Variable names may not be a reserved word in Python. Following the rules above, all of these variable assignments are legal: >>> fish = 11 >>> a = 12 >>> _wow_ = 13 >>> a1 = 14 >>> something_longer_is_fine_2 = 15 >>> RemoteAddress = '10.20.30.40' All the above variable names are acceptable. But just because they are acceptable does not mean you should use them. The Python community has further developed naming conventions which should be followed. For example, even though a single-character identifier is perfectly legal, you are strongly discouraged from using the characters l (lower case el) or O (uppercase oh) or I (uppercase eye).
