python: input is not matching
Question: 
    import os
    import fileinput
    
    filenames1=os.listdir("./chi_square_metal_region_1")
    filenames1.sort()
    
    for line in fileinput.input("./test_input.dat"):
        for eachfile in filenames1:
            if eachfile == line:
                print yes 
    

I don't get any errors when I run this code, but it's not printing 'yes',
which is the expected output.

It should print 'yes' twice as I there are two files in input which match with
`eachfile`. Why is it not printing the expected output?


Answer: The problem is that:

    
    
    for line in fileinput.input("./test_input.dat"):
    

the variable line will contain '\n' at the end. Try this:

    
    
    import os
    import fileinput
    
    filenames1=os.listdir("./chi_square_metal_region_1")
    filenames1.sort()
    
    for line in fileinput.input("./test_input.dat"):
        for eachfile in filenames1:
            if eachfile == line[:-1]:
                print yes
