In your object initialisation code, you have the following: self.Grade = self.GetGrade() self.LenGrade = self.GetLenGrade() This means “set the value of the data member Grade to the value obtained by calling the method GetGrade” and the same for LenGrade. It should not be surprising that they’re called, it would be more surprising if they were … Read more
Alternative approach to achieve this by using reduce() function as: >>> operation_str=”3^2^4^1^0″ >>> reduce(lambda x, y: int(y)**int(x), operation_str.split(‘^’)[::-1]) 43046721 Explanation based on step by step operation: >>> operation_str.split(‘^’) [‘3’, ‘2’, ‘4’, ‘1’, ‘0’] # Converted str into list >>> operation_str.split(‘^’)[::-1] [‘0’, ‘1’, ‘4’, ‘2’, ‘3’] # Reversed list >>> reduce(lambda x, y: int(y)**int(x), operation_str.split(‘^’)[::-1]) 43046721 … Read more
