#print()<---在python 3裡print是一個函數 所以必須加上括號 與之前python版本print不同
#input()<---輸入，輸入進來的型態為str
#str()<---將()內轉換成字串
def ex1():
  yourname = input("Please input your English name:")
  for i in range(0,4):
      print(yourname[i]+" ASCII value is "+str(ord(yourname[i])))

#輸入4字元的字串
#ord()轉換()內字元所對應的ascii瑪
#chr()轉換()內數字所對應的字元<---須為int
def ex2():
  var = input("Please enter a four character string:")
  print("The string capitalized is ",end="")
  for i in range(0,4):
      print(chr(ord(var[i])-32),end="")
  print()
#mpg mile per gallon
#求每一加侖所跑的里程
#輸入miledorve、gallon
#miledorve/gallon=每加侖所跑的miles
def ex3():
  miledrove = float(input("Please enter the miles you drove:"))
  gallons = float(input("Please enter the gallons \
  of gas you put in the tank:"))
  print("You got",str(miledrove/gallons),"mpg on that tank of gas.")
  
#美元與外國幣值稅換
#以美國為主所以要查美國相對於各國的匯率
#rate此函式中代表匯率
#結果應該是 所要稅換的錢幣*匯率
def ex4():
  dollars = float(input("What is the amount of US \
  Dollars you wish to convert? "))
  rate = float(input("What is the current exchange \
  rate (1~US Dollar equals what in the Foreign Currency)? "))
  print("The amount in the Foreign Currency is $%.2f"%(dollars*rate))
#以list來做9*9乘法表
#必須清楚for迴圈內的動作，變數的變動
#了解如何存取list內的內容

  X=list(range(1,10))#[1,2...9]

#店員找錢
#使用while迴圈 應找的錢(change) dollars(各種錢幣) pay(應找的硬幣數)
#每一次迴圈 把當時所要找的錢除目前使用的硬幣 得到其商 就是這種硬幣要找的數量
#找完一次，必須要把找的錢與已給的錢(硬幣直*找的硬幣數量)相減
#迴圈直到要找的錢為0時，結束迴圈
