search_words = ["red", "brown"]

# Open a file for read
file=open(r'test.txt','r')

# Read each line in file
for line in file

   #Search each line
   for words in search_words:
      if words in line:
          print words

file.close()


* create a list containing search words
* open file for reading
* iterate through each line in the text file
* iterate though each word in search words
* check if the line contains the word your searching for
* print the word if it does
* close file
