Get Access To The First Element Of An Array

def main(): reading = read_file(); display(reading); def read_file(): with open('extra.txt') as fp:#read file lines = fp.read().split(); fp.close(); #close

Solution 1:

To enable access of the 2 and 3 separately, try:

>>> s = '2,3 1,2,3 4,5,6 2,3 10,11 13,14,15 END'  # input from file
>>> s.replace(',', ' ').split()
['2', '3', '1', '2', '3', '4', '5', '6', '2', '3', '10', '11', '13', '14', '15', 'END']

Or, if you want to keep the grouping from your original code and just access the elements one by one:

>>> c = s.split()
>>> c
['2,3', '1,2,3', '4,5,6', '2,3', '10,11', '13,14,15', 'END']
>>> c[0].split(',')
['2', '3']

In your code

def main():
    reading = read_file();
    display(reading);

def read_file():
    with open('extra.txt') as fp:#read file
        s = fp.read()
    # No explicit close for fp because it is closed automatically by `with` statement.
    return s.replace(',', ' ').split()

def display(info):
    print info;

main()

Solution 2:

John's answer is perfect, just in case you need to convert it to an array

z = []
sample = ['2,3', '1,2,3', '4,5,6', '2,3', '10,11', '13,14,15', 'END'];
[[z.append(y) for y in x.split(',')] for x in sample]

and you can get the first 2 values by using z[0:2]

So your code should be something like

def main():
    reading = read_file();
    display(reading);

def read_file():
    with open('extra.txt') as fp:#read file
        lines = fp.read().split();
    fp.close(); #close file
    return lines; #return lines to main function

def display(info):
    z = []
    [[z.append(y) for y in x.split(',')] for x in info]
    print z;       # prints ['2', '3', '1', '2', '3', '4', '5', '6', '2', '3', '10', '11', '13', '14', '15', 'END']
    print z[0:2];  # prints ['2', '3']


main();
