[New-bugs-announce] [issue36741] Variable about function and list

[張晨韜]

New submission from 張晨韜 <s104213013 at mail1.ncnu.edu.tw>:

Hello,I'm a Taiwanese student.
First,I will say sorry because of my poor English.If I have an offense,please forgive me.
Then,look at the picture about program.I declare a list "cards" to the function "Flush",and divide them by 13 in the function.The function Flash will return boolean finally. After that,I write "main" which declare a list and call "Flush" for it to show what value it is.However,when I print this list again,its value will be changed.
I'm confused that isn't Flush.cards a local variable belong to Flush? Why Flush can change the list's value for the other function without return? I asked my friend and he was confused,too.So I send this issue and hope to know why it is.Thanks.
