Reducing boilerplate in string generation functions in python

If you have repetitive code that generates strings you can greatly reduce boilerplate by using the function locals(), which returns a dictionary with the current local variables in a function, and the format() method, which is the current preferred method for string formatting.

As an example, consider the following function:

def generate_address(street, number, district, city, state, zipcode):
    address = """
    {street}, {number} - {district} 
    {city} - {state}        {zipcode}
    """.format(**locals())
    return address
