I$\text{'}$m stuck on creating the next$\_$combination method in Python using the attached algorithm. Could someone please help with translating this into Python code?

import collections

class Combination:

def $\_\_$init$\_\_($self$,$ values, subset$\_$len$)$:

set$\_$values $=$ sorted$($set$($values$))$

self.combination$\_$set $=$ list$($set$\_$values$)$

self.subset$\_$length $=$ subset$\_$len

self.current$\_$combination $=$ list$($self$.$combination$\_$set$[$:subset$\_$len$])$

def reset$\_$combination$($self$)$:

self.current$\_$combination $=$ list$($self$.$combination$\_$set$[$:self.subset$\_$length$])$

def get$\_$combination$($self$)$:

return list$($self$.$current$\_$combination$)$

def set$\_$combination$($self$,$ combo$)$:

set$\_$combo $=$ sorted$($set$($combo$))$

if len$($set$\_$combo$)!=$ self.subset$\_$length:

return

for value in set$\_$combo:

if value not in self.combination$\_$set:

return

self.current$\_$combination $=$ list$($combo$)$

def print$\_$all$\_$combinations$($self$)$:

#TODO: Make sure you start at the beginning $($see the

# reset$\_$combination method$)$

#TODO: Print combination

#TODO: Generate a next Combination

#TODO: Repeat $($It helps if your next$\_$combination method returns a boolean$)$

self.reset$\_$combination$()$

while True:

print$($self$.$current$\_$combination$)$

if not self.next$\_$combination$()$:

break

def next$\_$combination$($self$)$:

#TODO: Move from right to left in both the

# currentCombination and the combinationSet

# until the numbers do not match. $($Hint$,$ use negative indexing$)$

#TODO: Find startPos as $1$ plus the position of the

# number from the current combination that did

# not match in the combinationSet. Fill in

# from left to right in the currentCombination

# starting at the position of the mismatch the

# numbers from the combinationSet starting at

# the startPos you just found

#TODO: If there was no mismatch start combination over at the

# first subset. $($see the reset$\_$combination method$).$

# It is helpful to return a boolean indicating if the combination has been reset.
