Print first ten digits of Fibonacci Series no.

# Python Program to Print the Fibonacci sequence

In this program, youâ€™ll learn to print the Fibonacci sequence using while loop.

To understand this example, you should have the knowledge of the following Python programming topics:

A Fibonacci sequence is the integer sequence of 0, 1, 1, 2, 3, 5, 8â€¦

The first two terms are 0 and 1. All other terms are obtained by adding the preceding two terms. This means to say the nth term is the sum of (n-1)th and (n-2)th term.

## Source Code

```
# Program to display the Fibonacci sequence up to n-th term
nterms = int(input("How many terms? "))
# first two terms
n1, n2 = 0, 1
count = 0
# check if the number of terms is valid
if nterms <= 0:
print("Please enter a positive integer")
# if there is only one term, return n1
elif nterms == 1:
print("Fibonacci sequence upto",nterms,":")
print(n1)
# generate fibonacci sequence
else:
print("Fibonacci sequence:")
while count < nterms:
print(n1)
nth = n1 + n2
# update values
n1 = n2
n2 = nth
count += 1
```

**Output**

How many terms? 7 Fibonacci sequence: 0 1 1 2 3 5 8

10 terms, already given above.

nterms = int(input(â€śhow many terms ?â€ť))

n1, n2 = 0, 1

count = 0

if nterms>=0:

print(â€śfibonacci sequenceâ€ť)

while count<nterms:

print(n1)

sum=n1+n2

n1=n2

n2=sum

count+=1

nterms = int(input(â€śhow many terms ?â€ť))

n1, n2 = 0, 1

count = 0

if nterms>=0:

print(â€śfibonacci sequenceâ€ť)

while count<nterms:

print(n1)

sum=n1+n2

n1=n2

n2=sum

count+=1

#fibonacci no. till nterms.

a=0

b=1

print(a)

print(b)

for i in range(1,9):

c=a+b

print(c)

a=b

b=c

Found a simplest code for printing nterms of Fibonacci no.

nth= int(input(â€śnth termâ€ť))

a=0

b=1

print(a)

print(b)

for i in range(1,(nth-1)):

c=a+b

print(c)

a=b

b=c
