newbie question!

[Brian]

Hi, im new to python and have a simple question...

i want too have a list of values - say numbers of tables in a restaurant...
1,2,3,4,5. i want to associate a value with each of these numbers... eg. yes
or no. when a person books table 2, the value corresponding to 2 turns to no
[not available] etc...

what would be the best way to do this ? a little code help would help aswell
!!! - newbie

thanks,

Brian

You could use a dictionary to hold the information:
.... tables = "no"
....

>>> tables[2] = "yes"
>>> for table in tables:

.... print "%2d : %s" % (table, tables

)
....
1 : no
2 : no
3 : no
4 : no
5 : no
6 : no
7 : no
8 : no
9 : no
10 : no

usa a dictionnary, and boolean values True/False:

# initialize
tables = { 1:True, 2:True, 3:True }

# customer reserves table 2
tables[2]=False

# tables is now {1: True, 2: False, 3: True}

2 : no

That should be:

2 : yes

I was testing the code in a different computer than I typed this message
on, so I wrote it all out by hand; oops

Give n tables beginning with table 1, one could use a list initialized
as
tables = (n+1)*[True]
Then 'tables[2] = False' when booked.
But I would start with 'tables = (n+1)*[False]' so I could write
tables[2] = <booking information>
when booked rather than merely True for booked.

You can either ignore tables[0] or use it to keep a count of free
tables, in which case initialize tables[0]=n and subtract 1 for each
booking.
