用迭代更改参数值

我有一个Excel文件，我需要从中获取一些数据。 当我使用常规整数，一切正常，但现在我很困难 – 我怎么能改变行值？ 这就是我现在所拥有的

dict_keys = ['Id', 'First name', 'Age', 'Condition Name', 'BiRad', 'Relevant Modality'] dict_values = [p_id, person_name, p_age, name, br, r] if f == 'Mass': #concatvals accepts (row, col, width, start, stop) shape = concatvals(row, 14, 5, 14, 19) #if row = 0 margin = concatvals(row, 14, 5, 14, 19) #here row should be 1 density = concatvals(row, 14, 5, 14, 19) # and here 2 - how to achieve that? dict_keys += ['Relevant Finding','Shape', 'Margin', 'Density'] dict_values += [f, shape, margin, density] 

这就是我所尝试的：

 if f == 'Mass': params = [shape, margin, density] loc = (row, 14, 5, 14, 19) for param in params: params[i] = concatvals(loc) loc[0] +=1 

但没有成功走得更远。 有什么build议么？ 谢谢！

Answer 1

使row成为循环参数，并将计算的值保存到数组中：

 dict_keys = ['Id', 'First name', 'Age', 'Condition Name', 'BiRad', 'Relevant Modality'] dict_values = [p_id, person_name, p_age, name, br, r] #concatvals accepts (row, col, width, start, stop) vals = [] for row in range(3): vals += concatvals(row, 14, 5, 14, 19) dict_keys += ['Relevant Finding','Shape', 'Margin', 'Density'] dict_values += [f] dict_values += vals 

Answer 2

它有点混乱你使用dict__的东西是不是一个字典，但一个列表…如果我明白你想要什么，我会到达这个：

 params = {'Mass': ['shape', 'margin', 'density'], 'Next': ['some', 'other', 'list']} if f == 'Mass': loc = (row, 14, 5, 14, 19) result = [f] for param in params[f]: result.append(concatvals(loc)) loc[0] +=1 dict_keys += ['Relevant Finding','Shape', 'Margin', 'Density'] dict_values += result elif f == 'Next': ... etc ...
