Code to display prime numbers from 1 to 100 or 1 to n in Python

In this article, we will discuss the concept of Code to display prime numbers from 1 to 100 or 1 to n in Python

In this code, we are going to learn how to print prime number from 1 to 100 or 1 to n using several ways in Python language.

This is done using for loop , while loop and function  in Python language.

Display prime numbers from 1 to 100 or 1 to n using for loop

In this program, we will print prime numbers from 1 to 100 or 1 to n  using a for loop in Python language

Program 1

#Code to display prime numbers from 1 to 100 or 1 to n in Python
n=int(input("Enter a maximum number for n"))
for number in range(1,n+1):
  if(number>1):
    for i in range(2,number):
      if(number%i==0):
        break
    else:
        print(number)

When the above code is executed, it produces the following result

Enter a maximum number for n100

Display prime numbers from 1 to 100 or 1 to n  using while loop

In this program, we will print prime numbers from 1 to 100 or 1 to n  using a while loop in Python language

Program 2

#python program to print prime number from 1 to 100 or 1 to n
max=int(input("Please enter any number: "))
Number=1
print("prime number 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)
    Number=Number+1

When the above code is executed, it produces the following result

Please enter any number: 100
