Is there anything in Python which is equivalent to "$$" in PHP

[3togo]

I am very new to python and would like to ask whether there is anything equivalent in python that could work like "$$" in PHP.

Many thanks.

<?php
error_reporting(E_ALL);

$name = "Christine_Nothdurfter";
// not Christine Nothdurfter
// you are not allowed to leave a space inside a variable name ;)
$$name = "'s students of Tyrolean language ";

print " $name{$$name}<br>";
print "$name$Christine_Nothdurfter";
// same
?>

for those of us that know python, but not php, what does the $$ do?

edit:
are you dereferencing a variable to get the name of another variable? if so,
>>> s='x'
>>> exec s+"=3"
>>> print x
3

No, the $$ is creating a variable from the value of another. Meaning:



<?php
$var = "testo";

$$var = "I like pudding.";

echo $testo; // Prints "I like pudding" to the screen
?>


I don't know python, but to the OP: Please don't do this unless you have a very good reason and you document it well. Supporting code like that is a nightmare.

Hmm.. I don't know if I'm doing good posting an answer to this, there are ways to avoid what you want. But..



var = "testo"
exec("%s = '%s'" % (var, "I like pudding"))
print testo


Somewhat trickie, but does what you want

thats probably not a great style to code in.can you trust that $var is not the name of a variable you are already using?

see if you can solve the problem using dictionaries.



var = "testo"
my_dict = {} # make an empty dictionary
my_dict[var] = "I like pudding"
print my_dict["testo"]
