print (5 + 2 == 7 and 10 <= 1232 and 100 ^ 1000 >= 128) # Incorrect 

  Output: True

This argument should be false but it prints true. This is the logical error vulnerability. Try this code in another language too. You find out they print false because the argument is false but unfortunately Python prints true. Because Python does not understand this.

This appears to be similar to issue42488, which it looks like you also reported, with a different account.

It's not clear to me why you expect the output to be False. But in any event, this is not a bug in Python.

>>> 100 ^ 1000
908

Please do not create issues on the bug tracker without doing some research. You're wasting volunteer's time.

Please do not talk like behave properly. I know here I am wrong but it is not way to talk to some one like that. I respect your knowledge but maintain your language. Okay! 

I send you new file with full research. Please check it out and thank you

Look tell why you close this
 

In the argument:
print (5 + 2 == 7 and 10 <= 1232 != 10 ^ 100 <= 100)

10 <= 1232 != 10 ^ 100 <= 100

10 <= 1232 is true
10 ^ 100 <= 100 is false

These two argument compares by != 
So, this statement must be true. 

Overall: print (5 + 2 == 7 and 10 <= 1232 != 10 ^ 100 <= 100)

This is the argument is true but is print false.

You need to learn about chained comparisons in Python. This is not a bug. Please stop reopening it.
