To write a Python program to find first n prime numbers.

 Aim:

To write a Python program to find first n prime numbers.

Algorithm:

1. Read the value of n

2. for num in range(0,n + 1), perform the following

3. if num%i is 0 then break

else print the value of num

4. Repeat step 3 for i in range(2,num)

Program:

n = int(input("Enter the upper limit: "))

print("Prime numbers are")

for num in range(0,n + 1):

# prime numbers are greater than 1

if num > 1:

for i in range(2,num):

if (num % i) == 0:

break

else:

print(num)

Sample Output:

 $python main.py Enter the upper limit: 20 Prime numbers are 2 3 5 7 11 13 17 19
