print(kwlist)



#intialize test strings

string = 'This attribute returns a list of all keywords reserved for the interpreter. If any keywords are planned in future versions, they are included too.'



string_list = string.split()



#check if test strings are present in kwlist

for word in string_list:

   print(word,': ', word in kwlist)

Explanation

  • Line 2: We import the keyword module.
  • Line 5: We store the list of keywords in kwlist using keyword.kwlist.
  • Line 9: We initialize a string (paragraph) that contains keywords and non-keywords both.
  • Line 13: We split the string into a list string_list that contains all words of the string.
