可以尝试以下代码实现:
```python
x = [20, 30, 40, 10, 8, 5]
# 添加元素到末尾
x.append(50)
print("After appending 50:", x)
# 在索引号3处插入元素
x.insert(3, 15)
print("After inserting 15 at index 3:", x)
# 输出索引号为3-7的元素
print("Elements at index 3-7:", x[3:8])
```
输出结果为:
```
After appending 50: [20, 30, 40, 10, 8, 5, 50]
After inserting 15 at index 3: [20, 30, 40, 15, 10, 8, 5, 50]
Elements at index 3-7: [15, 10, 8, 5, 50]
```

可以尝试以下代码实现:
```python
x = [20, 30, 40, 10, 8, 5]
# 添加元素到末尾
x.append(50)
print("After appending 50:", x)

x.insert(3, 15)
print("After inserting 15 at index 3:", x)
# 删除第一个元素
del x[0]
print("After deleting first element:", x)
```
输出结果为:
```
After appending 50: [20, 30, 40, 10, 8, 5, 50]
After inserting 15 at index 3: [20, 30, 40, 15, 10, 8, 5, 50]

已知列表x=【20.30.40.10.8.5】,编程实现以下功能Python
可以尝试以下代码实现:
```python
x = [20, 30, 40, 10, 8, 5]
# 找到列表中的最大值和最小值
max_value = max(x)
min_value = min(x)
print("Max value:", max_value)
print("Min value:", min_value)
# 对列表进行升序排序
x.sort()
print("Sorted list:", x)
# 对列表进行降序排序
x.sort(reverse=True)
print("Reverse sorted list:", x)
# 计算列表中所有元素的和
sum_value = sum(x)
print("Sum of all values:", sum_value)
# 计算列表中所有元素的平均值
avg_value = sum_value / len(x)
print("Average value:", avg_value)
```
输出结果为:
```
Max value: 40
Min value: 5
Sorted list: [5, 8, 10, 20, 30, 40]
Reverse sorted list: [40, 30, 20, 10, 8, 5]
Sum of all values: 113
Average value: 18.833333333333332
