python: problem with dictionary get method default value
- by goutham
I'm having a new problem here ..
CODE 1:
try:
urlParams += "%s=%s&"%(val['name'], data.get(val['name'], serverInfo_D.get(val['name'])))
except KeyError:
print "expected parameter not provided - "+val["name"]+" is missing"
exit(0)
CODE 2:
try:
urlParams += "%s=%s&"%(val['name'], data.get(val['name'], serverInfo_D[val['name']]))
except KeyError:
print "expected parameter not provided - "+val["name"]+" is missing"
exit(0)
see the diffrence in serverInfo_D[val['name']] & serverInfo_D.get(val['name'])
code 2 fails but code 1 works
the data
serverInfo_D:{'user': 'usr', 'pass': 'pass'}
data: {'par1': 9995, 'extraparam1': 22}
val: {'par1','user','pass','extraparam1'}
exception are raised for for data dict .. and all code in for loop which iterates over val
