Question

1) What is the output of the following program? Kindly trace the program by hand I will be asking similar questions in the final exam, you will not have computer to run the code you will have to answer the same by tracing the code. So practise now? 10 Points La lab6.py - C:/Users/sanjay/Documents/Couse2 File Edit Format Run Options Window Help #a i = 1 while i<=4: print ("*"*i) i = i +1 "* #b i = 1 j = 2 while i>=1: a = " "*j+"*"*i+" print (a) i = 1+2 j = j-1 if i>5: break i = 3 j = 1 while i>=1: a = " "*+"*"*i+" print (a) i = i-2 j = 3+1 "*j

Kindly show the steps please. thank you

Answer 1

Task 1

1. Code with explanation

i = 1                   #initializing i with 1

while i<=4:             #applying loop for iteration for condition i less or equal to 4

    print ("*"*i)       #printing pattern

    i = i+1             #incrementing i with 1 after each iteration

Output

Process finished with exit code 0

2. code with explanation

i = 1                      #initializing i with 1

j = 2                      #initializing j with 2

while i>=1:                #applying loop for iteration for condition i greater or equal to 1

    a = " "*j+"*"*i+" "*j  #multiplying space and asterisk with variable i and j to print pattern 

    print (a)              #printing pattern

    i=i+2                  #incrementing i with 2

    j=j-1                  #decrementing j with 1

    if i>5:                #applying condition that if i greater then 5 then go out of loop using break

        break

        

        #upper block will provide first three lines of pattern

        #lower block will provide last two lines

i = 3                      

j = 1

while i >= 1:

    a = " "*j+"*"*i+" "*j

    print (a)

    i = i-2                 #decrementing i with 2

    j = j+1                 #incrementing j with 1

Output

Process finished with exit code 0

Explanation

in part a)

• we have used simple while loop to print a specific pattern as shown in output snippet of part 1
• starting with I initialize with 1
• and on that I apply while loop upto I is less then or equal to 4
• printing “*” into value of I times
• incrementing i

in part b)

• we have used two while loops to print a pattern with first increasing “*” and then decreasing as shown in output of part 2.
• In first while loop we have printed three lines of asterisk with number of spaces depending upon size of j and number of asterisk depending upon size of i.
• In second while loop we have printed 2 lines of asterisk decrementing accordingly as shown in output snippet of part 2.
