search in dict inside tuple

[steg]

In the following functions, i want to search, for example, the string 'BAB' in hmm. The code cannot find it and i could not fix it. Thanks for your help

def TrialSystem () :
hmm = {}
hmm [0] = ({ 'A ' :0.3 , 'B ' :0.2 , 'C ' :0.5 } , 1 )
hmm [1] = ({ 'A ' :0.1 , 'B ' :0.8 , 'C ' :0.1} , 2)
hmm [2] = ({ 'A ' :0.4 , 'B ' :0.6} , -1 )
return hmm

def ERecall ( hmm , strng ) :
prb = 1
N = len ( strng )
for i in range ( N ) :
if strng [ i ] in hmm [ i ][0]:
prb *= hmm [ i ][0][ strng [ i ] ]
else :
prb = 0
break
return prb

Please, fix the identation and use proper tags when post code, traceback, output, etc.
See BBcode help for more info.

You have spaces in the key values, so when you are searching for B, the key that you're looking for is in fact B .

I think that your TrialSystem(): needs to be:

def TrialSystem():
    hmm = {}
    hmm[0] = ({'A': 0.3, 'B': 0.2, 'C': 0.5}, 1)
    hmm[1] = ({'A': 0.1, 'B': 0.8, 'C': 0.1}, 2)
    hmm[2] = ({'A': 0.4, 'B': 0.6}, -1)
    return hmm

How hope this is of help.
