Writing a lambda function you already know

Some function definitions are simple enough that they can be converted to a lambda function. By doing this, you write less lines of code, which is pretty awesome and will come in handy, especially when you're writing and maintaining big programs. In this exercise, you will use what you know about lambda functions to convert a function that does a simple task into a lambda function. Take a look at this function definition:

def echo_word(word1, echo):
    """Concatenate echo copies of word1."""
    words = word1 * echo
    return words

The function echo_word takes 2 parameters: a string value, word1 and an integer value, echo. It returns a string that is a concatenation of echo copies of word1. Your task is to convert this simple function into a lambda function.

Define the lambda function echo_word using the variables word1 and echo. Replicate what the original function definition for echo_word() does above.
Call echo_word() with the string argument 'hey' and the value 5, in that order. Assign the call to result.
