here is code but I don't understand 2nd for loop how it print 2,3 because for i in range(2,2) don't work

Answer 2

@choe else is outside for loop You mean to say that i is nothing so it will print 2

Answer 3

when num is 2, i is nothing. Nested loops cant output these values, but the else on the loop is what is printing 2 since your condition inside wasnt satisfied.

for num in range(lower,upper+1):
for i in range(2,num):
if(num%i==0):
break
else:
print(num)

this should give you something different.
