python - 两个列表之间的减法差异

Question

我有以下查询集：

Iva_total= {'Iva a debito': [0, 0, 0, 0, 44.0, 0, 0, 0, 0, 0, 0, 0]}

Ricavi_total= {'Ricavi': [0, 0, 0, 0, 200.0, 0, 0, 0, 0, 0, 0, 0]}

我想做两个 list() 之间的区别Ricavi_total并Iva_total获得以下结果：

Difference = {'Difference': [0, 0, 0, 0, 156.0, 0, 0, 0, 0, 0, 0, 0]}

编辑

我的查询集由以下代码给出：

Ricavi_total={'Ricavi Lordi': [sum(t) for t in zip(*ricavi.values())],}
Iva_total={'Ricavi Lordi': [sum(t) for t in zip(*iva.values())],}

Answer 1

我们将使用zip()以减去列表，如：

list1 = Iva_total.get('Iva a debito')
list2 = Ricavi_total.get('Ricavi')

list_diff = [num2-num1 for (num1, num2) in zip(list1, list2)]

Difference = {}
Difference['Difference'] = list_diff

print(Difference)          # You will get what you want
