Search element in list and print property element

Question

How to implement a search item in the worksheet with the properties of the subsequent withdrawal?

O213YB = '1111  2222'
    B443TH = '3333  4444'
    DATA = ['O211YB','B896PM','B897PM','O209YB','X899HK','B805TH','A758KP']
    nomer = input('input name ->')
if nomer in DATA:

It is not very clear what you need it to do. Could you explain a bit more? — Jorick Spitzen, May 20 '15 at 08:30
It creates a binding machine to the number of logins and passwords. Also creates a sheet with a list of numbers. It is necessary that the user enters the number of the machine and print out his login and password — Дмитрий Инкогнито, May 20 '15 at 08:34
So `DATA` holds the logins, and then the variables `O213YB` and `B443TH` hold the passwords? — Jorick Spitzen, May 20 '15 at 08:38
DATA It contains variables. Variables (O213YB and B443TH) include logins and passwords — Дмитрий Инкогнито, May 20 '15 at 08:40
So that when I enter `B896PM`, I get the value of variable `B896PM`? — Jorick Spitzen, May 20 '15 at 08:44
Yes, the program must check whether such a machine in the DATA and display its value — Дмитрий Инкогнито, May 20 '15 at 08:46

Okay, so from your comments I figured out what you want the program to do.

You could get the value using the global variable as follows:

if nomer in DATA:
    print(globals()[nomer])

For more info on that, see this post.

However, I would strongly recommend you restructure your data to a dict. Your code would then look like this:

data = {
    'O211YB': '1111 2222',
    'B896PM': '3333 4444',
    # Etcetera
}
if nomer in data.keys():
    print( data[nomer] )

So what I understood from your comments that what you want is get values of each variable referenced by its name as a string in DATA ..

In that case all you need is eval():

for x in DATA:
    print eval(x)

[**Do not ever use `eval` (or `exec`) on data that could possibly come from outside the program in any form. It is a critical security risk. You allow the author of the data to run arbitrary code on your computer.**](https://stackoverflow.com/questions/1832940/why-is-using-eval-a-bad-practice) – Karl Knechtel Jul 05 '22 at 02:02
