Make function definition in a python file order independent
python
Solution
All functions must be defined before any are used.
However, the functions can be defined in any order, as long as all are defined before any executable code uses a function.
You don't need "forward declaration" because all declarations are completely independent of each other. As long as all declarations come before all executable code.
Are you having a problem? If so, please post the code that doesn't work.
In your example, `print_something()` is out of place.
The rule: All functions must be defined before any code that does real work
Therefore, put all the statements that do work last.
Problem
I use Python CGI. I cannot call a function before it is defined. In Oracle PL/SQL there was this trick of "forward declaration": naming all the functions on top so the order of defining doesn't matter. Is there such a trick in Python as well? example: ``` def do_something(ds_parameter): helper_function(ds_parameter) .... def helper_function(hf_parameter): .... def main(): do_something(my_value) main() ``` David is right, my example is wrong. What about: ``` <start of cgi-script> def do_something(ds_parameter): helper_function(ds_parameter) .... def print_something(): do_something(my_value) print_something() def helper_function(hf_parameter): .... def main() .... main() ``` Can I "forward declare" the functions at the top of the script?
