Python: Join adjacent members of a given list

Python List: Exercise - 203 with Solution

Write a Python program to join adjacent members of a given list.

Sample Solution:

Python Code:

def test(lst):
    result = [x + y for x, y in zip(lst[::2],lst[1::2])]
    return result

nums = ['1','2','3','4','5','6','7','8']
print("Original list:")
print(nums)
print("\nJoin adjacent members of a given list:")
print(test(nums))

nums = ['1','2','3']
print("\nOriginal list:")
print(nums)
print("\nJoin adjacent members of a given list:")
print(test(nums))

Sample Output: 

Original list:
['1', '2', '3', '4', '5', '6', '7', '8']

Join adjacent members of a given list:
['12', '34', '56', '78']

Original list:
['1', '2', '3']

Join adjacent members of a given list:
['12']

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
