[HELP] Nested conditional? double condition followed by another condition.

[penahuse]

Im trying to learn python but struggling on this problem. I will be thankfull if anyone give me some help.

1 2 3 4 5 6

while button1_pressed and button2_pressed: #no matter which one is pressed first to me     do some     while button3_pressed: #only if it is pressed after button1 and button2 are pressed         do some2         if button2_is_not_pressed:             break

in practice "do some2" activates even when I press button 3 before buttons 1 and 2. Anyone can help me, please?

button1_pressed and button2_pressed must both be True before you press button 3.

[penahuse]

button1_pressed and button2_pressed must both be True before you press button 3.

Thank you for your answer but i do not fully understand. English isnt my first language.

The button1_pressed, button2_pressed and button3_pressed are functions. I forgot to mention that.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

def button1_pressed():  # Returns true if the left mouse button is pressed     button1_state = win32api.GetKeyState(0x01)     return button1_state < 0   def button2_pressed():  # Returns true if the right mouse button is pressed     button2_state = win32api.GetKeyState(0x02)     return  button2_state < 0   def button3_pressed():  # Returns true if the M button is pressed     button3_state = win32api.GetKeyState(0x4D)     return button3_state < 0   while button1_pressed() and button2_pressed(): # No matter which one is pressed first to me     do some     while button3_pressed(): # Only if it is pressed after button1 and button2 are pressed         do some2         if button2_pressed() == 0:             break

The problem is: if I press button3_pressed even before button1_pressed and button2_pressed do some2 activate. I do not want this..

1 2 3 4 5 6 7 8 9 10 11 12

button1_pressed = True button2_pressed = True button3_pressed = True button2_is_not_pressed = True   while button1_pressed and button2_pressed:     print('do some') # this only happens if both the above are True     while button3_pressed:         print('do some2') #  theis only happens if button3_pressed is True         if button2_is_not_pressed:             break # this only breaks the inner while loop     break # added an extra break else it would just be stuck in an endless outer loop

Output:
do some
do some2

The following conditions nothing will happen

1 2 3 4 5 6 7 8 9 10 11 12

button1_pressed = False button2_pressed = True button3_pressed = True button2_is_not_pressed = True   while button1_pressed and button2_pressed:     print('do some') # this only happens if both the above are True     while button3_pressed:         print('do some2') #  theis only happens if button3_pressed is True         if button2_is_not_pressed:             break # this only breaks the inner while loop     break # added an extra break else it would just be stuck in an endless loop

Output:

button1_pressed and button2_pressed must be returning True even though you think they should not be.

I really apreciate your help... but imagine this situation:

1 - user press button1 and button2 then press button3
Its ok to me "do some 2"
2 - user press button2 and button1 then press button3
Its ok to me "do some 2"

but

3 - user press button3 before button1 and button2
Its not ok to "do some2", I need just to "do some"

Mate, I should have mentioned that this whole code is inside a Main loop. Im sorry!!

So.. I Thinks to test should be like this:

1 2 3 4 5 6 7 8 9 10 11 12 13

button1_pressed = True button2_pressed = True button3_pressed = True button2_is_not_pressed = True   while True:     while button1_pressed and button2_pressed:         print('do some') # this only happens if both the above are True         while button3_pressed:             print('do some2') #  theis only happens if button3_pressed is True             if button2_is_not_pressed:                 break # this only breaks the inner while loop         break # added an extra break else it would just be stuck in an endless outer loop

In your function, you get the state of the button press. It can be an integer between 1 and 0 (pressed or not pressed).
When you return it, to get a True or False output you check if it is less than 0.

When the key isn't pressed, button_state is going to be 0:
0 < 0 = True.
Meaning when the button isn't pressed the while loop can still run. Surely you would want something like this:

1	return bool(button1_state)

Since bool(0) returns False, and bool(1) returns True.

Am I missing something here?

Thank you for your answer.

I made some mistakes editing the posts..

Could you give a look a it:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

def button1_pressed():  # Returns true if the left mouse button is pressed     button1_state = win32api.GetKeyState(0x01)     return button1_state < 0    def button2_pressed():  # Returns true if the right mouse button is pressed     button2_state = win32api.GetKeyState(0x02)     return  button2_state < 0    def button3_pressed():  # Returns true if the M button is pressed     button3_state = win32api.GetKeyState(0x4D)     return button3_state < 0    while True:     while button1_pressed() and button2_pressed(): # No matter which one is pressed first to me         print("do some")         while button3_pressed(): # Only if it is pressed after button1 and button2 are pressed             print("do some2")             if button2_pressed() == 0:                 break # this only breaks the inner while loop         break # added an extra break else it would just be stuck in an endless loop

Try this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

def button1_pressed():  # Returns true if the left mouse button is pressed     button1_state = win32api.GetKeyState(0x01)     return bool(button1_state)     def button2_pressed():  # Returns true if the right mouse button is pressed     button2_state = win32api.GetKeyState(0x02)     return  bool(button2_state)     def button3_pressed():  # Returns true if the M button is pressed     button3_state = win32api.GetKeyState(0x4D)     return bool(button3_state)     while True:     while button1_pressed() and button2_pressed(): # No matter which one is pressed first to me         print("do some")         while button3_pressed(): # Only if it is pressed after button1 and button2 are pressed             print("do some2")             if button2_pressed() == 0:                 break # this only breaks the inner while loop         break # added an extra break else it would just be stuck in an endless loop

Did not work well. Printed infinite "do some" until I click again any mouse button again (to return False) but I need it to work only if the buttons are pressed at same time.

I apreciate your try anyway!

I did some testing. If you use 'GetAsyncKeyState' it should work. 'GetAsyncKeyState' is basically 'isKeyPressed' so the moment you let go of a button, it will no longer return true.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

def button1_pressed():  # Returns true if the left mouse button is pressed     button1_state = win32api.GetAsyncKeyState(0x01)     return bool(button1_state)      def button2_pressed():  # Returns true if the right mouse button is pressed     button2_state = win32api.GetAsyncKeyState(0x02)     return  bool(button2_state)      def button3_pressed():  # Returns true if the M button is pressed     button3_state = win32api.GetAsyncKeyState(0x4D)     return bool(button3_state)      while True:     while button1_pressed() and button2_pressed(): # No matter which one is pressed first to me         print("do some")         while button3_pressed(): # Only if it is pressed after button1 and button2 are pressed             print("do some2")             if button2_pressed() == 0:                 break # this only breaks the inner while loop         break # added an extra break else it would just be stuck in an endless loop
