Python : Looping Statement Test 4

Python : Looping Statement Test 4

Q1. What is the use of range function in python?

Q2. Name three jump statements in python and explain any one.

Q3. Write the output of the following program.

Code	Output
x = "123" for i in x:   print(i)
i=8 while True:   if i%3==0:     break   print("A")
i=9 while True:   if i%3==0:     break   print("A")
i=0 while i<3:   print(i)   i=i+1 else:   print(0)
i=0 while i<3:   print(i)   i=i+1 print(0)
i=0 while i<3:   print(i)   i=i+1   print(0)
i=2 for x in range(i):   i+=1   print(i)   print(i)
i=2 for x in range(i):   x+=1   print(x) print(x)
i=2 for x in range(i):   x+=1   print(x)   print(x)
i=100 while i<57:   print(i)   i+=5
i=100 while i>57:   print(i+1)   i+=5

 

Q4. Write the output and convert it into for loop.

i=100

while i>57:

               print(i)

               i-=5

 

 

Solution of Q3.

Code	Output
x = "123" for i in x:   print(i)	1 2 3
i=8 while True:   if i%3==0:     break   print("A")	Infinite loop
i=9 while True:   if i%3==0:     break   print("A")	No Output
i=0 while i<3:   print(i)   i=i+1 else:   print(0)	0 1 2 0
i=0 while i<3:   print(i)   i=i+1 print(0)	0 1 2 0
i=0 while i<3:   print(i)   i=i+1   print(0)	0 0 1 0 2 0
i=2 for x in range(i):   i+=1   print(i)   print(i)	3 3 4 4
i=2 for x in range(i):   x+=1   print(x) print(x)	1 2 2
i=2 for x in range(i):   x+=1   print(x)   print(x)	1 1 2 2
i=100 while i<57:   print(i)   i+=5	No Output
i=100 while i>57:   print(i+1)   i+=5	Infinite loop

    If the percentage is less than 75, than            student will not be able to sit in exam.

Q2. Accept the marks from the user and display the

    grade according to the following criteria:

    a. Below 25 - D

    b. 25 to 45 - C

    c. 45 to 50 - B

    d. 50 to 60 – B+

    e. 60 to 80 - A

    f. Above 80 – A+

Q3. A company decided to give bonus to employee 

    according to following criteria:

    Year of Service               Bonus

    More than 10 years            10%

    >=6 and <=10                  8%

    Less than 6 years             5%
