Python Program to print Prime Numbers from 1 to 100

by

Write a Python Program to print Prime numbers from 1 to 100, or 1 to n, or minimum to maximum with example. Here, we will calculate the sum of prime numbers from 1 to n

TIP: I suggest you to refer Prime Number article to understand the logic.

Python Program to print Prime Numbers from 1 to 100 using For Loop

This python program will print prime numbers form 1 to 100.

First, we used For Loop to iterate loop between 1 and 100 value. Within the for loop,

  • We used another For loop to check whether the number is divisible or not. If true, count will be incremented, and break statement will skip that number
  • Next, If statement is to check whether the count is zero, and given number is not equal to 1. If it is true, it will print the number because it is a prime Number
# Python Program to print Prime Numbers from 1 to 100
 
for Number in range (1, 101):
    count = 0
    for i in range(2, (Number//2 + 1)):
        if(Number % i == 0):
            count = count + 1
            break

    if (count == 0 and Number != 1):
        print(" %d" %Number, end = '  ')

OUTPUT

Python Program to print Prime Numbers from 1 to 100 using While Loop

We just replaced the For loop in the above example with While loop.

# Python Program to print Prime Numbers from 1 to 100
 
Number = 1

while(Number <= 100):
    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

Python Program to print Prime Numbers from 1 to N using For Loop

Instead of blindly printing prime numbers from 1 to 100, this program allow user to enter the minimum and maximum values. Next, it will print prime numbers between Minimum and Maximum values.

 # Python Program to print Prime Numbers from 1 to N
 
minimum = int(input(" Please Enter the Minimum Value: "))
maximum = int(input(" Please Enter the Maximum Value: "))

for Number in range (minimum, maximum + 1):
    count = 0
    for i in range(2, (Number//2 + 1)):
        if(Number % i == 0):
            count = count + 1
            break

    if (count == 0 and Number != 1):
        print(" %d" %Number, end = '  ')

Python Program to print Prime Numbers from 1 to N using While Loop

This program is same as above. We replaced the For loop with While Loop.

 # Python Program to print Prime Numbers from 1 to N
 
minimum = int(input(" Please Enter the Minimum Value: "))
maximum = int(input(" Please Enter the Maximum Value: "))

Number = minimum

while(Number <= maximum):
    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

Python Program to find Sum of Prime Numbers from 1 to 100

This program finds the prime numbers between 1 and 100. Next, its going to add those number to find the sum of prime numbers between 1 and 100.

 # Python Program to find Sum of Prime Numbers from 1 to N
 
minimum = int(input(" Please Enter the Minimum Value: "))
maximum = int(input(" Please Enter the Maximum Value: "))
total = 0

for Number in range (minimum, maximum + 1):
    count = 0
    for i in range(2, (Number//2 + 1)):
        if(Number % i == 0):
            count = count + 1
            break

    if (count == 0 and Number != 1):
        print(" %d" %Number, end = '  ')
        total = total + Number

print("\n\nSum of Prime Numbers from %d to %d = %d" %(minimum, maximum, total))

Python Program to find Sum of Prime Numbers from 1 to N

This will allows the user to enter Minimum and Maximum values. Next, it will find the sum of prime numbers between Minimum and Maximum values

 # Python Program to print Prime Numbers from 1 to N
 
minimum = int(input(" Please Enter the Minimum Value: "))
maximum = int(input(" Please Enter the Maximum Value: "))
total = 0

Number = minimum

while(Number <= maximum):
    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 = '  ')
        total = total + Number
    Number = Number  + 1
        
print("\n\nSum of Prime Numbers from %d to %d = %d" %(minimum, maximum, total))
