How does Python use a variable as the function name?

How does Python use a variable as the function name? PHP has variable function usage (see http://www.php.net/manual/en/functions.variable-functions.php)

There is a string variable

Now we want to use the value of this variable as a function name to call

The code is as follows:

Def bar (): return 'bar' foo = 'bar' foo () # here you want to call bar ()

I wonder if Python has such usage?

Haha, python is so powerful, and python can certainly support it.

Python has an eval function (which seems to be available in many languages) to solve this problem.

The code is as follows:

Def foo (): print 'hi' t = eval ('Foo') t ()

Question 2: Can python import a module with a variable value?

Foo = 'bar' import foo # here you want to import bar

Another function is used in this place...

Code:

M = 'sys 'exec "import" + m

So OK.
