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,
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.
