How can I write Python script to combine whiles with ifs and break entire nested-loop if condition met? I have read other topics, but I cannot get script working...

How can I wrote this script to exit or break all nested-loops, when if condition is met?

Script:

breaker = False
while True:
  ...commands...
  if ... :
    ...commands...
    if ... :
      ...commands...
      while True:
        ...commands...
        if ... :
          if ... :
            breaker = True
            break # ...to exit all loops
        i  = 1
   j -= 1
if breaker:
  break

...continue script here if `break`

For each if statement you need to close it with an else each one need to have one otherwise I don't think the code will work and that last (j-=1) I think it has to be on top of the last (if breaker:) code you made.

The root cause of your problem is a bad source code design (a 'bad smell' as described in https://refactoring.guru/smells/long-method). As a rule of thumb: do not use more than one / two nested conditionals in a function (i.e. while, if, until, ...). Try to refactor your code as e.g. shown in Martin Fowler's Book (https://martinfowler.com/books/refactoring.html) or in many good tutorials (e.g. https://refactoring.guru/extract-method).

You will see that this will simplify your life - and you can use a return from a function instead of some break statement.
