## DEV Community 👩‍💻👨‍💻 # Fibonacci Day!

Fibonacci Day is celebrated today, on November 23, because the date formation of today is 11/23 (1, 1, 2, 3), which represents the Fibonacci sequence!

Here are some simple scripts to print the Fibonacci sequence in python, java and javascript.

Python:

``````nterms = int(input("Enter the value of n: "))

n1, n2 = 0, 1
count = 0

if nterms <= 0:
elif nterms == 1:
print("Fibonacci sequence upto",nterms,":")
print(n1)
else:
print("Fibonacci sequence:")
while count < nterms:
print(n1)
nth = n1 + n2
# update values
n1 = n2
n2 = nth
count += 1
``````

Java:

``````import java.util.Scanner;

public class FibonacciSeries {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
System.out.print("Enter the value of n: ");
int n = s.nextInt();
fibonacci(n);
}
public static void fibonacci(int n) {
System.out.print("Fibonacci sequence:");
if (n == 0) {
System.out.println("0");
} else if (n == 1) {
System.out.println("0 1");
} else {
System.out.print("0 1 ");
int a = 0;
int b = 1;
for (int i = 1; i < n; i++) {
int nextNumber = a + b;
System.out.print(nextNumber + " ");
a = b;
b = nextNumber;
}
}
}
}
``````

Javascript:

``````const number = parseInt(prompt('Enter the value of n: '));
let n1 = 0, n2 = 1, nextTerm;

console.log('Fibonacci sequence:');

for (let i = 1; i <= number; i++) {
console.log(n1);
nextTerm = n1 + n2;
n1 = n2;
n2 = nextTerm;
}
``````
