Fibonacci Sequence in Python

#Program to display the Fibonacci sequence up to n-th term where n is provided by the user
# change this value for a different result
nterms = 10
# uncomment to take input from the user
#nterms = int(input("How many terms? "))
# first two terms
n1 = 0
n2 = 1
count = 0
# check if the number of terms is valid
if nterms <= 0:

print("Please enter a positive integer")

elif nterms == 1:

print("Fibonacci sequence upto",nterms,":")
print(n1)

else:

print("Fibonacci sequence upto",nterms,":")
while count < nterms:

print(n1,end=' , ')
nth = n1 + n2
# update values
n1 = n2
n2 = nth
count += 1

Output:

Fibonacci sequence upto 10 :
0, 1, 1, 2, 3, 5, 8, 13, 21, 34,
