3.2 Lesson Period 4 - Tuples Data Abstraction

Tuples - 3.2.5

Definition

A tuple is an ordered, immutable collection of elements.
Tuples are similar to lists, but unlike lists, they cannot be changed once defined.
Tuples are created using parentheses ().

Example of a Tuple

# Creating a tuple
coordinates = (10.5, 12.7)

# Accessing elements in a tuple by index
x = coordinates[0]  # First element (index 0)
y = coordinates[1]  # Second element (index 1)

# Output
print("Tuple Example:")
print(f"X coordinate: {x}")  # Output: X coordinate: 10.5
print(f"Y coordinate: {y}")  # Output: Y coordinate: 12.7



```python
# Tuples are often used in different scenarios, such as storing RGB color values, coordinates, or points in geometry.
# Tuples are immutable, meaning their contents can't be changed after creation.

colorTuple = (255, 0, 128)  # RGB color value (red, green, blue)
print("Color Tuple:", colorTuple)
print("-"*50)

# Tuple Length
print("Length of colorTuple:")
print(len(colorTuple))
print("-"*50)

# Tuple Unpacking
print("Unpacking the tuple:")  # Quickly assign each value to a variable
red, green, blue = colorTuple  # Assigns the RGB values to separate variables
print("Red:", red)
print("Green:", green)
print("Blue:", blue)
print("-"*50)

# Tuple Repetition
print("Repetition of colorTuple:")  # Repeats the tuple values 2 times
print(colorTuple * 2)
print("-"*50)

# Min, Max, Sum
print("Minimum value in colorTuple:")  # Finds the smallest value
print(min(colorTuple))
print("Maximum value:")
print(max(colorTuple))
print("Sum of RGB values:")
print(sum(colorTuple))
print("-"*50)
