how to print prime numbers in python code example
Example 1: prime number in python
def prime(num):
if num>1:
s=int(num/2)
for i in range(2,s+1):
if num%i==0:
return("not prime")
break
return("prime")
print(prime(239))
Example 2: python calculate prime numbers until numer
until = 20
[n for n in range(2, until) if all(n % m != 0 for m in range(2, n-1))]
Example 3: list of prime numbers in python
n = 20
primes = []
for i in range(2, n + 1):
for j in range(2, int(i ** 0.5) + 1):
if i%j == 0:
break
else:
primes.append(i)
print(primes)
Example 4: prime number program python
lower = 900
upper = 1000
print("Prime numbers between", lower, "and", upper, "are:")
for num in range(lower, upper + 1):
if num > 1:
for i in range(2, num):
if (num % i) == 0:
break
else:
print(num)Copied
