Hi i have a python script which is reading the values defined in ConfigParser sections.I am able to get the values from the sections and putting into a diffrent variable to use it further.
For example,
[path]
DB_CONFIGURATION_PATH:/opt/aor/regression/test_scenario/Config.cfg
[section1]
localhost:127.0.0.1
username:root
password:root
DB_name:test
Script1:
#!/usr/bin/python
import ConfigParser
configParser = ConfigParser.RawConfigParser()
configParser.read('/opt/aor/regression/test_scenarios/Config.cfg')
dbconfig_path = configParser.get("Regression_script_path","DB_CONFIGURATION_PATH")
Script2:
#!/usr/bin/pythoni
import os
import sys
#import ReadConfigurationFile
from ReadConfigurationFile import *
db_path=dbconfig_path
config = ConfigParser.ConfigParser()
config.read('db_path')
host=config.get("section1","localhost")
print host
This is throwing error as :
ConfigParser.NoSectionError: No section: 'section1'
Can you tell me what is the problem here?

I have a script that have multiple files and a config file with all the variables store in one Python file.
Folder structure:
Config file:
If I try to run the main file which calls the head function imported, an error pops up saying that the config cannot be imported.
Imports:
Your Functions folder has a __init__.py file. If your app executes from Main.py (ie if Main.py satisfies __name__ == "__main__") therefore wherever you are in your app you could import the config like this:
from Functions.Config import *
Edit:
However,from module import * is not recommended with local import. You could give an alias to the import and call name.variable instead of calling name directly.
Example:
def head():
# import packages
import Function.Config as conf
print(conf.more_200)
head()
>>> 50
Your syntax are wrong.
It is supposed to be from Config import * and not import .Config import *
I am pretty new to python and have been working on a data validation program. I am trying to run my main.py file but I am getting the following error.
Traceback (most recent call last):
File "/Users/user/data_validation/main.py", line 5, in <module>
from src.compile_csv import combine_csv_files
File "/Users/user/data_validation/src/compile_csv.py", line 5, in <module>
from helpers.helper_methods import set_home_path
ModuleNotFoundError: No module named 'helpers'
I am using python version 3.94
This is my folder structure
data_validation
- src
- files
validation.csv
- folder_one
combined.csv
- folder_two
combined_two.csv
- helpers
helper_methods.py
compile_csv.py
mysql.py
split.py
main.py
Both compile_csv.py and split.py use methods from helpers.helper_methods.py
My main.py which is throwing the error when being run, looks like the following:
import os
import sys
import earthpy as et
from src.mysql import insert_data, output_non_matches
from src.compile_csv import combine_csv_files
from src.split import final_merged_file
from src.helpers.helper_methods import set_home_path, does_file_exist
home_path = et.io.HOME
file_path = home_path, "data_validation", "src", "files"
folder_name = sys.argv[1]
def configure_file_path():
master_aims_file = os.path.join(
file_path, "validation.csv")
output_csv = os.path.join(
file_path, "output.csv.csv")
gdpr_file_csv = set_home_path(folder_name + "_output.csv")
output_csv = does_file_exist(os.path.join(
file_path, folder_name + "_mismatch_output.csv"))
return output_csv, master_aims_file, gdpr_file_csv
output_csv, master_aims_file, gdpr_file_csv = configure_file_path()
if __name__ == "__main__":
print("🏁 Finding names which do not match name in master file")
if (folder_name == "pd") and (folder_name == "wu"):
final_merged_file()
else:
combine_csv_files()
insert_failures = insert_data(output_csv, master_aims_file)
output_failures = output_non_matches(output_csv, gdpr_file_csv)
if insert_failures or output_failures:
exit(
"⚠️ There were errors in finding non-matching data, read above for more info"
)
os.remove(os.path.join(home_path, "data_validation", "members_data.db"))
exit(
f"✅ mismatches found and have been outputted to {output_csv} in the {folder_name} folder")
From what I understand in python 3 we do not need to use __init__.py and you can use . for defining the path during import, So I am not entirely sure as to what I am doing wrong.
I am executing the file from /Users/user/data_validation and using the following command python main.py pd
There it is. The error is happening in your compile_csv.py file. I'm guessing in that file you have from helpers.helper_methods import blah. But you need to change it to
from .helpers.helper_methods import blah
OR
from src.helpers.helper_methods import blah
Reason being is that imports are relative to cwd not to the file where the code is running. So you need to add the import relative to /Users/user/data_validation.
you can try by setting PYTHONPATH variable. check more about it here
Importing UTILS classes into Inventory - can it be done?
I have created a custom LDAP data importer as part of creating my inventory class. The LDAP schema we have wasn't similar enough to the LDAP plugin provided in samples.
My class is called ldapDataModule; the class is in:
/home/agt/ansible/agt_module_utils/ldapDataModule.py
My "$HOME/.ansible.cfg" file has the following:
module_utils = /home/agt/ansible/agt_module_utils
When running my Ansible inventory module, I get the following output:
ansible ecomtest37 -m ping
ERROR! Attempted to execute "/sites/utils/local/ansible/hosts" as
inventory script: Inventory script (/sites/utils/local/ansible/hosts) had
an execution error: Traceback (most recent call last):
File "/sites/utils/local/ansible/hosts", line 22, in
from ansible.module_utils import ldapDataModule
ImportError: No module named module.utils
The include statement inside hosts appears like this:
import copy
import ldap
import re
import sys
import operator
import os
import argparse
import datetime
import os.path
try:
import json
except:
import simplejson as json
from ansible.module_utils import ldapDataModule
class agtInventory(object):
RECOMENDATIONS?
I was able to do the following as a "work around". I'd still like to hear from Ansible guru's on proper use of "module_utils" variable from ansible.cfg
sys.path.insert(0, '/home/agt/ansible/agt_module_utils')
from ldapDataModule import ldapDataModule
I've been working on a python script that will require multiple libraries to be imported.
At the moment my directory structure is
program/
main.py
libs/
__init__.py
dbconnect.py
library01.py
library02.py
library03.py
My dbconnect.py which has the following contents
import psycopg2
class dbconnect:
def __init__(self):
self.var_parameters = "host='localhost' dbname='devdb' user='temp' password='temp'"
def pgsql(self):
try:
var_pgsqlConn = psycopg2.connect(self.var_parameters)
except:
print("connection failed")
return var_pgsqlConn
I am able to import and use this in my main.py using
from libs.dbconnect import dbconnect
class_dbconnect = dbconnect()
var_pgsqlConn = class_dbconnect.pgsql()
This works as expected however I am trying to import all of the library scripts each which have similar contents to bellow
def library01():
print("empty for now but this is library 01")
I have added to my __init__.py script
__all__ = ["library01", "library02"]
Then in my main.py I tried to import and use them as bellow
from libs import *
library01()
I am getting the following error
TypeError: 'module' object is not callable
I'll suppose content in your library0x.py are different (the functions/class have different names)
The best way is to import all your subfiles content in the __init__.py
# __init__.py
from .dbconnect import *
from .library01 import *
from .library02 import *
from .library03 import *
Then you can use the following :
from libs import library01, library02
If you want to restrict for some reasons importation with the wildcard (*) in your library0x.py files, you can define a __all__ variable containing all the names of the function you will import with the wildcard :
# library01.py
__all__ = ["library01"]
def a_local_function():
print "Local !"
def library01():
print "My library function"
Then, by doing from .library01 import *, only the function library01 will be import.
EDIT: Maybe i missunderstand the question : here are some ways to import the function library01 in the file library01.py :
# Example 1:
from libs.library01 import library01
library01()
# Example 2:
import libs.library01
libs.library01.library01()
# Example 3:
import libs.library01 as library01
library01.library01()
In your case library01 is a module which contains a function named library01. You import the library01 module and try to call it as a function. That's the problem. You should call the function like this:
library01.library01()
Chaps I am going through what is apparently a #1 problem for python novice. I have been through some tutorials but I really can t get it works. Here is the code :
import time
from settings import *
from actif_class import *
from get_settings import *
from dataython import *
from spreadython import *
from tankython import *
if __name__ == "__main__":
t0 = time.clock()
settings = get_settings()
tickers = get_data_mp(settings)
list_spreads = get_list_spread(tickers,settings)
list_spreads_tank = tanking(list_spreads,settings)
spread_traitable = obtention_spreads_traitables(list_spreads_tank,settings)
print 'done. Timing',time.clock()-t0,'seconds'
and here is the stack :
ImportError: No module named datayhton
Even though the module DOES exist and is in the same folder as every other modules. It is able to see the get_settings one but not dataython. I ve tried on another machine but still got the same trouble.
I tried to go through import sys, sys.path.append but I might have done something wrong because it still doesnt work.
Any help would be much appreciated.
EDIT : still doesnt work when I write this on top of my code :
import time
import sys
sys.path.append("/path/to/dataython")
Ok. I got it now. Not a no brainer so here is the amended code :
import time
import sys
sys.path.append("path/to/your/file")
import your_file
the mistake I was doing was keep writing :
from your_file import *
