# Python Program to Print Prime Number From 1 to N

Python program to print prime numbers from 1 to n; Through this tutorial, i am going to show you how to print prime number from 1 to N (10, 50, 100, 1000) using for loop, while loop.

And as well as, i am going to show you how to print sum of prime numbers from 1 to N (10, 50, 100, 1000) in python program.

## Python Program to Print Prime Number From 1 to N (10, 50, 100, 1000)

Let’s see the following python programs to print prime numbers from 1 to N (10, 50, 100, 1000); as shown below:

• Python Program to Check Prime Number using For Loop
• Python Program To Print Numbers From 1 to N Using For Loop
• Python Program To Print Numbers From 1 to N Using While Loop
• Sum of prime numbers in python using for loop

### Python Program to Check Prime Number using For Loop

```Python Program to Check A given Number is Prime Or Not
Num = int(input(" Please Enter any Number: "))
count = 0
for i in range(2, (Num//2 + 1)):
if(Num % i == 0):
count = count + 1
break
if (count == 0 and Num != 1):
print(" %d is a Prime Number" %Num)
else:
print(" %d is not a Prime Number" %Num)```

Output

```Please Enter any Number:  50
50 is not a Prime Number ```

### Python Program To Print Numbers From 1 to N Using For Loop

```# Python Program to print n prime number using for loop

Number = int(input(" Please Enter any Number: "))
print("Prime numbers between", 1, "and", Number, "are:")
for num in range(1, Number + 1):
# all prime numbers are greater than 1
if num > 1:
for i in range(2, num):
if (num % i) == 0:
break
else:
print(num)

```

Output

```Please Enter any Number:  25
Prime numbers between 1 and 25 are:
2 3 5 7 11 13 17 19 23 ```

### Python Program To Print Numbers From 1 to N Using While Loop

```# Python Program to print Prime Numbers from 1 to N

max = int(input(" Please Enter Any Number: "))
Number = 1
print("Prime numbers between", 1, "and", max, "are:")
while(Number <= max):
count = 0
i = 2

while(i <= Number//2):
if(Number % i == 0):
count = count + 1
break
i = i + 1
if (count == 0 and Number != 1):
print(" %d" %Number, end = '  ')
Number = Number  + 1```

Output

```Please Enter Any Number:  15
Prime numbers between 1 and 15 are:
2   3   5   7   11   13

```

### Sum of prime numbers in python using for loop

```# Python Program to print n prime number using for loop

max = int(input("Find sum of prime numbers upto : "))
sum = 0
for num in range(2, max + 1):
i = 2

for i in range(2, num):
if (int(num % i) == 0):
i = num
break;
#If the number is prime then add it.
if i is not num:
sum += num
print("\nSum of all prime numbers upto", max, ":", sum)

```

Output

```Find sum of prime numbers upto :  25
Sum of all prime numbers upto 25 : 98   ```
