But I would use another solution if possible.

why?

Python works better if you use it to write Python code.  the Python
solution is to use a dictionary:

key1 = toto

data = {}
data[toto] = 5

print data[key1]

Because i don't want to use this syntax because it is too long, I want a 
direct access :

Not :
DicoUser['TOTO'].DicoTable.['MY_TABLE'].DicoLabel.['MY_LABEL']  =  for 
exemple

Finally, i want to use :
TOTO.MY_TABLE.MY_LABEL = for exemple

setattr might be what you are looking for

TRy db_row does exactly what you want to do. Slower, but more simple:
##
#Sequence2Struct.py

class Struct:
pass

def MakeStruct(seq, names):
obj = Struct()
if len(seq) != len(names):
raise IndexError(seq and names are not the same length)
for i in range(len(names)):
obj.__dict__[names[i]] = seq[i]
return obj

def ExtractNames(t):
return [item[0] for item in t]


if __name__ == __main__:
t = (1, 2, 3)
n1 = ((A, 1), (B, 1), (C, 2))
n = ExtractNames(n1)
print n
s = MakeStruct(t, n)
print s, s.A, s.B, s.C
n = (A, B)
s1 = MakeStruct(t, n)
