Finding nearest square in python using for loop-CodePudding

I wrote a program to find the nearest square in python using while loop, which goes like the below:

num = 0
while (num 1)**2 < limit:
    num  = 1
nearest_square = num**2
print(nearest_square)

This made me wonder, if we can find the same using a for loop. I am unable to understand how can we set the range of the same.

Can anyone please guide?

Thanks in advance.

This is probably the best way to find the nearest square.

int(limit ** (0.5)) ** 2

If limit = 200 then the output is 196.

But if you want to do the exact same thing you did above using for loop use this,

for num in range(limit   1):
  if (num   1) ** 2 >= limit:
    break

IIUC:

for num in range(round(limit**0.5) 1):
    if (num 1)**2 >= limit:
        break
nearest_square = num**2
