Comparison of strings is lexicographically-sensitive

Day 78 [December 2nd, 2025 started reading around 12am]

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 - 77 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 Programming Fundamentals

Conditions and Branching

• The block of code under if statement only run when the if condition is True


• Comparison of strings is lexicographically-sensitive (comparison is done one a character by character basis dependent on how the characters are ordered in Unicode or ASCII) (see also Google, 2025a; Google, 2025b). That's why "10"<"7" evaluates to True (the first characters are compared).

Summary:

Comparison of strings is lexicographically-sensitive.
