It's helpful to see a few of the ways we would want to use these concepts.

So, this bit of code here:

This is written out, verbatum, what is going on in loop logic

my_str = "My String!"
upper_case_count = 0
if my_str[0].isupper():
  upper_case_count += 1
if my_str[1].isupper():
  upper_case_count += 1
if my_str[2].isupper():
  upper_case_count += 1
if my_str[3].isupper():
  upper_case_count += 1
if my_str[4].isupper():
  upper_case_count += 1
if my_str[5].isupper():
  upper_case_count += 1
if my_str[6].isupper():
  upper_case_count += 1
if my_str[7].isupper():
  upper_case_count += 1
if my_str[8].isupper():
  upper_case_count += 1
if my_str[9].isupper():
  upper_case_count += 1
  
print(upper_case_count)

Can be simplified with using loops, like so:

Much more compact code

Another nifty thing you can accomplish with a bit of loop logic and Python keyword shortcuts:

This is some basic pattern matching
