This looks like a honework assignment... if thats the case, please keep in mind that if u dont understand the basics and u dont try to understand it, you will never learn it... also, SO is here to help u with your problem, when u get stuck by getting somekinda error or something... right now all u did is nothing and u r just crying for help... but I have a good more, so here is the code that does it (u should know how to ha dle input;))

inp = "Bla bla bla bla tra tra tea"
inp2 = "r"
words = inp.split(" ")
for w in words:
    if inp2 in w:
        print(w)

Also u need to fix formatting (this eill print each word to a different line;)... if u have any other questions, please let me know:)

It seems like you want to print all words that contain a specific letter. Just split the string on the spaces then either remove all the words that don't have the char or add those that do to a new list then join the list on a space to recombine it. This approach does assume there is are spaces between each word not tabs or newlines (you can just remove the ' ' from the split to split on whitespace but this approach always reassembles the good words using single spaces.

words = line.split(' ')
goodWords = []
for word in words:
    if word.find(keyChar) != -1:
        goodWords.append(word)
goodLine = ' '.join(goodWords)

Just use the.split function, it will split each individual word up into an array list so that you can individually assess each word.
