Summing Integers Function

• A function called sumUp() prompts the user for an integer n and calculates the sum of integers from 1 to n inclusive.
• It assumes that n is greater than or equal to 0.
• For example, if the input is 5, the function returns 15 (1+2+3+4+5).
• If the input is 10, the function returns 55.
• If the input is 0, the function returns 0.
• The function initializes a variable sum to 0.
• It iterates through numbers from 1 to n (inclusive), adding each number to the sum.

Multiplying Integers Function

• A function called multUp(n) calculates the multiplication of all integers from 1 to n inclusive.
• It assumes that n is greater than 0.
• For example, multUp(3) returns 6 (1 * 2 * 3).
• multUp(6) returns 720.
• multUp(1) returns 1.
• The function initializes a variable mult to 1.
• It iterates from 1 to n (inclusive), multiplying mult by each number.

Selective Multiplication Function

• A function called sel_multUp(L, n) takes a list of integers L and an integer n as input.
• It returns the product of all integers in L that are divisible by n with no remainder.
• It assumes all numbers in L are integers greater than or equal to zero.
• It also assumes that there is at least one number in L divisible by n.
• For example, given the list L = [9, 4, 3, 17, 2] and n = 3, the function returns 27 (9 * 3).
• Given L = [6, 4, 12, 7] and n = 4, it returns 48 (4 * 12).
• The function initializes a variable mult to 1.
• It iterates through each number i in the list L.
• If i is divisible by n (i.e., i % n == 0), it multiplies mult by i.

String Length Function

• A function called my_len_string(S) calculates the length of the string S.
• For the string "Go Ducks!", would return "The length of the string Go Ducks! is 9".
• For the string "MIS-110", would return "The length of the string MIS-110 is 7".
• The function initializes a variable count to 0.
• It iterates through each character i in the string S (This is an error in the source text, it should iterate through L).
• It increments count for each character.
• Finally, print "The length of the string", S, "is", count.

Range Test Function

• The function range_test() demonstrates the use of the range() function.
• x = list(range(2, 10, 3)) creates a list of numbers starting from 2, up to (but not including) 10, with a step of 3, resulting in [2, 5, 8].
• y = list(range(15, 2, -1)) creates a list starting from 15, down to (but not including) 2, with a step of -1, resulting in [15, 14, 13, 12, ..., 3].
• z = list(range(4)) creates a list starting from 0, up to (but not including) 4, with a default step of 1, resulting in [0, 1, 2, 3].
• The outputs of x, y, and z are then printed.

Mystery Function

• The function mystery1(x, y) performs a series of calculations based on the inputs x and y.
• If x = 2 and y = 5:
  • a = x * y results in 10.
  • b = y // x results in 2.
  • c = x % y results in 2.
  • d = (x + y) % 4 results in 3.
  • answer = (a // d) * (b % (c + 1)) which is (10 // 3) * (2 % 3) which equals 3 * 2 = 6
• The function returns the value of answer, which is 6.

Temperature Function

• The function temperature() prompts the user to enter a temperature.
• If the temperature is 80 or above, it prints "Let's go to the Jersey Shore".
• If it's between 60 and 80 (exclusive), it prints "Cookout Time!".
• If it's between 40 and 60 (exclusive), it prints "Getting cool".
• If it's between 20 and 40 (exclusive), it prints "Time to go skiing??".
• If it's exactly 15, it prints "Its 15 degrees".
• Otherwise, it prints "Anyone ready for a trip to Florida?".
• If the input is 39, the output is "Time to go skiing??".

Another Mystery Function

• The mystery3() function initializes x to 0 and y to 3.
• It then iterates through the range from 0 to to 11 (exclusive), incrementing by 2 each time.
• Inside the loop, it prints the product of x and y and then increments x by 1
• The loop will go through these steps:
  • i = 0: prints x * y (0 * 3 = 0), x becomes 1
  • i = 2: prints x * y (1 * 3 = 3), x becomes 2
  • i = 4: prints x * y (2 * 3 = 6), x becomes 3
  • i = 6: prints x * y (3 * 3 = 9), x becomes 4
  • i = 8: prints x * y (4 * 3 = 12), x becomes 5
  • i = 10: prints x * y (5 * 3 = 15), x becomes 6

Mystery Function with Rounding

• The mystery(n, k) function calculates A as the integer division of n by k (n//k).
• It calculates B as the remainder of n divided by k (n%k).
• It calculates the sum of numbers from 0 to 9.
• It then calculates x as A + B + sum.
• Finally, it returns x rounded to 3 decimal places.

Odd or Even Function

• The OddEven(n) function checks if a number n is even or odd.
• If n is divisible by 2 (i.e. n % 2 == 0), it prints "Number is even.".
• Otherwise, it prints "Number is odd.".

Loop Functions: String, List, Range

• LoopString(S) iterates through each character i in the string S and prints each character on a new line.
• LoopList(L) iterates through each element i in the list L and prints each element on the same line, separated by a space.
• LoopRange(n) iterates through the numbers from 0 to n-1 and prints each number on the same line, separated by a space.

Input and Print Function

• The InputPrint() function prompts the user for their name, age, and favorite float.
• It then prints a formatted string with the collected information, rounding the float to 2 decimal places.

Simple Sum Function

• The simpleSum(x, y) function calculates the sum of two numbers x and y.
• It prints the sum.
• It can optionally return the sum.

Main Function

• The main() function prompts the user to enter two numbers.
• It then prints the sum of the two numbers
• The statement main() executes the code within the main Function
