Before writing code for Fibonacci sequence let’s know what is Fibonacci number.

The fibonacci sequence looks like 0 1 1 2 3 5 8 13 21 ….

The Fibonacci sequence is a set of numbers that starts with zero followed by one. And each number is equal to the sum of the preceding two numbers.

Example:

**Step 1:**

1st number=0

2nd number=1

Here term is 2

Then next number will be sum of 1st number & 2nd number.That is 1

**Step 2:**

Now the sequence became

0 1 1

Here term is 3

Next number = 1 + 1 = 2

**Step 3: **

New sequence is 0 1 1 2

Here term is 4

Next number = 1 +2 = 3

So new sequence became

0 1 1 2 3

As you can see every number is equal to sum of 2 previous number

**Code:** Now Write below lines of code for Fibonacci series

#take input from the user term=int(input("Enter term: ")) num1 = 0 num2 = 1 count = 0while count < term: print(num1) nth = num1 + num2 num1 = num2 num2 = nth count += 1

**Output 1:**

enter term : 5

0

1

1

2

3

**Output 2:**

enter term :10

0

1

1

2

3

5

8

13

21

Good post. I learn something new and challenging on websites I stumbleupon everyday.

It’s always useful to read through articles from

other authors and use a little something from their web sites.
