Con of high-level programming languages?

When run, programs tend to be slower than ones written with low-level languages.

for n in range(9, 20, 3):

When the loop begins, the counter variable n is assigned the start value of 9. After each iteration of the loop, the value of n increments by 3, which is the change value. The loop repeats if the value of the counting variable n is less than 20, the end value. Therefore in the loop, n will have the values of 9, 12, 15, and 18. BASICALLY, 9 is the number that counting begins on, 20 IS THE NUMBER BEFORE IT STOP SO 19 IS THE LAST NUMBER, 3 IS THE NUMBER IT INCREASES BY.

When you know the exact number of repetitions needed.

What do we mean by "programmers are gatekeepers"?

Writing and owning a program involves testing, debugging, and resolving any issues to make sure the program is working for the user.

Written in machine code, which is challenging for humans to understand.

How does memory play a role with int and float?

You may be working with a program that tends to take up a lot of storage space on your computer. Floating point numbers take more space than integers. Example: If you can use 1 instead of 1.0, you can save yourself some memory.

How does precision play a role with int and float?

You may need to have a specific number that requires decimals. Floating point numbers allow for more precision than integers.

How does arithmetic play a role with int and float?

You may need to have the correct math. The results of integer math and floating point math aren't always the same. Example: 11/5=? Python will tell you the answer to this question is 2. If you change the numbers to decimals, you'll get a different answer: 11.0/5.0 = 2.2.
