# Python Program to print Fibonacci Sequence up to given range.

Each number in the sequence is the sum of the two numbers that precede it. So, the sequence goes: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on.

### Python Code:

• Python Program to print Fibonacci Sequence up to given range.

```ft = 0
sd = 1
print(ft,sd,end=" ")
for i in range(2,20):    # Starting from range "2" because two numbers-
td = ft+sd
print(td,end=" ")
ft = sd
sd = td```

Output:

0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181

• Python Program to check a given number is belongs to Fibonacci series or not.

```num=int(input("Enter a number:"))
ft = 0
sd = 1
for i in range(0,num):
td = ft+sd
ft = sd
sd = td
if num == td or num == 0:
print("The given number belongs to Fibonacci series.")
break
else:
print("The given number do not belongs to Fibonacci series.")```

Output:

Enter a number: 152

The given number do not belongs to Fibonacci series.

Enter a number: 233

The given number belongs to Fibonacci series.
