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 theinput()function to the variablename, such asname = 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 theendparameter controls what is printed at the end of the output, such asprint("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\ncharacter, which can be seen withprint(name, end="\n"). - To alter the output, the value of the
endparameter 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
\nindicates a new line, a key aspect of controlling output formatting.
