开始使用Python Fibonacci生成器 [英] Beginning Python fibonacci generator

问题描述

我正在尝试制作一个斐波那契数生成器，该生成器以给定的数量停止，但通常会超过该数量.我在做什么错了?

I'm trying to make a fibonacci number generator that stops at a given amount, but it usually goes past the amount. What am I doing wrong?

#Fibonacci number generator
a=0
b=1
print("Fibonacci number generator.")
stopNumber=input("How high do you want to go? If you want to go forever, put n.")
print(1)
while stopNumber=="n":
        a=a+b
        b=b+a
        print(a)
        print(b)
else:
    while int(stopNumber) > a or int(stopNumber) > b:
        a=a+b
        b=b+a
        print(a)
        print(b)

推荐答案

使用您的代码:

#Fibonacci number generator
a=0
b=1
print("Fibonacci number generator.")
stopNumber=input("How high do you want to go? If you want to go forever, put n.")
print(1)
while stopNumber=="n" or int(stopNumber) > a+b:
    a, b = b, a+b
    print(b)
