Poetry generator

步驟1：製作

它是什麼？

The poetry generator project creates random phrases that you can use in a poem, as a password or to start a story. It's nice to share especially poetic or funny phrases with your friends.  

這兩支影片為您示範了製作內容和編碼方法：

What will you learn?

You will learn about arrays, a special kind of variable. Arrays are a useful way of storing data in lists.

運作方式

• When you shake your BBC micro:bit, a random phrase is created that consists of an adjective, noun, verb, then adverb, for example, ‘beautiful bird eats swiftly’.
• You can either use your phrase to start a poem or alongside other phrases generated by this program to write an entire poem.
• The program uses four arrays called ‘adjectives’, ‘nouns’, ‘verbs’, and ‘adverbs’.
• Each array stores a list of words. Each item in an array is called an element. The elements are numbered with an index. For example, the array ‘noun’ includes three elements: element 0, bird; element 1, butterfly; and element 2, dragonfly. The indices are numbered from 0 because computers start counting at 0.
• When you shake your micro:bit, a random number between 0 and 2 is chosen for each array. The elements for those indices are shown on the micro:bit’s LED display.

18           'silently',
19           'skillfully']

21while True:
22    if accelerometer.was_gesture('shake'):
23        choice = random.randint(0, len(adjectives)-1)
24        display.scroll(adjectives[choice])        
25        choice = random.randint(0, len(nouns)-1)
26        display.scroll(nouns[choice])
27        choice = random.randint(0, len(verbs)-1)
28        display.scroll(verbs[choice])
29        choice = random.randint(0, len(adverbs)-1)
30        display.scroll(adverbs[choice]) 

步驟3：進階

• Add more adjectives, nouns, verbs, and adverbs to the program.
• Find a way to generate more lines for your poem using other inputs such as button A or button B.
• Can you write a program to generate a haiku?
