Study Notes

User Input

The input() function pauses the program to await user input and returns that input as a value.
When using input("What's your name?"), the program will prompt the user for their name and allow them to type it in.

Variables

Variables act as storage containers for data or values within a program.
The assignment operator = assigns the output of the input() function to the variable name, such as name = input("What's your name?").
After assigning the input value to the variable, it can be referenced later, like print(name).

Function Parameters

Function parameters allow the specification of how the function behaves and how it processes arguments.
Modifying the print() function with the end parameter controls what is printed at the end of the output, such as print("Hello", end="") which outputs without starting a new line.

New Line Character

The default behavior of print() is to add a new line after each call by using the \n character, which can be seen with print(name, end="\n").
To alter the output, the value of the end parameter can be modified to include spaces or other characters.

Modifications and Predictions

Users are encouraged to predict the outcomes of code changes before executing them for better understanding.
For example, changing the code to print("Hello", end=" ") results in the output being on the same line with a space after "Hello".

Key Learnings

Utilization of input() enables gathering user feedback via keyboard input.
Values returned by functions need to be stored in variables to be used later in the program.
Parameters can be specified in functions to change their behavior, enhancing function usability.
The special character \n indicates a new line, a key aspect of controlling output formatting.
