Answers for "combinations python"

combination python

# 1. Print all combinations 
from itertools import combinations

comb = combinations([1, 1, 3], 2)
print(list(combinations([1, 2, 3], 2)))
# Output: [(1, 2), (1, 3), (2, 3)]

# 2. Counting combinations
from math import comb
print(comb(10,3))
#Output: 120

how to get all possible combinations in python

all_combinations = [list(zip(each_permutation, list2)) for each_permutation in itertools.permutations(list1, len(list2))]

Python Combinations

# A Python program to print all
# permutations using library function
from itertools import permutations
 
# Get all permutations of [1, 2, 3]
perm = permutations([1, 2, 3])
 
# Print the obtained permutations
for i in list(perm):
    print (i)

python combinations

import itertools
def subs(l):
    res = []
    for i in range(1, len(l) + 1):
        for combo in itertools.combinations(l, i):
            res.append(list(combo))
    return res

python combinations function

def combinations(iterable, r):
    pool = tuple(iterable)
    n = len(pool)
    for indices in permutations(range(n), r):
        if sorted(indices) == list(indices):
            yield tuple(pool[i] for i in indices)

python create a program that runs through all possible combinations

from itertools import combinations

lst = ["a" ,"b", "c"]
lengthOfStrings = 3
for i in combinations(lst, lengthOfStrings):
  print(i)
