# Python Math: Find out, if the given number is abundant

## Python Math: Exercise-13 with Solution

Write a Python program to find out, if the given number is abundant.
Note: In number theory, an abundant number or excessive number is a number for which the sum of its proper divisors is greater than the number itself. The integer 12 is the first abundant number. Its proper divisors are 1, 2, 3, 4 and 6 for a total of 16.

Sample Solution:-

Python Code:

``````def is_abundant(n):
fctr_sum = sum([fctr for fctr in range(1, n) if n % fctr == 0])
return fctr_sum > n
print(is_abundant(12))
print(is_abundant(13))
```
```

Sample Output:

```True
False
```

## Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

```str="+++Welcome python+++"
str.strip()

print(str)```

Output:

`+++Welcome python+++`
