ok, emails show post fine. 10 years ago or something, I was quite involved to 
comp.lang.c and I don't remember having this issue. Of course, only Python 
needs formatting speficities but from what I can remember, indentation was 
working fine then. One more thing, is that there was a lot less ads than now. 
And comp.lang.python seems to show more ads than other groups like comp.lang.c

@Greg, then if you want, you can post these from what you're using. I tried 
sending a few times and it seemed it didn't work when refreshing the google 
group discussion page. However, just looking now at the discussion through 
emails, shows indentation right. I'm using firefox. I'll try using chromium for 
later posts if that makes things easier.

Thanks, I'm going to try

As alternative, I pasted it into github and pasted it back into this page, it's 
ok when pasting but when posting it fails keeping spaces... Until I can find a 
way to do it, this is the github link

Re: learning python building 2nd app, need advices

And something important to this app, is about listing files, how to avoid 
listing small application files parts .ini and binary files so if it's an 
application it would tell the size of of the folder of this application and not 
list the content or make it optionnal?

learning python building 2nd app, need advices

[pascal z via Python-list]

Hi,

This is a python app I was working on, can you help making it a beautiful 
looking app like bleachbit or ccleaner?

The whole code below (what it does: it lists all folders and files from a 
specified path and tells some infos like size in mb or gb... and export it to a 
csv file for further processing maybe with customized dashboard...the listing 
should will also be used to rename multiple files to help ordering and finding 
files because current renaming tools are difficult to use I find...) For now it 
just gives infos about folders and files and rename. Maybe a backup tool would 
be nice, please advise. But the code is opposiite to bullet proof and if could 
be more bullet proof, it would be a way to start and continue

the messy code

Thanks for this tip. I do think it's better to use lists than concatenate into 
string variable. However, writing a list to a csv file is not something easy. 
If strings stored into the list have commas and single quotes (like song 
title's), it messes up the whole csv when it first meets this. Example with arr 
as list:


import csv
import io

(...)

csv_contents = "%s;%s;%s;%.2f;%.2f;%.2f;%.2f;%s" % (vfolder_path, vfile_name, 
vfolder_path_full, 0.00, 0.00, 0.00,0.00, "folder")
arr.append([csv_contents])

b = io.BytesIO()
with open(CSV_FILE,'w', newline ='\n') as f:
#write = csv.writer(f,delimiter=';')
#write = csv.writer(f,quotechar='\'', 
quoting=csv.QUOTE_NONNUMERIC,delimiter=',')
write = csv.writer(f,b)
for row in arr:
write.writerows(row)

(...)

string samples: ;'Forgotten Dreams' Mix.mp3;'Awakening of a Dream' Ambient 
Mix.mp3;Best of Trip-Hop & Downtempo & Hip-Hop Instrumental.mp3;2-Hour _ Space 
Trance.mp3

for the titles above, the easiest thing to write csv for me is 


(...)
csv_contents += "%s;%s;%s;%.2f;%.2f;%.2f;%.2f;%s" % (vfolder_path, vfile_name, 
vfolder_path_full, 0.00, 0.00, 0.00,0.00, "folder"

with open(CSV_FILE,'w') as f:
f.write(csv_contents)


csv_contents can be very large and it seems to work. It can concatenate 30k 
items and it's ok. Also with the above, I have the expected result into each of 
the 8 rows having the corresponding data. This is not always the case with csv 
writerows. If it meets a character it can't process, from there everything go 
into a single cell row. The split on semi colon from doesnt work anymore.

I am not allowed to change the name of the files (it could be used later 
somewhere else, making side effects...).

Very good point, it should what caused the issue

By the way, it seems it's ok to check \n as end of line, it will work on 
windows linux and mac platforms even if windows use \r\n

python if and same instruction line not working

[pascal z via Python-list]

I need to change the script commented out to the one not commented out. Why?

# for x in sorted (fr, key=str.lower):
# tmpstr = x.rpartition(';')[2]
# if x != csv_contents and tmpstr == "folder\n":
# csv_contentsB += x
# elif x != csv_contents and tmpstr == "files\n":
# csv_contentsC += x

for x in sorted (fr, key=str.lower):
if x != csv_contents:
tmpstr = x.rpartition(';')[2]
if tmpstr == "folder\n":
csv_contentsB += x
elif tmpstr == "file\n":
csv_contentsC += x

Re: python show folder files and not subfolder files

[pascal z via Python-list]

ok, i came up with 
if os.path.isfile(path)
following 
path = os.path.join(Lpath, f)

and it seems to be ok, no dupplicates or wrong sizes...

thanks

Please advise if the following is ok (i don't think it is)

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import os

csv_contents = ""
output_file = '/home/user/Documents/csv/output3csv.csv'
Lpath = '/home/user/Documents/'

csv_contents = "FOLDER PATH;Size in Byte;Size in Kb;Size in Mb;Size in Gb\n"

d_size = 0
for root, dirs, files in os.walk(Lpath, topdown=False):
for i in files:
d_size += os.path.getsize(root + os.sep + i)
csv_contents += "%s   ;%.2f   ;%.2f   ;%.2f   ;%.2f  \n" % (root, d_size, 
d_size/1024, d_size/1048576, d_size/1073741824)

counter = Lpath.count(os.path.sep)
if counter < 5:
for f in os.listdir(Lpath):
path = os.path.join(Lpath, f)
f_size = 0
f_size = os.path.getsize(path)
csv_contents += "%s   ;%.2f   ;%.2f   ;%.2f   ;%.2f  \n" % (path,

python show .

[pascal z via Python-list]

Hello, I'm working on a script where I want to loop into folders somehow 
recursively to get information but I want to limit the infos for the files on a 
certain level of folders for example:

/home/user/Documents/folder1
/home/user/Documents/folder2
/home/user/Documents/folder3/folder1/file1
/home/user/Documents/folder4/file1
/home/user/Documents/file1
/home/user/Documents/file2
/home/user/Documents/file3

I only want file1, 2, 3 at the root of Documents to show (write to a csv) and 
I'm using the script below

### SCRIPT###
#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import os

csv_contents = ""
output_file = '/home/user/Documents/csv/output2csv.csv'
Lpath = '/home/user/Documents/'

csv_contents = "FOLDER PATH;Size in Byte;Size in Kb;Size in Mb;Size in Gb\n"

for root, dirs, files in os.walk(Lpath, topdown=False):
counter = Lpath.count(os.path.sep)
if counter < 5:
for f in os.listdir(root):
path = os.path.join(root, f)
f_size = 0
f_size = os.path.getsize(path)
csv_contents += "%s   ;%.2f   ;%.2f   ;%.2f   ;%.2f  \n" % (path, 
f_size, f_size/1024, f_size/1048576, f_size/1073741824)

fp = open(output_file, "w")
fp.write(csv_contents)
fp.close()
### END OF SCRIPT###

When I run this script, I get files in subfolders. For now, I need to keep 
using "os.walk" because the script includes functions that I didn't include to 
make thing simple.

python oop learning communication between function inside a class

[pascal z via Python-list]

Hello,
I would like to know how possible it is to call a member function from a class 
and pass it a variable

Example:

class Application(tk.Frame):
"""docstring for ."""

def __init__(self, parent):
super(Application, self).__init__(parent)
self.parent = parent
parent.title('Courses selections')
#parent.geometry("700x350")
parent.geometry('500x320+0+0') #Width x Height
# Create widgets/grid
self.create_widgets()
self.selected_item = 0

def create_widgets(self):
### FIRST NAME LABEL + ENTRY
self.firstName_txt = tk.StringVar()
self.firstName_lbl = tk.Label(self.parent, text='First Name', 
font=('bold'))
self.firstName_lbl.place(x=20,y=10)
self.firstName_entry = tk.Entry(self.parent, 
textvariable=self.firstName_txt)
self.firstName_entry.place(x=120,y=10)

...


def prereq(self):
self.boo = 1

if self.firstName_txt.get() == "":
msg.showwarning("Missing information", "First name info missing")
boo = 0
elif self.lastName_txt.get() == "":
msg.showwarning("Missing information", "Last name info missing")
boo = 0
elif self.age_txt.get() == "":
msg.showwarning("Missing information", "Age info missing")
boo = 0
elif self.rBtnGender.get() == 0:
msg.showwarning("Missing information", "Gender info missing")
boo = 0

if self.boo == 1:
self.fname = self.firstName_txt.get()
self.lname = self.lastName_txt.get()
self.age = int(self.age_txt.get())

self.selectedCourse = 
self.coursesLBX.get(self.coursesLBX.curselection())

if self.age < 21:
msg.showwarning("Invalid Age", "Invalid Age, you are not 
eligible")
return
elif self.age >= 21:
pass

### SELECTED COURSE
if self.selectedCourse == "Quality Management (Adv.)":
self.prereq = "The prereq for this course is Quality Management 
(Int)."
self.flag = 1
elif self.selectedCourse == "Financial Management (Adv.)":
self.prereq = "The prereq for this course is Financial 
Management (Bas)."
self.flag= 1
elif self.selectedCourse == "Project Management (Adv.)":
self.prereq = "The prereq for this course is Project Management 
(Int)."
self.flag = 0
else:
self.prereq = "The prereq for this course is Project Management 
(Bas)."
self.flag = 0

### PART TIME
if self.chkBtnPTime.get() == 1 and self.flag == 0:
self.str2 = "\nThis course is not available part time."
elif self.chkBtnPTime.get() == 1 and self.flag == 1:
self.str2 = "\nThis course is available part time."
else:
self.str2 = ""

self.result = self.prereq + self.str2
msg.showinfo('Form info', self.result)


def save2db(self):
try:
db.insert(self.fname, self.lname, self.age)
msg.showinfo('DB action', "Selection inserted into db")
except:
msg.showinfo("Form submission failed", "Plz check ur input")

##

all script available on github 
https://github.com/barpasc/python_tuto_400_oop

In function save2db, I would like to know if there is any alternative to using 
try/except. The alternative I'm thinking is something like 

def save2db(self,boo):
   if boo == 1:
  do something
   else:
  do something like return to previous step...

Is this possible?
