Python - Please help!

Margaret [11]

Answer:

i= 1

for i in range(1,n):

if i * i < n:

print(2* i + 1)

i += 1

else:

print('Hakuna Matata')

Explanation:

First, there's a need to rewrite the code segment in your question (because of indentation)

i= 1

while i*i < n:

print(2* i + 1)

i += 1

else:

print('Hakuna Matata')

The explanation of the equivalent of the above while loop is as follows

This line initializes i to 1

i= 1

This line iterates from 1 to n-1

for i in range(1,n):

This line checks if i * i is less than n

if i * i < n:

The following line is executed if the above condition is satisfied; otherwise, nothing is done

print(2* i + 1)

The value of i is incremented by 1 using this line

i += 1

The following is executed at the end of the iteration

else:

print('Hakuna Matata')

Note: Assume any value of n, both programs display the same output
