Python: Add a number to each element in a given list of numbers
Python List: Exercise - 174 with Solution
Write a Python program to add a number to each element in a given list of numbers.
Sample Solution:
Python Code:
def add_val_to_list(lst, add_val):
result = lst
result = [x+add_val for x in result]
return result
nums = [3,8,9,4,5,0,5,0,3]
print("Original lists:")
print(nums)
add_val = 3
print("\nAdd",add_val,"to each element in the said list:")
print(add_val_to_list(nums, add_val))
nums = [3.2,8,9.9,4.2,5,0.1,5,3.11,0]
print("\nOriginal lists:")
print(nums)
add_val = .51
print("\nAdd",add_val,"to each element in the said list:")
print(add_val_to_list(nums, add_val))
Sample Output:
Original lists: [3, 8, 9, 4, 5, 0, 5, 0, 3] Add 3 to each element in the said list: [6, 11, 12, 7, 8, 3, 8, 3, 6] Original lists: [3.2, 8, 9.9, 4.2, 5, 0.1, 5, 3.11, 0] Add 0.51 to each element in the said list: [3.71, 8.51, 10.41, 4.71, 5.51, 0.61, 5.51, 3.62, 0.51]

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))
