Code-2 Variables and =

< CS101

This is a short section, to add the idea of variables to the code.


variable x as a box holding the value 7


code2-1

Variables work as a shorthand -- we = assign a value into a variable, and then use that variable on later lines to retrieve that value. In the simplest case, this just works to avoid repeating a value: we store the value once, and then can use it many times. All computer languages have some form of variable like this -- storing and retrieving values.

Code Example - The Curse

Change the code below so it produces the following output. Use a variable to store the string "Alice" in a variable on the first line like x = "Alice";, then use the variable x on the later lines. In this way, changing just the first line to use the value "Bob" or "Zoe" or whatever changes the output of the whole program.

Alice Alice Alice Alice
In high school I had a crush on Alice
Now the Alice curse is lifted


code2-2

x = "Alice";
print(x, x, x, x);
print("In high school I had a crush on", x);
print("Now the", x, "curse is lifted");
