Question

I have got this function in my program.

def time(transcriptionFile) :
    ''' This function changes the time values in secs from the transcription file and keeps a list of start time and duration for each phoneme.'''
    with open("transcriptions.txt", "r") as tFile :
        timeList = []
        parameterList = []
        frame = 0.04
        lines = 0
        for line in tFile :
            lines += 1
            for i in range(lines) : 
                i = i * frame
            timeList.append(i)
            li = line.split()
            if li :
                start_time = (int(li[0]) / 10000000.)
                end_time = (int(li[1]) / 10000000.) 
                duration = ((int(li[1]) -int(li[0]))/10000000.)

                poly = poly_coeff(start_time, end_time, i)
                Newton(poly, parameterList) 

I want to use i as an argument in poly_coeff. The number of times this function is called is the number of lines in the file. And i is increasing with each line. So when the function is called for the first time the first i value should should be passed as argument then second time the second i value should be passed and so on.

I have certainly done it wrong here I can see but can’t figure out how to do it in a right way. Also I guess too much is going on inside a single function. Is it better to split it? But everything is to do with opening the same file.

Answer 1

If you want the line number then you should do

poly = poly_coeff(start_time, end_time, lines)

If you want to use line number * frame
then do

poly = poly_coeff(start_time, end_time, lines * frame)

I dont know what you are trying to do with

for i in range(lines) : 
    i = i * frame
