蟒蛇測試前做，而語法錯誤

Question

這是我由於某種原因，我一直得到的，而語法錯誤程序，請排序這幫助我

#Variables 
Destination = " " 
MilesDest = 0 
MPG = 0 
GallonCost = 0 
GallonsNeeded = 0 
GasCost = 0 
Syntel = " " 

#Below begins Do-While pre-test 
while Syntel != "No": 
    Syntel = str(input("would you like to run this program?(Yes/No)(Case-Sensitive) ")) 
    Destination = str(input("Enter the name of your destination: ")) 
    MilesDest = float(input("Enter the amount of miles between your starting point and your destination: ")) 
    MPG = float(input("Enter the current MPG your car gets: ")) 
    GallonCost = float(input("Enter the current cost for a gallon of gas: ")) 
    GallonsNeeded = MilesDest/MPG 
    GasCost = GallonCost*GallonsNeeded 
    print("The number of gallons it takes to get to ",Destination, " is ",GallonsNeeded) 
    print("The cost of the trip to ",Destination, " is $",GasCost) 
#Salutation 
print("Thank you for using my program, good bye")

應該是while Syntel != "No":。缺少:。

您還遺漏Syntel =行上的右括號))。

請注意，一旦您糾正該問題，程序將永遠運行。
