The format_address function separates out parts of the address string into new strings: house_number and street_name, and returns: "house number X on street named Y". The format of the input string is: numeric house number, followed by the street name which may contain numbers, but never by themselves, and could be several words long.

function format_address separates it into two strings:

house_number and

street_name

Explanation:

For example, "123 Main Street", "1001 1st Ave", or "55 North Center Drive". Fill in the gaps to complete this function.

# Declare variables

house_number = ''

street_name = ''

# Separate the address string into parts

spi = address_string. split ()

# Traverse through the address parts

for ele in spi:

# Determine if the address part is the

# house number or part of the street name

if ele. isdigit ():

house_number = ele

else:

street_name + = ele

street_name + = ' '

# Does anything else need to be done

# before returning the result?

# Return the formatted string

return "house number {} on street named {}". format (house_number, street_name)
