我想在openpyxl中使用double for循环

Question

我正在制定一个按年份和季度组织收入的程序。

new ArrayList<>()

---------------------------------问题代码------------ --------------------------

retyear() list type, Source file data  with information of year = [2009, 2017, 2019, ,2020, 2021, 2022, 2099]
shtcount=len(retyear)
shtcount2=(len(retyear)*5)

• code : print(retyear[p]) -> Works Fine!
• code : double for loop -> Work Strangely...

double for循环仅提取数字2099 ...为什么？
