我有这个清单：

['79.9', '79.9', '79.9', '79.9', '103.2', '103.2']

我想用这个字典中的相应值替换列表项：

ValueDict = {
    "243": "0",
    "219.70000000000002": "1",
    "196.4": "2",
    "173.1": "3",
    "149.79999999999998": "4",
    "126.5": "5",
    "103.2": "6",
    "79.9": "7",
    "56.59999999999999": "8",
    "33.3": "9",
    "10": "10",
}

所以结果将是这样的列表： [7, 7, 7, 7, 6, 6]

我怎样才能做到这一点？

c = [b.get(i, i)for i in a]
c
['7', '7', '7', '7', '6', '6']

这应该有效：

[int(ValueDict[x]) for x in list1]

[7, 7, 7, 7, 6, 6]

类似于下面的东西

lst = ['79.9', '79.9', '79.9', '79.9', '103.2', '103.2']
ValueDict = {
    "243": "0",
    "219.70000000000002": "1",
    "196.4": "2",
    "173.1": "3",
    "149.79999999999998": "4",
    "126.5": "5",
    "103.2": "6",
    "79.9": "7",
    "56.59999999999999": "8",
    "33.3": "9",
    "10": "10",
}
new_lst = [ValueDict.get(x,'-1') for x in lst]
print(new_lst)

你可以用list comprehension来做到这一点。

final_list = [ValueDict[value] for value in my_list]

用于enumerate向列表添加计数器，然后检查元素是否在字典中，并调用值

for i,j in enumerate(l):
    if j in ValueDict:
        l[i]=ValueDict[j]
print(l)

输出：

['7', '7', '7', '7', '6', '6']
