1.	Write a Python script that display 20 Mersenne Prime Numbers ?
Answer» def Mersenne (n): return 2** n-1 def test prime (n): mid = n/2 + 1 for t in range (2, mid): if n%t = = 0: return false else : return true print “20 Mersenne Prime Numbers are :” for a in range (1,21): number = Mersenne (a) prime = test prime (number) if prime : print number, “Prime” else : print number

Answer»

def Mersenne (n):

return 2** n-1

def test prime (n):

mid = n/2 + 1

for t in range (2, mid):

if n%t = = 0:

return false

else :

return true

print “20 Mersenne Prime Numbers are :”

for a in range (1,21):

number = Mersenne (a)

prime = test prime (number)

if prime :

print number, “Prime”

else :

print number
