In this case, there is no great advantage in making swap a function, In fact, there is a danger in trying to encapsulate swap, which is the following tempting mistake:,You can use multiple except blocks to handle different kinds of exceptions (see the Errors and Exceptions lesson from Python creator Guido van Rossum’s Python Tutorial for a more complete discussion of exceptions)

Example_snippet/controller/utility/_generator.js/ >>> tup = 2, 4, 6, 8, 10 . . .
>>> tup = 2, 4, 6, 8, 10

Update: Jonathan Slenders suggested using a recursive generator to flatten the sequence of nodes, then summing the flat sequence:,Here we can see the two function calls that use the two frames: _comprehension() and then value(),,Comprehensions do this so that the variables set in the comprehension don’t leak out into the surrounding code

Example_snippet/controller/utility/_generator.js/ class Leaf:    def __init__(se. . .
class Leaf: def __init__(self): self.val = 0 # will have a value.def value(self): return self.valclass Node: def __init__(self): self.children = [] # will have nodes added to it.def value(self): return sum(c.value() for c in self.children)

Yes, there is a way to use recursions in python without stack overflow, Put below snippet in your code and then put @bootstrap over recursive function

Example_snippet/controller/utility/_generator.js/ from types import GeneratorTyp. . .
from types
import GeneratorType
def bootstrap(f, stack = []):
   def wrappedfunc( * args, ** kwargs):
   if stack:
   return f( * args, ** kwargs)
else :
   to = f( * args, ** kwargs)
while True:
   if type(to) is GeneratorType:
   stack.append(to)
to = next(to)
else :
   stack.pop()
if not stack:
   break
to = stack[-1].send(to)
return to
return wrappedfunc

The Python Call Stack,Going deeper under the hood: every time a function is called you add a stackframe (aka activation records) to the stack, The stackframe keeps track of what has been executed and what comes next

Example_snippet/controller/utility/_error.js/ def parrot(): print("parro. . .
def parrot():
   print("parrot start")
print("parrot end")

def cheese():
   print("cheese start")
parrot()
print("cheese end")

cheese()

A RecursionOverflow exception will be raised when a call to a Python function causes the recursion limit to be exceeded, This is a slight change from current behavior which raises a RecursionError

Example_snippet/controller/utility/_error.js/ sys.setrecursionlimit(1_000_00. . .
sys.setrecursionlimit(1_000_000)

def f(n):
   if n:
   f(n - 1)

f(500_000)
load more v
