Here is my code.
#Prime numbers between 0-100
for i in range(2,100):
flg=0
for j in range(2,int(i/2)):
if i%j==0:
flg=1
break
if flg!=1:
print(i)
And the output is
2
3
4 <-
5
7
11
13
17
19
23
29
31
37
41
43
47
53
59
61
67
71
73
79
83
89
97
I have no idea why there is this 4. Pardon me if i made some noobish mistake, as i can't seem to figure it out.
The reason is that range is not inclusive, ie
>>> range(2,2)
[]
So when you access 4, you don't check for divisors. Change for example to range(2,int(i/2)+1)
To speed up your calculation, you can use math.sqrt instead of /2 operation, for example as:
import math
and then
for j in range(2, int(math.sqrt(i)+1)):
