How can I loop till certain range inside the list?

I have a list of 5000 words.

words=['asd','bsd',.........,'dbn']

I am trying to make the possible combinations of the words

comb = combinations(words,2)
for i in list(comb): 
  b=''.join(i)
  print(b)

How can I run the loop for the first 100 words combinations?

You can use islice and combinations from the itertools module. The following will display the first 100 combinations of length 2:

from itertools import combinations, islice

for c in islice(combinations(words, 2), 100):
    print(c)

Note that both functions return lazy generators, so that not all combinations have to be generated first (which is what happens once you call list(comb...)).

There is this great module called itertools, which most probably has what you need. Example from the permutations function:

# permutations('ABCD', 2) --> AB AC AD BA BC BD CA CB CD DA DB DC
# permutations(range(3)) --> 012 021 102 120 201 210
