Python程序来打印斐波那契序列

斐波那契数列：

斐波那契数列指定了一系列数字，在下一个数字是通过将前两个数字相加而找到的。

例如：

 
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on....

请参阅以下示例：

nterms = int(input("How many terms you want? "))
# first two terms
n1 = 0
n2 = 1
count = 2
# check if the number of terms is valid
if nterms <= 0:
   print("Plese enter a positive integer")
elif nterms == 1:
   print("Fibonacci sequence:")
   print(n1)
else:
   print("Fibonacci sequence:")
   print(n1,",",n2,end=', ')
   while count < nterms:
       nth = n1 + n2
       print(nth,end=' , ')
       # update values
       n1 = n2
       n2 = nth
       count += 1

输出：
