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.
