[Tutor] Read a matrix with lines in different behavior

[Felipe Melo]

Hello, 

I want to read the below matrix, identify when the characters in front of "want = " are equal to "1" and then save in an array and in an output file the characters above. But I don't know how to identify the second line and store in a variable:

alpha=0 beta=2 gamma=50
want = 0 
alpha=0 beta=2 gamma=50
want = 1 
alpha=0 beta=2 gamma=50
want = 0 
alpha=0 beta=2 gamma=50
want = 1 
alpha=0 beta=2 gamma=50
want = 0 


This is part of the code:

    try:
        datadir = '/home/me/Test_python/'
        
    fileHandle = open( "%s/teste.txt"%datadir, 'r'
 )
        vector = [ ]
        for line in fileHandle.readlines():
            line=line.strip()
            a = line.split(" ")[0]
            print a    
            b = line.split(" ")[1]
            print b
            c = line.split(" ")[2]
            print c
            d = line.split(" ")[3]
            print d
            if d == "1":
               vector.append([a,b,c])
               n = n + 1
        fileHandle.close()
    file = open("saida.txt","w")
        for cont in range(n):
            file.write = vector


    except:
        print "Exception"
        sys.exit( 1 )


When I execute the code there is an error when the loop finds the second line


[felipe at grumari Test_python]$ python verificar.py 
alpha=0
beta=2
gamma=50
Exception



Thanks,
Felipe
