Make function definition in a python file order independant
<p>I use Python CGI.  I cannot call a function before it is defined.</p>

<p>In Oracle PL/SQL there was this trick of "forward declaration"; naming all the functions on top so the order of defining didn't matter no more.</p>

<p>Is there such a trick in Python as well?</p>

<p>example:</p>

<pre><code>def do_something(ds_parameter):
    helper_function(ds_parameter)
    ....

def helper_function(hf_parameter):
    ....

def main():
    do_something(my_value)

main()
</code></pre>

<p>David is right, my example is wrong.
What about:</p>

<pre><code>&lt;start of cgi-script&gt;

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()
</code></pre>

<p>Can I "forward declare" the functions at the top of the script? </p>
