Accidentally the number of function definitions does not help the clarity of
the program, even though it's completely unclear to me what exactly you are
trying to do. :-)
I rewrote your program a bit combining the definition of the functions, the
comparision of the functions and removed the chance that your program goes
on the define/compare values that have not been defined.
*** Insert redone code ***
altura_aeronave = 0
largura_aeronave = 0
comprimento_aeronave = 0
comprimento = 0
largura = 0
altura = 0
global altura, altura_aeronave, comprimento, comprimento_aeronave, \
if not largura <= largura_aeronave:
print 'Volume largo demais!'
elif not altura <= altura_aeronave:
print 'Volume alto demais!'
elif not comprimento<=comprimento_aeronave:
print 'Volume comprido demais!'
global largura, altura, comprimento
global altura_aeronave, largura_aeronave, comprimento
porao = input()
if porao == 1 :
altura_aeronave = 111
largura_aeronave = 112
comprimento = 211
elif porao == 4:
altura_aeronave = 112
largura_aeronave = 113
comprimento = 212
print "Porao inexistente!"
