When dealing with the variable naming of Visual Basic, Python, and Java There are a few rules. When naming in Visual Basic, the name cannot exceed 255 characters in length. The name must contain a letter as the first character, and finally, the name cannot contain a; space, period, exclamation mark, dollar sign, or @, &, and # character in the name.
When naming in Python all the characters and the name must begin with a letter or underscore. No other characters can be used. Variable names are Case Sensitive, and certain words are reserved. These words cannot be used as a variable name because Python utilizes these words them for other commands. Some of these reserved words are: and, del, from, not, while, as, elif, global, or, with, assert, else, if, pass, yield, break, except, import, print, break, except, import,
 print, class, exec, in, raise, class, exec, raise, continue, finally, is, return, continue, finally, is, return, def, for, lambda and try.
Java also has variable language rules. First, a variable name must begin with a letter, underscore, or Unicode currency symbol, the initial character can be followed by any number of letters, numbers, underscore characters, and Unicode currency symbols. Also a variable name can’t contain spaces, and a query result is a type of variable, so it overwrites a local variable with the same name.
Each language has similarities regarding variable naming. None of the discussed programs allow spaces in the name. Each language contains certain characters that are not allowed in the naming scheme. None of the languages allow numbers in any of the names of the variables.
Regarding differences, Visual Basic has a maximum character length of 255 characters. Python has certain words that cannot be written in the variable name because they are reserved. Also, Java allows currency symbols whereas neither of the other
