关于斐波那契序列生成器的问题-没有打印

Question

我在课堂上被分配了一个任务，我需要编写一个可以生成"n"个Fibonacci序列数的算法。我觉得这段代码应该可以工作，但我仍然很难找到阻止它工作的错误。该算法应该从数字2开始打印斐波那契序列(前3个数字被补上(，但它只打印前3个数，而我的算法不打印任何内容。我甚至有复杂的错误检查，可以排除坏值，但它也没有报告任何内容。

if expression.match(str(int3)):     # if it doesn't match

zints.int4= zints.int4+1        #int4 is int4 plus 1
loop(hwmny,int1,int2,zints.int3,zints.int4,zints.errcnt)
continue
loop(hwmny,int1,int2,zints.int3,zints.int4,zints.errcnt)

Answer 1

此修复看起来很简单。while循环中的分组是错误的，将其更改为以下内容，它应该可以正常工作：

while((zints.int4<hwmny)or not(zints.int4>0)and not(zints.int4==0)):
