爲什麼不Python的這項工作3.2.3

Question

Python 3.2.3 programming…Almost had it working

x = float(input("What is/was the cost of the meal?")) 
y = float(input("What is/was the sales tax?")) 
z = float(input("What percentage tip would you like to leave?")) 

print ("Original Food Charge: ${}" 
.format(x))) 
print ("Sales Tax: ${}" 
.format((y/100)*x))) 
print ("Tip: ${}" 
.format(x*(z/100))) 
print ("Total Charge For Food: ${}" 
.format(x+((y/100)*x)+((z/100)*x))) 

輸出錯誤：

線10條，在 語法錯誤：.format（X）））：行1015

有人報告說，這在他們早期版本的python（我認爲是v2.6）中有效。我正在使用後來的3.2.3版本，並且絞盡腦汁地想知道爲什麼這個版本無法使用。這對我有意義，請讓我注意。

Answer 1

.format(x*(z/100))後面有一個括號，屬於前面的print。

它應該是：

print ("Tip: ${}".format(x*(z/100))) 

UPDATE：不知道，如果你得到它的工作或沒有，這裏是你的固定不平衡括號後的完整代碼...

x = float(input("What is/was the cost of the meal?")) 
y = float(input("What is/was the sales tax?")) 
z = float(input("What percentage tip would you like to leave?")) 

print ("Original Food Charge: ${}" 
.format(x)) 
print ("Sales Tax: ${}" 
.format((y/100)*x)) 
print ("Tip: ${}" 
.format(x*(z/100))) 
print ("Total Charge For Food: ${}" 
.format(x+((y/100)*x)+((z/100)*x))) 

Answer 2

你錯過了第三次印刷後尾架：.format(x*(z/100)))

這裏是什麼似乎是一個工作版本之後，我固定支架：

x = float(input("What is/was the cost of the meal?")) 
y = float(input("What is/was the sales tax?")) 
z = float(input("What percentage tip would you like to leave?")) 

print("Original Food Charge: ${}".format(x)) 
print("Sales Tax: ${}".format((y/100)*x)) 
print("Tip: ${}".format(x*(z/100))) 
print("Total Charge For Food: ${}".format(x+((y/100)*x)+((z/100)*x))) 

也有不需要換行，如果線寬小於79

Answer 3

你錯過了前行密切括號：

.format(x*(z/100))
