In this particular case I would say there is no difference
I guess what bothers you is the use of lambda. Basically that is anonymous function

it's the same to have separate function

def lowercase_email(email):
    return email.lower()

...
df['Email'] = df['Email'].apply(lowercase_email)

look at pandas.Series.apply
