A variable falls under the category of "Python identifier". SUch an identifier must start with a letter (uppercase or lowercase) or an underscore, followed by zero or more letters, underscores, and digits. Note that Python is case-sensitive; for example, myvariable, MyVariable, and MYVARIABLE would be treated as three different variables.
There are no strict rules. Sometimes the first letter of the object represented by the variable is used eg m for mass, v for velocity. At other times, they are sequential letters of the alphabet, such as a, b, c or x, y, z. The variables may be letters from the Greek alphabet; they may be in upper case or lower case.
It is advisable not to use names which may be confused with numbers (depending on your handwriting). For various numbers, possible letters which may cash are:
0 and O
1 and I (upper case i) or l (lower case L)
2 and z
5 and S
6 and b
8 and B
9 and g (not very similar here but consider the letter as it is "normally" written.

Rules in naming variables in programming?
there are various types of naming rule provide for function ,identifier,i.e variables.but naming rule for variable must meet certain condition.. 1.you can easily idenfy what is variable for.for eg.you may use int a;/to store no of student in your prog. but it is better instead of using "a",you can write any of the following definition int stu; or int stu_no; or int studentno; 2.it must be abbreviated.because although modern compiler support 32 char variable but still where you use that variable you have to type that name again &again. so for eg. in the above case int stu_no; is optimal. when these precondition are met then here are some rules for naming a variable: 1.you use only English alphabet,numeric no,& _(underscore). 2.you must start with a alphabet. then you continue with alphabet or numeric or under score.for eg. you can define a variable like int stu_comp_2009;//for no of student 2009 batch. 3.no variable can start with number or _.such naming may cause some compiler do the right job but maximum would not support this.
