## Problem Statement:

Write a Python program to print prime numbers from 1 to n.

### OR

Write a Python program to print prime numbers in a given range.

## Program:

##To print prime number between 1 to n
## Prime Number is a number which is divisible only by 1 and itself.
def prime(n):
prime_list = []
if n in (0,1):
return "Number is not a prime number"
for x in range(2,n+1): ## Loop for all the number from 2 to n
## A counter to check if the number is divisible or not inside the for loop
counter=0
## Start the loop from 2 to n-1. In range the loop is executed till n-1. Also we have given the start range.
for each in range(2, x):
if x % each == 0: ## checks if the number is divisible by any other number in this loop.
counter += 1 ## If yes counter is incremented.
## If the counter is incremented that means the number is divisible inside the loop. If the counter is zero means it is a Prime Number.
if counter == 0:
prime_list.append(x)
return prime_list
if __name__ == '__main__':
num = int(raw_input("Enter a number"))
result = prime(num)
print result
## Output:

Enter a number 10
