Write a Python Program to print Prime numbers from 1 to 100, or 1 to n, or minimum to maximum with example. In this Python program, we also calculate the sum of prime numbers from 1 to n.
Python Program to print Prime Numbers from 1 to 100 using For Loop
This python program display the prime numbers from 1 to 100.
First, we used For Loop to iterate a loop between 1 and 100 values. Within the for loop,
- We used another For Loop to check whether the number is divisible or not. If true, count incremented, and break statement skip that number.
- Next, if statement checks whether the count is zero, and the given number is not equal to 1. If it is true, it prints the number because it is a Prime Number.
TIP: I suggest you refer to the Prime Number article to understand the Python logic.
# 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 = ' ')
Python Program to print Prime Numbers from 1 to 100 using While Loop
We just replaced the For loop in the above Python Prime Numbers 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 madly printing prime numbers from 1 to 100, this python program allows users to enter the minimum and maximum values. Next, it prints 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 to display prime numbers from 1 to N is the 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 return Sum of Prime Numbers from 1 to 100
This program finds the prime numbers between 1 and 100. Next, it’s going to add those numbers 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
It allows the user to enter Minimum and Maximum values. Next, Python returns 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))
