Python loops

The program above:

• prints all the odd numbers between 1 and 20

• prints all even numbers between 1 and 20

• print all the odd numbers between 1 and 21

• prints all the even numbers between 1 and 21

How many times the following loop will execute:

i = 1

while True:

print(i)

i += 2

• 0

• 2,4,6,8,..................

• 1,3,5,7,9,.............

• 1,2,4,6,8......................

for loop in python works on:

• 1.range

• 2.iteration

• 3.Both of the above

• 4.None of the above

i = 1

while True:

if i%7 == 0:

break

print(i)

i += 1

• 123456

• 1234567

• error

• none

i = 1

while False:

if i%2 == 0:

break

print(i)

i += 2

• 1

• 1357......

• 1234......

• none of the mentioned

x = 123

for i in x:

print(i)

• 1 2 3

• 123

• error

• none of the above

for i in range(10):

if i == 5:

break

else:

print(i)

else:

print("Here")

• 01234 Here

• 012345 Here

• 01234

• 12345

string = "my name is x"

for i in string:

print (i, end=", ")

• m, y, , n, a, m, e, , i, s, , x,

• m, y, , n, a, m, e, , i, s, , x

• my, name, is, x,

• error

x = 'abcd'

for i in range(len(x)):

print(i.upper())

• a b c d

• 0 1 2 3

• error

• 1 2 3 4

x = 'abcd'

for i in range(len(x)):

x = 'a'

print(x)

• a

• abcd abcd abcd

• a a a a

• none
