Lets take
looks on Identifiers and Operators mostly used in Python script.
Variable
names and Identifiers in Python are similar to those in many other languages
they will start with letter (A-Z or a-z) or an underscore(_). Their length is limited only by your
eagerness to type, and they are case-sensitive like kalgyan and Kalgyan are two different identifiers. Regardless of length, choose identifiers that
are meaningful.
