Question

水果包含列表-苹果，香蕉，橙和颜色包含列表-红色，黑色，橙色

因此，当我从单元格“ G1” 的下拉列表中选择水果和颜色时，然后“ Offset（0，-1）” 表示“ F1” 向我显示合并输出列表--（苹果，香蕉，橙色，红色，黑色，橙色）。因此，单元格“ F1” 中的列表包含重复值 Orange ，并打印两次。它应仅从选定的项目中选择唯一的项目，然后删除重复的项目，并应在单元格 F1 中以-（苹果，香蕉，橙色，红色，黑色）打印。

Answer 1

此代码是否适合从输出数组中删除重复项并为我提供唯一值。

f = [ 1, 3, 2, 3, 7, 5, 2]
for i in range(0, len(f-1)):
    for j in range(0, len(f-2)):
        ...

删除重复项并创建唯一列表
