Question

Sorry this might be a very stupid question. But I did have bug with the following naming.

for i in my_hash_dict:      #1st
   for y in my_hash_dict[i]:
      do something with i ...

for i in my_hash_dict:       #2nd
      do something with i...

the problem is seems like if I reusing i this name in 2nd for loop , it “seems” will cost my program not running correctly. If I change the i in 2nd for loop, then seems everything working fine…

Maybe it just some of my stupid typo or something else cause this problem.

But I hope experiecned python programmer can give me some answers… Thankyou

The problem is that you are using the ‘i’ element as index.
Probably this code will work for you:

for element in my_hash_dict:     
    for y in element:
        do something with y ...
