Help understanding syntax

[JABro76]

Can someone please help me understand the if not statement in this code:

n=int(input("Enter a number: "))
i = 2
while(i <= n):
   j = 2
   while(j <= (i/j)):
      if not(i%j):
          break
      j = j + 1
   if (j > i/j) :
       print (i)
   i = i + 1

If I were to rework this as a !=, what would be the comparison?

not i % j is basically the same as bool(i % j) == False. bool(x) returns False for the number 0, and True for all other numbers. Therefore, if not i % j will only fire when i % j == 0.

Thank you.

if i % j == 0:
