我想將 id 附加到滿足特定條件的串列中。
output = []
areac = [4, 4, 4, 4, 1, 6, 7,8,9,6, 10, 11]
arean = [1, 1, 1, 4, 5, 6, 7,8,9,10, 10, 10]
id = [1, 2, 3, 4, 5, 6, 7,8,9,10, 11, 12]
dist = [2, 2, 2, 4, 5, 6, 7.2,5,5,5, 8.5, 9.1]
for a,b,c,d in zip(areac,arean,id,dist):
if a >= 5 and b==b and d >= 3:
output.append(c)
print(comp)
else:
pass
The condition is the following:
- areacount has to be >= 5
- At least 3 ids with a distance of >= 3 with the same area_number
所以 id 輸出應該是[10,11,12]。我已經嘗試過使用 Counter 的不同嘗試，但沒有成功。謝謝你的幫助！

干得好：
我將串列名稱更改為更具描述性的名稱。
output = []
area_counts = [4, 4, 4, 4, 1, 6, 7, 8, 9, 6, 10, 11]
area_numbers = [1, 1, 1, 4, 5, 6, 7, 8, 9, 10, 10, 10]
ids = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
distances = [2, 2, 2, 4, 5, 6, 7.2, 5, 5, 5, 8.5, 9.1]
temp_numbers, temp_ids = [], []
for count, number, id, distance in zip(counts, numbers, ids, distances):
if count >= 5 and distance >= 3:
temp_numbers.append(number)
temp_ids.append(id)
for (number, id) in zip(temp_numbers, temp_ids):
if temp_numbers.count(number) == 3:
output.append(id)
output將會：
[10, 11, 12]
