Python ─ Tip Calculator

Tip Calculator


※ 宣告值

meal = 44.50;          # 宣告一個值為44.50
tax = 0.0675;           # 宣告一個 6.75% 的值，要宣告為0.0675
tip = 0.15;               # 宣告一個 15% 的值， 要宣告為0.15
_________________________________________

※ 設一個變數 itself 且itself 等於meal，並套用到 meal =itself+itself*tax 

meal = 44.50
tax = 0.0675
tip = 0.15
itself=44.5;
meal =itself+itself*tax

---------------------------------------------------------
Result：47.50375
_________________________________________

※ 設一個變數 total ，算出meal+meal*tip  並印出來

# Assign the variable total on line 8!

meal = 44.50
tax = 0.0675
tip = 0.15

meal = meal + meal * tax  # 等於上題的meal =itself+itself*tax

total = meal+meal*tip      # 求出和

print("%.2f" % total)         # 印出小數點後兩位

---------------------------------------------------------
Result： 54.63
