Python – How to take a user sentence and create a list of words out of it

listpython

I'm unsure what the user will enter but I want to break their input sentence up into words in a list

User_input = raw_input("Please enter a search criterion: ")
User_Input_list[""]

# input example: steve at the office

# compiling the regular expression:
keyword = re.compile(r"\b[aA-zZ]\b")
     for word in User_input:
         User_Input_list.append(word?)

# going by thin put example input I'd want
# User_Input_list["steve", "at" , "the" , "office"] 

I'm unsure how to split the input up into separate words? I will give cookies for help!

Best Solution

User_Input_list = User_input.split()
