Python Program to Find Nth Prime Number

6 years ago

I have written this code in Python to print Nth prime number.

Python Code:


from math import sqrt
num=1
count=0
N=0
def prime(n):
      sqroot=int(sqrt(n))
      j=2
      while j<=sqroot:
            if n%j==0:
                  return False
            j=j+1
      return True

N=int(input('Number : '))
while(True):
      num=num+1
      if prime(num):
            count=count+1
      if count==N:
            print(count,'th prime is ',num)
            break

from math import sqrt

num=1

count=0

N=0

def prime(n):

sqroot=int(sqrt(n))

j=2

while j<=sqroot:

if n%j==0:

return False

j=j+1

return True

N=int(input('Number : '))

while(True):

num=num+1

if prime(num):

count=count+1

if count==N:

print(count,'th prime is ',num)

break

Output:
