Create a Python program that takes two strings as input and prints the text which is the result of a mix of the words from the strings.
"today", "tomorrow"
def mix_words(word1, word2):
 
    # Create an empty result string
    result = ""
 
    # Iterate through each letter in each word
    for i in range(max(len(word1), len(word2))):
        # Check if the letter exists in both words
        if i < len(word1):
            result += word1[i]
        if i < len(word2):
            result += word2[i]
    return result
