I am new to python and was trying some code stuff and erroneously found this. I am not able to understand the behaviour of code? what is causing infinite loop ?

any_list=[""]
 
for x in any_list:

   any_list.append("something")

CodePudding user response：

It's because you are looping and adding an item to the any_list at the same time. So it goes on forever.

CodePudding user response：

You are adding a new item to the list each iteration, thus causing the length of any_list to increase, which extends the loop.
