Working with Lists

Use these examples to see how lists and list utilities work in TinyPanda.

Get First and Last Item​

A simple program to grab the first and last names from a list.

bamboo names = ["panda", "tinypanda", "aprim"];

echoln(first(names));
echoln(last(names));

// Output:
// panda
// aprim

Adding and Removing Items​

This program adds "water" to the list, then removes it.

bamboo myList = ["bamboo"];

// Add "water" to list
append(myList, "water");
echoln(join(myList, ", "));

// Remove "water"  from the list
drop(myList);
echoln(join(myList, ", "));

// Output:
// bamboo, water
// bamboo

Check if Item Exists​

A quick check to see if "bamboo" is inside our list.

bamboo inventory = ["bamboo", "water"];

iff (contains(inventory, "bamboo")) {
    echoln("We have bamboo!");
} otherwise {
    echoln("No bamboo found.");
}

// Output:
// We have bamboo!

Calculate Average of List Elements​

This program takes a list of numbers, loops through them to calculate the sum, and divides by the list length to find the average.

bamboo marks = [85, 90, 78, 92, 88];
bamboo sum = 0;
bamboo i = 0;

// Loop through the list and add each number to the sum
loop (i < len(marks)) {
    sum = sum + marks[i];
    i++;
}

// Calculate the average
bamboo average = sum / len(marks);

echoln("Numbers: " + join(marks, ", "));
echoln("Sum = " + str(sum));
echoln("Average = " + str(average));

// Output:
// Numbers: 85, 90, 78, 92, 88
// Sum = 433
// Average = 86
