This is the content in a file, I then separate them into lines and parse them. The problem is when I use
or even
re.split(r'\t+', line)
, seeing that the whitespace in between them resemble a tab, I get a problem that it splits them into characters. Help please, I don't understand where I am going wrong.

code for split

datafile = open(filename,'r')
except IOError:
print('Could not open ' + filename)

stypes = {}

for line in datafile.readlines():
if line:
re.split(r'\t+', line)
phone = line[0]
type = line[1]
print(line[0] + ' ' + line[1] + ' ' + line[2])

Answer Source

You are printing the original line not the list with the split results. This should work better:

with open('mywords.txt') as fobj:
    for line in fobj:
        res = line.split()


['AA', 'vowel']
['AE', 'vowel']

The with statement opens a file and will close it as soon as you dedent to the level of with, i.e. fobj will only be open until you write more code on the same level of with (or end your function or program there). This is called a context manager. The context is the indented lines below with.


with open('mywords.txt') as fobj:
    print('closed', fobj.closed)
print('closed', fobj.closed)


closed False
closed True
