I am writing a function to find correct transformer lamination for
specific wattage. It gives an error message:
UnboundLocalError: local variable 'stdArea' referenced before assignment
def power2lam():
voltAmp=raw_input("How much power in Watts you want to handle?:
")
#following dictionary is for finding the correct lamination size
practically available.
dictLam={0.2:32,2:17,5:12,6:1,7:74,10:2,18:45,31:15,45:33,75:13,156:5,494:43}
temp=dictLam.keys()
temp.sort()
vamaxList=temp
print vamaxList
for x in vamaxList:
if x<voltAmp:
pass#print ".",
else:
stdArea=(math.sqrt(x))/6
print x
break #break is needed to prevent further checks
in the dict
windArea=(math.sqrt(stdArea))*0.75
windHeight=windArea*2*25.4 #window height in mm
usefulWindow=windArea*0.6
idxLam=vamaxList.index(x)
idxEcoLam=idxLam-1
vamax=vamaxList[idxLam]
slctLam=dictLam[vamax] #Lamination selected
print "You need lamination number " +str(slctLam)+ " for your
work."
I am creating a variable in the for loop. Shouldn't it work outside it?
If not, suggest me some remedy.
Thanks in advance.
