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.):
- Plotting in Python ✅
- Subplots✅
- Exercises✅
- If ... Else
- Arrays
- For Loops
- Nested
- For Loops
- While Loops
- Exercises
- Creating Functions in Python - Introduction
- Functions with multiple return values
- Exercises
- Creating Classes in Python
- The init () Function
- Exercises
- Creating Python Modules
- Exercises
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

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