Python program to find all the prime numbers in the given range- by Mahesh Huddar

Great

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?

Thank you sir





..

thank you

so simple

Thank you sir ji

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}"

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!!.

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

Sir what if the start value is 2

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

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 ) ...

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)

How to sum all the prime numbers what will we get in results

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

Non prime numbers how to print

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?

🥺

why is my program not working??!!

What is meant by flag=0?

i want the next prime number to be printed plz help

I want comma in between numbers. What can I do

(Get the range from the user)... Whats the range?
