python - for loop iterate tuples -


i'm beginner in python (and going coding after 20 years...)

i'm doing small script in order learn irregular english verbs. create dict (it's in french)

verbes = { "abide":["abode","abode","respecter / se conformer à"], "arise":["arisen","arisen","survenir"], }

if want iterate verbes i'm doing exemple:

for verb, (pret, past, trad) in verbes.items():     print "le verbe %s se conjugue au prétérit par %s, au participe passé par %s et se traduit par %s" % (verb, pret, past, trad)

ok works. found out can import random pick 1 random key , value in dictionnary

rand = random.choice(verbes.items())

if print rand have key, value if iterate again have traceback:

traceback (most recent call last): file ".\exverbe1.py", line 209, in <module>     verb, (pret, past, trad) in rand.items(): attributeerror: 'tuple' object has no attribute 'items'

i'm not yet @ "tuple" lesson i've tried turn list, dict, etc. without success. looked on "for loop tuple" in stackoverflow without result. i'm asking after 3 hours trying figure out...

random.choice(verbes.items()) picks 1 tuple @ random verbes.items(). rand therefore contains 1 item - rand[0] holds key , rand[1] value.

if you're trying iterate on items in value list:

for val in rand[1]:   print val

to unpack rand tuple constituents:

verb, (pret, past, trad)

verb contains key, , pret, past , trad each element in list corresponding key.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
