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
