When developing a command line application in Python, it is important to be able to display information to the user as well as accept input from them. This can be achieved using the print() function to display information and the input() function to accept input.
To display information to the user, you can use the print() function as follows:
name = "Roger"
print(name)
By using print(), you can output the value of a variable or any other desired information to the console.
To accept input from the user, you can use the input() function like this:
print('What is your age?')
age = input()
print('Your age is ' + age)
When using input(), the program will pause and wait for the user to type something and press the enter key. The input provided by the user will be stored in the variable age in this example.
It is also possible to process more complex input or accept input at program invocation time. This allows for greater flexibility in handling user input. However, these topics will be covered in more detail later on.
It is important to note that while this approach works well for command line applications, other types of applications may require a different method for accepting user input.
