(z); #2 input function -- In Python, the input() function is used to accept user input from the command line or console. name=input("Enter your name:"); print(name); -- In this example, the input() function prompts the user to enter their name. Whatever the user types in response is stored in the name variable. -- Note that the input() function always returns a string, so if we want to use the user's input as a number, we'll need to convert it using the appropriate type-casting function (e.g., int() for integers or float() for floating-point numbers). #3 Types of input data -- The input() function always returns a string, regardless of what the user enters. we may need to convert the input to a different data type if you want to perform calculations or other operations on it. e.g x=input("Enter first number: "); a=int(x); the input entered by the user is converted to an integer using the int() function in this example. #4 when to use index value -- If you want to get a single character from the user, we can use the input() function and index the result. e.g ch=input('enter a character: '); print(ch[0]) ch=input('enter a character: ')[0]; print(ch); #5 eval function eval function -- The eval() function in Python is used to evaluate an expression entered by the user as a string. The eval() function returns the result of the expression as a value. e.g x=eval(input("Enter an expression: ")); typeOf = type(x); print(typeOf); #6 Passing values from command line -- sys module provides access to any command-line arguments via the sys.argv list. we can pass arguments to a Python script from the command line using the sys.argv list. The first argument in the list is always the name of the script itself. suppose we have a file named Mycode.py in file we have written code import sys # without this line you will get error x=sys.argv[1]; y=sys.argv[2]; z=x+y; print(z); in command line we have to run this file #python3 Mycode.py 9 5 0 1 2 Note: Mycode is count as 0th argument 9 is count as 1st argument 5 is count as 2nd argument Github :- https://github.com/navinreddy20/Python- Python for Beginners :- http://bit.ly/3JOLQhl Editing Monitors : https://amzn.to/2RfKWgL https://amzn.to/2Q665JW https://amzn.to/2OUP21a.
