"""

Write a function that when given a URL as a string, parses out just the domain name and returns it as a string.

Examples:

domain_name("http://github.com/SaadBenn") == "github"

domain_name("http://www.zombie-bites.com") == "zombie-bites"

domain_name("https://www.cnet.com") == "cnet"

Note: The idea is not to use any built-in libraries such as re (regular expression) or urlparse except .split() built-in function

"""

# Non pythonic way

def domain_name_1(url):

#grab only the non http(s) part

full_domain_name = url.split('//')[-1]

#grab the actual one depending on the len of the list

actual_domain = full_domain_name.split('.')

# case when www is in the url

if (len(actual_domain) > 2):

return actual_domain[1]

# case when www is not in the url

return actual_domain[0]

# pythonic one liner

def domain_name_2(url):

return url.split("//")[-1].split("www.")[-1].split(".")[0]
