Pictorial Presentation:

Python: Access the index of a list

Sample Solution:

Python Code:

nums = [5, 15, 35, 8, 98]
for num_index, num_val in enumerate(nums):
    print(num_index, num_val)

Sample Output: 

0 5                                                                                                           
1 15                                                                                                          
2 35                                                                                                          
3 8                                                                                                           
4 98

Explanation:

In the above exercise -

nums = [5, 15, 35, 8, 98] - initializes a list of numbers with 5 elements.

for num_index, num_val in enumerate(nums): - This is a for loop that iterates over each element of nums and returns both the index of the element and the value of the element using the enumerate function.

print(num_index, num_val) – This line prints out the index and value of each element in nums using the print() function.

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
