代碼中的語法錯誤，但不是在代碼行

Question

所以我試圖編程的東西，並有一些奇怪的事情，當試圖運行我的代碼我得到的第3行語法錯誤，但是當我只運行特定的代碼行一切正常。這怎麼可能？它是用python寫的（如果有的話）

p = float(input("What is the initial investment? ")) 
r = float(input("What is the nominal interest rate as a decimal? ") 
n = float(input("How many times a year will the interest be compounded?  ")) 
t = float(input("How many years will the interest be compounded")) 

a = p * (1 + r/n) ** (n*t) 

print "The final amount after %f years is %f" %t %a 

Answer 1

您在第2行丟失了一個右括號。正確，並且錯誤應該消失。

#Instead of 
r = float(input("What is the nominal interest rate as a decimal? ") 
#Do this 
r = float(input("What is the nominal interest rate as a decimal? ")) 
#This guy is missing - - - - - - - - - - - - - - - - - - - - - - - -^

Answer 2

試試這個，（在2nd線錯過brackets）。

r = float(input("What is the nominal interest rate as a decimal? "))
