Python: First even and odd number in a given list of numbers

Python List: Exercise - 137 with Solution

Write a Python program to find the first even and odd number in a given list of numbers.

Sample Solution:

Python Code:

def first_even_odd(nums):
    first_even = next((el for el in nums if el%2==0),-1)
    first_odd = next((el for el in nums if el%2!=0),-1)
    return first_even,first_odd

nums= [1,3,5,7,4,1,6,8]
print("Original list:")
print(nums)
print("\nFirst even and odd number of the said list of numbers:")
print(first_even_odd(nums))

Sample Output: 

Original list:
[1, 3, 5, 7, 4, 1, 6, 8]

First even and odd number of the said list of numbers:
(4, 1)

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
