Python Code to find the letter start with a in a sentence

Here is the code to find the words start with a in the sentence: "This is an apple tree."

st = 'This is an apple tree'

for word in st.split():
    if word[0]=='a':
        print(word)

I want to make it to function, and takes in any sentence I want, how to to that? Here is the code I came up, but is not doing what I want. 

def find_words(text):
    for word in find_words.split():
        if word[0]=='a':
            print(word)
    return find_words

find_words('This is an apple tree')

Thank you.

You can use the below code. It will provide the list of words which has a word starts with 'a'.

This is simple list comprehension with if clause. Split without argument by default splits the sentence by space and startswith method helps to filter 'a'.

sentence = 'This is an apple tree'
words = [word for word in sentence.split() if word.startswith('a')]

If you want to print the result try this:

st = 'This is an apple tree'

def find_words(text):
    for word in text.split():
        if word.startswith('a'):
            print(word)

find_words(st)

The problem is how you are defining the for loop. It should be:

for word in text.split(' '):
     ...

Just because text is the parameter in your defined function
