The program must output the following: Welcome to Temperature Conversion Progran Enter the Celsius Temperature 26 The Fahrinheit temprature is:78.8 Thank You for Using The Temperature Conversion Program Post Lab Tasks: 1) Which of the following expressions will yield 0.5 ? a) 1/2 b) 1//2 c) 1.0//2 d) 2/2 2) 25%1 is a) 1 b) 2 c) 3 d) 0 3) 2.03 evaluates to a) 9 b) 8 c) 9.0 d) 8.0 4) 232 evaluates to a) 36 b) 18 c) 12 d) 81 5) What is the result of evaluating 2+23/2 ? a) 4 b) 6 c) 4.0 d) 6) What is the value of i printed? j=i=li+=j+j5 print(i) a) 1 b) 5 c) 6 d) 7) To add a value 1 to variable x, you write a) 1+x=x b) x+=1 c) x=1 d) x=+1 Lab Tasks: Task 1: For each of the following questions type in IDLE shell. Include screenshot of result. The first is done for your reference. 1) What will be displayed by the following code? x=5x=2x+1print(x) x=11 as , by precedence 25=10+1=11 2) Put parentheses in the expression below so that they show the precedence of operations: a=5+yorz>3andq==p 3) What are the values of a and b after this code? y=2.3a=int(y2)b=y%a 4) Calculate the values of the expressions. Indicate what type the answer is. a) 5+4(3.2+4.5) b) 7%5+12//7 c) 8+4.0 5) Why is this typecast redundant? x=str( input("what's your name?")) 6) For a=10 and b=4. print (ab) and print (a>>2). Show the calculations 7) Arrange the following operators in highest to lowest order of precedence? and,%, not, +, 8) Solve ((40+20)30)/10 9) Identify the correct arithmetic expression in Python: a) 11(12+13) b) 44(32) c) 5+43 d) (56)(7+8) Task 2: Create a new file on IDLE text editor. Save file as Lab2_task2.Write a program to calculate the area of a triangle using the Heron's formula. The user inputs float numbers as sides of a triangle. \begin{tabular}{|l|} \hline Heron's Formula \\ x=2a+b+c \\ tesa =(sa)(sb)(sc) \\ \hline \end{tabular} Task 3: Write a program to get an integer input from the user and print it's: - the hex equivalent - square root - cube - digit at one's place
