以下是求解n以内所有完数的 Python 代码:
```python
def find_perfect_numbers(n):
perfect_numbers = []
for i in range(1, n + 1):
factors = []
for j in range(1, i):
if i % j == 0:
factors.append(j)
if sum(factors) == i:
perfect_numbers.append(i)
return perfect_numbers
n = int(input("请输入n的值:"))
perfect_numbers = find_perfect_numbers(n)
print("在", n, "以内的所有完数为:", perfect_numbers)
```
输出结果示例:
```python
请输入n的值:10000
在 10000 以内的所有完数为: [6, 28, 496, 8128]
```
将所有完数放在一个列表中并输出,可以在 `find_perfect_numbers` 函数中添加一行代码:
```python
def find_perfect_numbers(n):
perfect_numbers = []
for i in range(1, n + 1):
factors = []
for j in range(1, i):
if i % j == 0:
factors.append(j)
if sum(factors) == i:
perfect_numbers.append(i)
print("所有完数为:", perfect_numbers) # 添加这行代码
return perfect_numbers
n = int(input("请输入n的值:"))
perfect_numbers = find_perfect_numbers(n)
```
输出结果示例:
```python
请输入n的值:10000
所有完数为: [6, 28, 496, 8128]
在 10000 以内的所有完数为: [6, 28, 496, 8128]
```
