Here this example introduces how to get perfect numbers in the range of 1-1000 using Python.

### Source Code

```
#! /usr/bin/env python3
# -*- coding: utf-8 -*-
def Pnum(a):
b = []
for i in range(1,a):
if a%i==0 and i!=a:
b.append(i)
if sum1(b)==a:
c = []
c.append(a)
print(c)
def sum1(x):
s = 0
for i in range(0,len(x)):
s =s + int(x[i])
return s
print('Perfects numbers in the range of 1-1000:')
for i in range(1,1001):
Pnum(i)
```

Output:

```
Perfects numbers in the range of 1-1001:
[6]
[28]
[496]
```
