en python comment fait on? (python object is not iterable)

[papoo]

je débute en python et je ne sais pas faire un truc qui doit etre simple mais sur lequel je but depuis deux jours
dans mon script une fonction get_my_measures me recupere les données d'une api.

Code : Tout sélectionner

measures = client.get_measures(limit=5)

lorsque je liste chaque objet un par un, les informations sont disponibles soit avec l'iteration 0,1 ou 2(jamais la même)

Code : Tout sélectionner

print "Your 0 date: %s " % measures[0].date
print "Your 1 date: %s " % measures[1].date
print "Your 2 date: %s " % measures[2].date

print "Your 0 measured weight: %s kg" % measures[0].weight
print "Your 1 measured weight: %s kg" % measures[1].weight
print "Your 2 measured weight: %s kg" % measures[2].weight

print "Your 0 measured fat_free_mass: %s kg" % measures[0].fat_free_mass
print "Your 1 measured fat_free_mass: %s kg" % measures[1].fat_free_mass
print "Your 2 measured fat_free_mass: %s kg" % measures[2].fat_free_mass

print "Your 0 measured fat_ratio: %s percent" % measures[0].fat_ratio
print "Your 1 measured fat_ratio: %s percent" % measures[1].fat_ratio
print "Your 2 measured fat_ratio: %s percent" % measures[2].fat_ratio

print "Your 0 measured fat_mass_weight: %s kg" % measures[0].fat_mass_weight
print "Your 1 measured fat_mass_weight: %s kg" % measures[1].fat_mass_weight
print "Your 2 measured fat_mass_weight: %s kg" % measures[2].fat_mass_weight

print "Your 0 measured heart_pulse: %s p/m" % measures[0].heart_pulse
print "Your 1 measured heart_pulse: %s p/m" % measures[1].heart_pulse
print "Your 2 measured heart_pulse: %s p/m" % measures[2].heart_pulse

cela donne comme résultat :

Code : Tout sélectionner

Your 0 date: 2017-04-24T07:08:46+00:00
Your 1 date: 2017-04-24T07:08:46+00:00
Your 2 date: 2017-04-24T07:08:46+00:00
Your 0 measured weight: None kg
Your 1 measured weight: None kg
Your 2 measured weight: 92.52 kg
Your 0 measured fat_free_mass: None kg
Your 1 measured fat_free_mass: None kg
Your 2 measured fat_free_mass: 58.93 kg
Your 0 measured fat_ratio: None percent
Your 1 measured fat_ratio: None percent
Your 2 measured fat_ratio: 27.407 percent
Your 0 measured fat_mass_weight: None kg
Your 1 measured fat_mass_weight: None kg
Your 2 measured fat_mass_weight: 18.59 kg
Your 0 measured heart_pulse: None p/m
Your 1 measured heart_pulse: 92 p/m
Your 2 measured heart_pulse: None p/m

lorsque je veux faire une boucle for pour retrouver mes petits simplement

Code : Tout sélectionner

i = 0
for weight, fat_free_mass, fat_ratio, fat_mass_weight, heart_pulse in measures[i]:
	print "Your measured weight: %s kg" % weight
	print "Your measured fat_free_mass: %s kg" % fat_free_mass
	print "Your measured fat_ratio: %s percent" % fat_ratio
	print "Your measured fat_mass_weight: %s kg" % fat_mass_weight
	print "Your measured heart_pulse: %s p/m" % heart_pulse
	i = i +1

il me retourne une erreur

Code : Tout sélectionner

TypeError: 'MeasureGroup' object is not iterable

j'ai aussi testé

Code : Tout sélectionner

for list in measures:
    for x in list:
        print x

avec le même résultat
apparemment la fonction

Code : Tout sélectionner

def get_measures(self, **kwargs):
        r = self.request('measure', 'getmeas', kwargs)
        return WithingsMeasures(r)

me retourne les arguments sous forme de dictionnaire (mais je ne sais pas quoi faire de cette information)

pourriez vous svp m'aider pour débloquer la situation ?
d'avance merci
