def fixedPoint(f, epsilon):? ? """? ? f: a function of one argument that returns a float? ? epsilon: a small float??? ? returns the best guess when that guess is less than epsilon?? ? away from f(guess) or after 100 trials, whichever comes first.? ? """? ? guess = 1.0? ? for i in range(100):? ? ? ? if f(guess) - guess < epsilon:? ? ? ? ? ? return guess? ? ? ? else:? ? ? ? ? ? guess = f(guess)? ? return guess這個代碼有一行是有錯誤的 但是我有不知道錯誤在哪里希望能有大佬幫忙講解一下f是一個函數返回一個浮點數epsilon是一個浮點數
