Stripping whitespace

[ryan k]

Hello. I have a string like 'LNAME
PASTA ZONE'. I want to create a list of those words and
basically replace all the whitespace between them with one space so i
could just do lala.split(). Thank you!

You *can* just do ``lala.split()` `:

In [97]: lala = 'LNAME PASTA ZONE'

In [98]: lala.split()
Out[98]: ['LNAME', 'PASTA', 'ZONE']

So when you go to the Python interactive prompt and type firstly
lala = 'LNAME PASTA ZONE'
and then
lala.split()
what do you see, and what more do you need to meet your requirements?

Using the split method is the easiest!

That is (a) excessive for the OP's problem as stated and (b) unlike
str.split will cause him to cut you out of his will if his problem
turns out to include leading/trailing whitespace:

>>lala = ' LNAME PASTA ZONE '
>>import re
>>re.split(r'\s +', lala)

['', 'LNAME', 'PASTA', 'ZONE', '']

>>lala.split( )

['LNAME', 'PASTA', 'ZONE']

Read my lips: *you* counting dashes is dumb. Writing your code so that
*code* is counting dashes each time it opens the file is smart.

The above comment is a nonsense.

if counter == 0:
# This line contains the columns, parse it
column_list = line.split()

In generality, you would have to allow for the headings to contain
spaces as well -- this means *saving* a reference to the heading line
and splitting it *after* you've processed the line with the dashes.

elif counter == 1:
# These are the dashes
line_l = line.split()
column_width = [len(i) for i in line_l]

Whoops.
column_width = [len(i) + 1 for i in line_l]

print column_width
else:
# This is a row, parse it
marker = 0
row_vals = []
for col in column_width:
start = sum(column_widt h[:marker])
finish = sum(column_widt h[:marker+1])
print line[start:finish].strip()

If you had printed just line[start:finish], it would have been obvious
what the problem was. See below for an even better suggestion.

row_vals.append (line[start:finish].strip())
marker += 1

Using sum is a tad ugly. Here's an alternative:

row_vals = []
start = 0
for width in column_width:
finish = start + width
#DEBUG# print repr(line[start:finish].replace(' ', '~'))
row_vals.append (line[start:finish].strip())
start = finish

self.rows.appen d(Row(column_li st, row_vals))
counter += 1

Something obvious you can see wrong with my start finish code?

See above.

Please tell me you're making fun of the poor newbie and didn't mean to
seriously suggest using a regex merely to split on whitespace?

Much thanks to Machin for helping with the parsing job. Steven
D'Aprano, you are a prick.

Because his tone is extremely condescending and quite frankly
annoying. From this post to others, his terse remarks scar this
community and fade its atmosphere of friendliness.
