How to merge all of the output lists into one list [closed]

I was trying the following code snippet for a project of mine:

scrap=['Theodore von Kármán Lecture', 'Science Journey: "The Origin of Photosynthesis: A Window into the Intricate Relationship Between Life and the World Around It"', 'Science Journey: "Addressing Energy Storage Challenges: Making Electrolytes That Can Help Batteries Store More Energy"', 'Science Journey: "Defects in Crystals: The Tiniest Engineering Tool"']

for i in scrap:
    words_in_scrap = i.split() 
    # print("words_in_scrap=",words_in_scrap) 
    for j in words_in_scrap:
      words = j.lower()
      # print(words)
      for k in words: 
        # print(k)
        if k in punc:
          words = words.replace(k,"")
          # print(words)
      # print(k)
      clean = words      #corrected lot
      # print(clean)
      c_list = []
      c_list.append(clean)
      print(c_list)

I got this output:

['theodore']
['von']
['kármán']
['lecture']
['science']
['journey']
['the']
['origin']
['of']
['photosynthesis']
['a']
['window']
['into']
['the']
['intricate']
['relationship']
['between']
['life']
['and']
['the']
['world']
['around']
['it']
['science']
['journey']
['addressing']
['energy']
['storage']
['challenges']
['making']
['electrolytes']
['that']
['can']
['help']
['batteries']
['store']
['more']
['energy']
['science']
['journey']
['defects']
['in']
['crystals']
['the']
['tiniest']
['engineering']
['tool']

I want all of these output lists to be put into one list, like:

[‘theodore’,’von’,’karman’,’science’,………….]

I understand that these individual outputs were produced due to loops, I’ve tried to do .append() for doing this and ended up with the c_list and they turned out to be independent lists. Any solution to this will be highly valued and appreciated. Thanks!

scrap=['Theodore von Kármán Lecture', 'Science Journey: "The Origin of Photosynthesis: A Window into the Intricate Relationship Between Life and the World Around It"', 'Science Journey: "Addressing Energy Storage Challenges: Making Electrolytes That Can Help Batteries Store More Energy"', 'Science Journey: "Defects in Crystals: The Tiniest Engineering Tool"']
punc = [".","/",":"]
c_list = []
for i in scrap:
    words_in_scrap = i.split() 
    # print("words_in_scrap=",words_in_scrap) 
    for j in words_in_scrap:
      words = j.lower()
      # print(words)
      for k in words: 
        # print(k)
        if k in punc:
          words = words.replace(k,"")
          # print(words)
      # print(k)
      clean = words      #corrected lot
      # print(clean)

      c_list.append(clean)

print(c_list)

I assumes punc is tab list of punctuation.

Is this working for you ?

output :

[‘theodore’, ‘von’, ‘kármán’, ‘lecture’, ‘science’, ‘journey:’, ‘”the’, ‘origin’, ‘of’, ‘photosynthesis:’, ‘a’, ‘window’, ‘into’, ‘the’, ‘intricate’, ‘relationship’, ‘between’, ‘life’, ‘and’, ‘the’, ‘world’, ‘around’, ‘it”‘, ‘science’, ‘journey:’, ‘”addressing’, ‘energy’, ‘storage’, ‘challenges:’, ‘making’, ‘electrolytes’, ‘that’, ‘can’, ‘help’, ‘batteries’, ‘store’, ‘more’, ‘energy”‘, ‘science’, ‘journey:’, ‘”defects’, ‘in’, ‘crystals:’, ‘the’, ‘tiniest’, ‘engineering’, ‘tool”‘]
