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
