start is taken from 1, it also includes 1 but 1 is not a prime number

[ranjithv]

this is too complex . Try this instead

n=int(input('enter the number range'))
for i in range(2, n+1, 1):
for j in range(2, i, 1):
if i%j==0:
break
else:
print(i)

[Swamy]

Sir, in the code, why can't we give break statement immediately after if (i%j==0) is true.Why do we need to include flag=1?

[musaddiqali]

When the interval from start to end is very large, like in lakhs of numbers, then this program will take more time to compute. In that case, I came to know that the fastest method may be Sieve Of Eratosthenes method. Can you please explain this same program using Sieve of Eratosthenes method?

How do I print prime numbers from 1 to 1000, in group of 10's? like 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, then another 10 prime numbers….in python

[garvgoel]

def count_primes(initial, final):
numberOfPrimes=0
for _ in range(initial, final+1):
if _==1:
continue
if _ in [2, 3, 5, 7] or (_%2 !=0 and _%3 !=0 and _%5 !=0 and _%7 !=0):
print(_)
numberOfPrimes +=1
return f"No. of prime numbers are {numberOfPrimes}"

[rithickdharmaraj]

Boss, I need help .. my starting is 14 and ending is 16, , , there is no output .... But I need output as (no prime between the range ) ...

[sarlengunavathy]

I want the code to show the available prime numbers, the number of prime numbers and the sum of all prime numbers

[Aryansingh-fkhy]

I am even getting 0 or 1 while initializing the start variable with the value 0 or 1 as per the given code in the video, as both are not prime numbers, so the code is missing some statements, so please rectify that!!.
