[Tutor] Reference a variable from a string whose value is the name of the variable

[Patrick Wheeler]

>data = [ ]
>for i in xrange(1,101):
> data = data.append((f %i  _n, f %i_v))

The function locals() will return a dictionary of variables in the current
scope.  This can then be used to reference variables by name.
x=1
xname = 'x'
print locals()['x']
print locals()[xname]
This prints:
1
1

or for your example.
data = [ ]
for i in xrange(1,101):
    data = data.append
((locals()['f'+str(i)+'_n'],locals()['f'+str(i)+'_v']{}))

Hope this helps.
