# Python: Compute the sum of digits of each number of a given list

## Python List: Exercise - 146 with Solution

Write a Python program to compute the sum of digits of each number in a given list.

Sample Solution:

Python Code:

``````def sum_of_digits(nums):
return sum(int(el) for n in nums for el in str(n) if el.isdigit())

nums = [10,2,56]
print("Original tuple: ")
print(nums)
print("Sum of digits of each number of the said list of integers:")
print(sum_of_digits(nums))

nums = [10,20,4,5,'b',70,'a']
print("\nOriginal tuple: ")
print(nums)
print("Sum of digits of each number of the said list of integers:")
print(sum_of_digits(nums))

nums = [10,20,-4,5,-70]
print("\nOriginal tuple: ")
print(nums)
print("Sum of digits of each number of the said list of integers:")
print(sum_of_digits(nums))
```
```

Sample Output:

```Original tuple:
[10, 2, 56]
Sum of digits of each number of the said list of integers:
14

Original tuple:
[10, 20, 4, 5, 'b', 70, 'a']
Sum of digits of each number of the said list of integers:
19

Original tuple:
[10, 20, -4, 5, -70]
Sum of digits of each number of the said list of integers:
19
```

## Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

```def tips_check_prop(fn, prop):
return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))
```

Output:

```True
```
