how to find prime numbers in a range in python code example

Example 1: find prime number in given range in python

#not made by me but a person name "Concerned Cod" i put only input in it so it makes easy to copy-paste LOL
start = int(input("enter start range : "))
end = int(input("end range : "))
 
for i in range(start,end):
  if i>1:
    for j in range(2,i):
        if(i % j==0):
            break
    else:
        print(i)

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: the list of prime number in a given range python

n=int(input("Enter the number till you want to check: "))
primes = []
for i in range (2, n+1):
    for j in range(2, i):
        if i%j == 0:
            break
    else:
        primes.append(i)
print(primes)

Example 4: 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)
