PART I: Trivial Question with AI#

Q1_1: Converting Fahrenheit to Celsius temperature degree#

請你寫出轉換攝氏溫度為華氏溫度的Code。並輸出為以下型態例如：（攝氏tc溫度等於華氏tf溫度減32後乘以5/9）。請你寫出轉換華氏溫度為攝氏溫度的Code。

Sample output: 
    tc:  10 	tf:  50.0

tc = 10
# Your code should be here

Q1_2: 計算一元二次方程的解#

題目描述：已知一個一元二次方程 (ax^2 + bx + c = 0)，其中 (a = 1, b = -3, c = 2)，請寫一個 Python 程式計算它的兩個解。

解的公式（注意應該會有兩個答案）： $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

import math

# 已知 a, b, c
a = 1
b = -3
c = 2

# 在這裡寫程式碼計算解

# 在這裡輸出解

Q1_3: String as list#

在Python中，string字串也可以用list的方式來存取。如

word = "Pneumonoultramicroscopicsilicovolcanoconiosis" # 實際上存在的單字
print(word[3])

請用dictionary計算該字串中每個字元出現過幾次。

Output: 
    {'P': 1, 'n': 4, 'e': 1, 'u': 2, 'm': 2, 'o': 9, 'l': 3, 't': 1, 'r': 2, 'a': 2, 'i': 6, 'c': 6, 's': 4, 'p': 1, 'v': 1}

cdict = {}
word = "Pneumonoultramicroscopicsilicovolcanoconiosis"

# YOUR CODE SHOULD BE HERE

print(cdict)

{}

PART II: Accessing Taipei Bus real time data#

以下是台北市某線公車的即時資料。資料中主要分為兩大塊，包含該線公車的停靠站以及正在路上跑的公車（通常不只一台）及其位置。請觀察該資料並回答以下問題。

HINT: 這些題目其實都可以問AI把答案問出來，但要稍微思考一下，要怎麼印。

import requests
import json
url = "https://pda.5284.gov.taipei/MQS/RouteDyna?routeid=11763&nocache=1633009377839"
response = requests.get(url)
route = json.loads(response.text)
print(type(route))

route

PART III: Reviewing with AI#

你只需要把以下問題拿去AI，把AI告訴你的結果，貼在下方的markdown cell即可。但請你借此練習一下使用markdown，把AI告訴你的結果整理好。

Q3_1: 請用公車的資料說明，何謂List？#

Q3_2: 請用公車的資料說明，何謂Dictionary？#

Q3_3: 請用公車的資料說明，for-loop的機制與功能？#

Q3_4: 公車的資料除了以上題目外，你還可以用來做什麼？#

HINT 1：不單只考慮一條路線？
HINT 2：可否結合視覺化的功能？
HINT 3：是否可以結合其他資料？
HINT 4：可否動態呈現？
HINT 5：還可以做出什麼應用？
