How to detect keyboard input in a Python script from the terminal?

The simplest way to detect keyboard input in a script from the terminal

There are a few different ways to detect keyboard input in a script from the terminal. The simplest way is to use the input() function. This function will pause the script and wait for the user to enter some text, which is then stored in a variable. For example, the following script will print whatever the user types into the terminal:

>>> text = input("Enter some text: ")
Enter some text: Hello world
>>> print(text)
Hello world

Another way to detect keyboard input is to use the raw_input() function. This function is similar to the input() function, but it does not evaluate the user's input as Python code. This can be useful if you want to read in data that contains special characters or if you want to process the input yourself. For example, the following script will read in a line of text from the terminal and then print it out:

>>> text = raw_input("Enter some text: ")
Enter some text: Hello world
>>> print(text)
Hello world

Finally, you can also use the sys.stdin.readline() function to read keyboard input. This function will read a line of text from the standard input stream, which is typically the terminal. For example, the following script will read a line of text from the terminal and then print it out:

>>> text = sys.stdin.readline()
Enter some text: Hello world
Hello world

Which of these methods you use will depend on your specific needs. If you simply want to read in a line of text from the terminal, then the input() function is the easiest to use. If you need to read in data that contains special characters or if you want to process the input yourself, then the raw_input() function is a better choice. And if you need to read keyboard input from a specific stream, then the sys.stdin.readline() function is the most flexible.
