Van Roberts · Answer 1

n=int (input ("Enter number upto which you want to print prime numbers:/n")) #taking input of n in integer type ...

for i in range (1, n) : #looping over 1 to n.

pr=True #taking pr to be True ...

for div in range (2, i) : #looping over 2 to i ...

if i%div==0:#if i is divisible by div then it is not prime

pr=False#making pr false

if pr and i!=1: #condition for printing

print (str (i)) #printing the prime numbers ...

Explanation:

In the python program we have checked for every integer up to n that is is not divisible by any integer between 2 to n-1 both inclusive if it is then it is not a prime number.
