How to replace some words in a text with another word

I am trying to replace a word i.e "sound system" with "sound_sytem" in python using dictionary. However it's not working.

Here is my code:

dictionary = {'audio system': 'audio_system'}
def replace_word(text):
  return " ".join([dictionary.get(w,w) for w in text.split()])

text = "adding a little more to an audio system,improve the audio system to be better"

print(replace_word(text))

here is my output : 

adding a little more to an audio system,improve the audio system to be better

Try using replace():

for i in dictionary:
    text.replace(i,dictionary[i])

this just replaces the key with value.
Your code doesn't work because, split function by default splits by space and audio system is split as audio and system.

Lets do this your way, using join:

dictionary = {'audio system': 'audio_system'}
def replace_word(text):
  return [dictionary[j].join([text.split(i) for i in dictionary][0]) for j in dictionary][0]

text = "adding a little more to an audio system,improve the audio system to be better"

print(replace_word(text))
