python - 返回值后，在 main func 中的值已更改

Question

我尝试了与订阅一起使用的编写函数。当我打印价值时，我得到了我的期望，但是当我返回价值时，我得到了其他东西。我在我的输出中添加链接。当我在函数中打印时，我在返回主脚本后得到了我的期望，我得到了其他值。

输出是：

/cad/workSpaces/EDISON_cadm/.cad
poooo
f-----  1       - - - ./.cad/runsets/pvs/t.00_00_01_scr/RCE_TS18SL_QRC_3M1T3_USG/EAD/1/setup/TSL_0.18_3M1T3_USG_setup.ini
None
