Hello!!

Answer:

Plastic extrusion is the process through which plastic is heated and forced through a heated chamber by a screw.

Molding is the process of forcing plastic through a die to form the final shape of a product.

Cooling: The plastic extruded is chilled.

Spool or cut: The continuous form is either spooled or cut into lengths.

Mold construction: Small plastic pellets are melted and moulded into a hollow tube known as a parison or preform (depending on the blow molding subtype).

Molding: The parison is clamped into a mold and inflated with pressured air until it adopts the shape of the mold's interior.

Cooling and ejection: The item cools in the mold until it is firm enough to be expelled.

Lesechka [4]

Answer:

See explaination for the code

Explanation:

def wordsOfFrequency(words, freq):

d = {}

res = []

for i in range(len(words)):

if(words[i].lower() in d):

d[words[i].lower()] = d[words[i].lower()] + 1

else:

d[words[i].lower()] = 1

for word in words:

if d[word.lower()]==freq:

res.append(word)

return res

Note:

First a dictionary is created to keep the count of the lowercase form of each word.

Then, using another for loop, each word count is matched with the freq, if it matches, the word is appended to the result list res.

Finally the res list is appended.
