I'm a beginner so dont beat me up too much :) .I have a program where a user enters a product number into a field and clicks a search button, the program then opens a csv file (see below), looks for that product number and should then only display (by inserting that data into a treeview) the data relevant, stopping once blank rows occur - this indicates the end of the part information and the start next part.
Example of the csv is below (excuse the use of the error box)
Error: Product PartDesc Drawings Issues Documents
1-1841111-2 bad feeling Dwg1 Iss A c:\company\docs\tfpp\widget1.xls
Dwg2 Iss B c:\company\docs\tfpp\bob.pdf
Dwg25 Iss Z c:\company\docs\tfpp\itsatrap.pdf
1-1841111-4 tribble Dwg3 Iss C c:\company\docs\tfpp\wibble.xls
1-1841111-5 nothing Dwg4 Iss D c:\company\docs\tfpp\rocket.pdf
Dwg5 Iss E c:\company\docs\tfpp\dwg1.doc
Unfortunately when I run the code I can only get a single csv row to display and have not been able to work out how get subsequent rows, stopping at a blank row. I am however, not convinced that the below code although its displays a single line as expected is operating correctly.
def search(self):
if self.SOentry.get() != "":
x = self.dwgtree.get_children()
for item in x:
self.dwgtree.delete(item)
self.partdesc.delete(0,'end')
with open("c:\python\projects\somedwgs.csv") as csvfile:
reader = csv.DictReader(csvfile)
for row in reader:
result=(row['Product'])
if self.SOentry.get() == result:
descr=(row['PartDesc'])
descDwg=(row['Drawings'])
descIss=(row['Issues'])
descDscr=(row['Documents'])
self.partdesc.insert(0,descr)
while True:
#if row['PartDesc'] != "":
if descDwg != "":
self.dwgtree.insert("",'end',values=(descDwg,descIss,descDscr))
next(reader)
break

quick look, general
You have searchbutton defined twice
I did a search for 1-1841111-2
At line 91, the tree (x) is not populated
self.SOentry.get() = {str} '1-1841111-2'
# ... first read of data file:
OrderedDict([('Product\t PartDesc\t Drawings\t Issues\t Documents', '1-1841111-2\t bad feeling\t Dwg1\t Iss A\t c:\\company\\docs\\tfpp\\widget1.xls')])It then crashes on result = (row['Product'])
because Product is part of a string.
I would do this differently. Give me some time, I'm about to eat dinner

Ok,
I had my dinner.
here's how I would read this file.
The code would have been more compact if the structure were the same from line to line.
Since you are using tkinter, you obviously won't be using the show_current_product function,
but I put it there to show how to access the dictionary.
In addition, I wrote this so that the dictionary could handle multiple products with minor modifications.
Here's the code:
from pathlib import Path
class TryRead:
def __init__(self):
self.header = None
self.product_dict = {}
self.file = Path('.') / 'somedwgs.csv'
def search(self, product_id):
with self.file.open() as f:
# skip first line (header)
next(f)
self.product_dict = {}
product_found = False
for line in f:
line = line.strip().split('\t')
if not product_found:
if line[0] != product_id:
continue
product_found = True
llen = len(line)
if llen == 1:
break
elif llen == 5:
product = line[0]
part_desc = line[1]
self.product_dict[product] = {}
self.product_dict[product]['PartDesc'] = part_desc
self.product_dict[product]['Drawings'] = {}
self.product_dict[product]['Drawings'][line[2]] = {}
self.product_dict[product]['Drawings'][line[2]]['Issues'] = line[3]
self.product_dict[product]['Drawings'][line[2]]['Documents'] = line[4]
else:
self.product_dict[product]['Drawings'][line[0]] = {}
self.product_dict[product]['Drawings'][line[0]]['Issues'] = line[1]
self.product_dict[product]['Drawings'][line[0]]['Documents'] = line[2]
# print(f'product_dict: {self.product_dict}')
def show_current_product(self):
if not self.product_dict:
print('Please select a product')
else:
for key, value in self.product_dict.items():
print(f'Product: {key}')
for skey, svalue in value['Drawings'].items():
print(f' {skey}')
for ikey, ivalue in svalue.items():
print(f' {ikey}: {ivalue}')
if __name__ == '__main__':
tr = TryRead()
tr.search('1-1841111-2')
tr.show_current_product()and the results:
Output: Product: 1-1841111-2

thank you for your help, its close to what I'm looking for except that I will be inserting the data into a tree widget that has three columns. So in my case if I searched for 1-1841111-2 I would be aiming to see :
DRAWING.........ISSUE.............DOCUMENT TYPE
Dwg 1.................Iss A.................c:\company\docs\tfpp\widget1.xls
Dwg 2.................Iss B.................c:\company\docs\tfpp\bob.pdf
Dwg 25...............Iss Z.................c:\company\docs\tfpp\itsatrap.pdf
with other part searches bring up other data in the above layout

But it's a simple process to manipulate the dictionary into any format that you need.
from pathlib import Path
class TryRead:
def __init__(self):
self.header = None
self.product_dict = {}
self.file = Path('.') / 'somedwgs.csv'
self.out_field_size = 22
def search(self, product_id):
with self.file.open() as f:
# skip first line (header)
next(f)
self.product_dict = {}
product_found = False
for line in f:
line = line.strip().split('\t')
if not product_found:
if line[0] != product_id:
continue
product_found = True
llen = len(line)
if llen == 1:
break
elif llen == 5:
product = line[0]
part_desc = line[1]
self.product_dict[product] = {}
self.product_dict[product]['PartDesc'] = part_desc
self.product_dict[product]['Drawings'] = {}
self.product_dict[product]['Drawings'][line[2]] = {}
self.product_dict[product]['Drawings'][line[2]]['Issues'] = line[3]
self.product_dict[product]['Drawings'][line[2]]['Documents'] = line[4]
else:
self.product_dict[product]['Drawings'][line[0]] = {}
self.product_dict[product]['Drawings'][line[0]]['Issues'] = line[1]
self.product_dict[product]['Drawings'][line[0]]['Documents'] = line[2]
# print(f'product_dict: {self.product_dict}')
def generate_output(self):
if not self.product_dict:
print('Please select a product')
else:
for key, value in self.product_dict.items():
for skey, svalue in value['Drawings'].items():
dlen = self.out_field_size - len(skey)
dlen2 = self.out_field_size - len(svalue['Issues'])
outstr = f"{skey}{'.' * dlen}{svalue['Issues']}{'.' * dlen2}{svalue['Documents']}"
yield outstr
def show_formatted_product(self):
for line in self.generate_output():
print(line)
def show_current_product(self):
if not self.product_dict:
print('Please select a product')
else:
for key, value in self.product_dict.items():
print(f'Product: {key}')
for skey, svalue in value['Drawings'].items():
print(f' {skey}')
for ikey, ivalue in svalue.items():
print(f' {ikey}: {ivalue}')
if __name__ == '__main__':
tr = TryRead()
tr.search('1-1841111-2')
tr.show_current_product()
print('')
tr.show_formatted_product()output (sans the header):
Output: Product: 1-1841111-2
