rules for python syntax

Variable names and identifier are similar to those in many other languages :

• They start with a letter (A_Z or a-z) or underscore “_””.

• They are followed by letters, numbers or underscores.

• They are case-sensitive.

• A string is a sequence of caracters enclosed by a matching pair of single or double quotes.

Unlike python, the name’s length for concept are limited by Eficas to 8 characters.

Some identifiers are reserved words :

• You can’t use words of the python language as identifiers.

• Eficas itself uses identifiers which become reserved words. for example you can’t use the following word, even if it would make some interesting names:

  • BLOC, EXCLUS, OPER, ASSD,

  • EVAL, FACT, FORM, JDC,

  • REGLE, VALIDATOR,

  • ETAPE, ENTITE

Python’s way for assigning values to variables :

• Keep in mind that .comm are python files. The simplest form of assignement is : variable = value

• The hash character (#) starts a comment

• Tuples are enclosed in parentheses.

• Lists are enclosed in bracked.

• In tuples or lists, a ‘,’ follows each item especially the last one.
