Hi all,
Please consider two strings
line_a
'12345678abcdefgh12345678'
line_b
'12345678 abcdefgh 12345678'
line_b.split()
['12345678', 'abcdefgh', '12345678']
Is it possible to split line_a such that the output is
['12345678', 'abcdefgh', '12345678']
Mmh, your question is a bit too generic.
Indeed. I would like to split strings made of digits after eight characters each.
line_a
'111111.1222222.2333333.3'
line_b
'111111.1 222222.2 333333.3'
line_b.split()
['111111.1', '222222.2', '333333.3']
How can I accomplish that ?
would this suit you ?
np.asarray(line_b,dtype=[('hdr','|S8'),('mid','|S8'),('tail','|S8')])
array(('111111.1', '222222.2', '333333.3'), dtype=[('hdr', '|S8'), ('mid', '|S8'), ('tail', '|S8')])
hth, sebastien.

here is my workaround.
from numpy import arange line_a = '111111.1222222.2333333.3' # without separator line_b = '111111.1 222222.2 333333.3' # including space as a delimiter
div, mod = divmod(len(line_a),8) liste = [] for j in arange(0,div): liste.append(line_a[j*8:(j+1)*8])
print liste
print line_b.split() # Works for line_b but not for line_a
Cheers, Nils
hi,

from numpy import arange line_a = '111111.1222222.2333333.3' # without separator line_b = '111111.1 222222.2 333333.3' # including space as a delimiter
div, mod = divmod(len(line_a),8) liste = [] for j in arange(0,div): liste.append(line_a[j*8:(j+1)*8])
print liste
print line_b.split() # Works for line_b but not for line_a
how about this, then:
import numpy as np def massage(data): fmt = np.dtype([('hdr', '|S8'), ('mid', '|S8'), ('tail','|S8')]) data = data.replace(' ','') assert len(data)==3*8, "contract failed or invalid assumption" return np.asarray(data,dtype=fmt).tolist()
assert(massage(line_a) == massage(line_b))
cheers, sebastien.
