How do I import variable packages in Python like using variable variables ($$) in PHP? -

i want import bundle depending on value user chooses.

the default file1.py:

from files import file1

if user chooses file2, should :

from files import file2

in php, can using variable variables:

class="lang-php prettyprint-override">$file_name = 'file1'; include($$file_name); class="lang-php prettyprint-override">$file_name = 'file2'; include($$file_name);

how can in python?

python doesn't have feature that's straight equivalent php's "variable variables". "variable variable"'s value (or value of other expression) can utilize eval function.

foo = "hello world" print eval("foo")

however, can't used in import statement.

it possible utilize __import__ function import using variable.

package = "os" name = "path" imported = getattr(__import__(package, fromlist=[name]), name)

is equivalent to

from os import path imported

python variables variable-variables

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison
