Q-1: After completing the reading, what concepts are still unclear to you? If nothing is unclear, what did you find most interesting?
- prob = random.randrange(1, 101)
- This will generate a number between 1 and 101, but does not include 101.
- prob = random.randrange(1, 100)
- This will generate a number between 1 and 100, but does not include 100. The highest value generated will be 99.
- prob = random.randrange(0, 101)
- This will generate a number between 0 and 100. The lowest value generated is 0. The highest value generated will be 100.
- prob = random.randrange(0, 100)
- This will generate a number between 0 and 100, but does not include 100. The lowest value generated is 0 and the highest value generated will be 99.
Q-1: (TEST) The correct code to generate a random number between 1 and 100 (inclusive) is:
In statistical physics, it is common to use Stirling’s approximation for \(N!\),
Obtain an integer from the user, assign it to
N, and print out, in order,
\(N!\), Stirling’s approximation, and the relative percent
error. The relative percent error is calculated as
For a right triangle we have
Compute and print \(\theta\) for
Hint: use the function
atan2() instead of
Use the double angle formula,
to compute and print
- import math
- Correct! This will make it obvious to anyone who reads your code when you use something from the ``math`` module.
- from math import exp
- This imports only the ``exp()`` function and puts it in the global namespace. This can make it difficult to tell where this function comes from.
- from math import *
- This imports everything from ``math`` and puts it in the global namespace. This can make it difficult to tell when the ``math`` module is being used.
- import math as m
- Don't change the names of modules unless it is the convention for that module. This makes your code harder to read.

Write a program to convert square km to square meters.
In mathematics, the Leibniz formula for π, named after Gottfried Leibniz, states that
Write a program to calculate π when n is 99 and 999. When n becomes bigger, does π becomes more accurate?
Write a program to print an n*n times table. n could be any number. For example, the following is a 5*5 times table:
1 x 1 = 1
1 x 2 = 2 2 x 2 = 4
1 x 3 = 3 2 x 3 = 6 3 x 3 = 9
1 x 4 = 4 2 x 4 = 8 3 x 4 = 12 4 x 4 = 16
1 x 5 = 5 2 x 5 = 10 3 x 5 = 15 4 x 5 = 20 5 x 5 = 25
Write a Python program to print 10 random integers between 1 and 100, inclusive. Print one random integer per line. Use a loop. I have started the program for you.
