Answer:

Explanation:

First for loop, loops a between number 4 to 17 (not including 17), and second for loop, loops b between 0 to 4. The print statement prints out 'a', so when a = 4, the second loop, loops 4 times, so the number is printed 4 times, when a = 5, the second loop, loops 5 times, so the number is printed 5 times, and so on for the other numbers, until 16, the first loop ends.

Answer 2

Corrected Códe:-

for a in range ( 4,17):

for b in range (a):

print( a,end=' ')

print()

Output:-

• Given in attachment

Explanation:-

• Outer loop runs from 4 to 16 (17 is not included)
• inner loop runs from 1 to 1 less than the value of outer loop
• value of outer loop is printed with spaces
• once inner loop becomes equal to outer loop, inner loop terminates
• print() will move the cursor to next line.
• Same process repeats until outer loop becomes 17
• once the outer loop becomes 17, loop terminates.
• Hence, the program ends :)
