list index out of range

[mcgrim]

I am converting a list of times and dates taken from a file into european time.
The conversion function seems to do its job, but when I go and print the outcome,
i can only print the first value.
The list of original times is over 200000 values but with this new conversion,
only the first value is the one that shows.
In order for what I am saying to make sense, kindly refer to my code and its comments.
If the info I am giving are not clear/enough, please say something.
How do I fix this and make sure that this function has as many values as the original list of dates?

def last_digits(num, last_digits_count=2):
    return abs(num) % (10**last_digits_count)

orig_date=[]
orig_time=[]
movements=[]

with open('bird_jan25jan16.txt', 'r') as f:
    for line in f:
        data = line.split()    # Splits on whitespace        
        orig_date.append(data[0][:])
        orig_time.append((data[1][:]))
        movements.append(int(data[2][:]))
    for i in range(0,len(orig_date)):
        if ((len(str(movements[i-1])) - len(str(movements[1]))) >=2):            
            if movements[i]==0 or (  (movements[i-1] == movements[i+1] ) and  (last_digits(movements[i-1]) == last_digits(movements[i]))):
                movements[i]=((movements[i-1]+movements[i+1])/2)

I hope to get some help.
Again, if additional info are needed, don't hesitate to ask.

Try this. Fix is in "convert_local_timezone"

        orig_date.append(data[0][:])
        orig_time.append((data[1][:]))
        movements.append(int(data[2][:]))
    for i in range(0,len(orig_date)):
