Day 76 [November 24, 2025]

I need to buckle down, as I'm still lagging on day day 3 & 4 goals, "Day 3-4: Control structures (if-else, loops)", as well as day 5 (and 6) goals, "Day 5-6: Functions and modules", and Day 7 target (exercises) (Meta AI, personal communication, August 8, 2025). If I haven't covered this, I can't make progress on day 8 - 75 goals.

Goals:
As extracted from the 'Python for Software Development' textbook by Halvorsen (n.d.):

Notes:
Python for Data Science, AI & Development Course (IBM) (Santarcangelo, n.d.):
Module 2: Python Data Structures

Lists and Tuples
Dictionaries
Sets

Sets:

used for the storage of values that are distinct
"append() adds an object as a single element, while extend() adds each element of an iterable individually". Check using the code below:

list = [2,3,4]
list.append([3])
print(list)

list2 = [2,3,4]
list2.extend([3]) #note the difference here
print(list2)

Outputs:
[2, 3, 4, [3]]
[2, 3, 4, 3]

Otherwise,
list2 = [2,3,4]
list2.extend(3) #note the difference here
print(list2)
will give TypeError: 'int' object is not iterable

Both sum() and len() functions work for Tuples, but the difference is sum() adds the elements (must be int or float type), while len() counts the elements.

ages = (20,3,34)
print(sum(ages))
print(len(ages))

Outputs:
57
3
