MULTIPLE CHOICE QUESTION

for x in range(3): for y in range(5): print(x, y)
for x in range(3): for y in range(3): print(x, y)
for x in range(5): for y in range(5): print(x, y)
for x in range(5): for y in range(3): print(x, y)
Answer explanation
The correct syntax for nested loops in Python is 'for x in range(5): for y in range(3): print(x, y)'. This code will iterate over x values from 0 to 4 and for each x value, it will iterate over y values from 0 to 2, printing the x and y values.

Explain with an example the syntax of nested loops in Python.
for i in range(3): print(i)
for i in range(2): for j in range(3): print(i, j)
for i in range(3): for j in range(3): print(i, j)
for i in range(3): for j in range(2): print(i, j)
Answer explanation
The correct syntax for nested loops in Python is 'for i in range(3): for j in range(2): print(i, j)'. It uses two 'for' loops to iterate over a range of values for 'i' and 'j', and then prints their values.

Provide an example of a nested while loop in Python.
while x < 5: y = 0 while y < 3: print(x, y) y += 1 x += 1
for x in range(5): for y in range(3): print(x, y)
while x > 5: y = 0
while x < 5: y = 3
Answer explanation
The correct choice is the first one. It demonstrates a nested while loop in Python, where the outer loop iterates while x is less than 5, and the inner loop iterates while y is less than 3. The print statement displays the values of x and y, and y is incremented by 1 in each iteration. Finally, x is incremented by 1 in each iteration of the outer loop.

Can you use a for loop inside a while loop in Python? If yes, explain with an example.
No, it is not possible
Yes, but it will cause an infinite loop
Yes, but only if the for loop is outside the while loop
Yes
Answer explanation
Yes, a for loop can be used inside a while loop in Python. For example, you can use a for loop to iterate over a list of elements while a certain condition is true.

Illustrate the concept of for loop inside a while loop with an example.
for i in range(3): j = 0 while j < 3: print(j, i) i += 1
for i in range(3): j = 0 while j < 3: print(j, i) j += 1
for i in range(3): j = 0 while j < 3: print(i, j) j += 1
for i in range(3): j = 0 while j < 3: print(i, j) i += 1
Answer explanation
The correct choice demonstrates a for loop inside a while loop, where the value of 'i' remains constant while 'j' increments from 0 to 2.
