And I want to read it into pandas data frame for further analysis. As you can see the header is different for each subset and also the format of the data. I thought to use re module and pandas for reading the data into frame but don't know how to do it in most efficent way. Also as you can see the AIR string is common to both headers. In the full file there would be more such strings so I would like to create for each string like that a class which attributes (node, conductor) will be a pd dataframe with corresponding data.
Any help will be appreciated:)
edit: Following Alexandre suggestion I've altered a code a little bit but still didn't find a way to put the data into class
# import modules
import pandas as pd
from io import StringIO
class TableData:
def __init__(self,name):
self.name = name
self.nodes_table = self.add_nodes()
self.conductor_table = self.add_conductors()
def add_nodes(self):
pass
def add_conductors(self):
pass
out = []
submodels = set()
with open("case1.cc", "r") as f:
sub = ""
for line in f.readlines():
if ("VARIABLES" in line) or ("OPTIONS" in line): # skip non relevant
# blocks
continue
if line.startswith('C'): # skip comments line
continue
if ("HEADER" in line) and ("DATA" in line):
# Get submodel name and add to set if not present
submodels.add(line.split(',')[1])
# Get type of data
type = line.split()[1]
# Skip first insertion
if sub != "":
out.append(sub)
sub = ""
else: sub += line
# Append last sub (outside for loop)
out.append(sub)
# "out" is a list of pandas dataframes
out = [pd.read_csv(StringIO(o), sep=r",*\s{2,}", header=None, engine="python") for o in out]

You can try the following approach:
- Read the file line by line using
f.readlines() - For each line, check if the line contains
HEADER.- If it's the case, that means this a new sub df. Add it to the output
- Else: append the current line to the current sub data
- Convert the list of
subdf in text format to pandas dataframe. This discussion explains how. Note:- The regex used is
,*\s{2,}that means:- match any "
," with ",*" - match any all 2 and more space using
"\s{2,}
- match any "
- The argument
header=Noneis required either the first line will be used add columns name.
- The regex used is
Full code
# import modules
import pandas as pd
from io import StringIO
out = []
with open("data.txt", "r") as f:
sub = ""
for line in f.readlines():
if "HEADER" in line:
# Skip first insertion
if sub != "":
out.append(sub)
sub = ""
else: sub += line
# Append last sub (outside for loop)
out.append(sub)
# "out" is a list of pandas dataframes
out = [pd.read_csv(StringIO(o), sep=r",*\s{2,}", header=None, engine="python") for o in out]
print(out[0])
# 0 1 2
