Tkinter: AttributeError: NoneType object has no attribute <attribute name>
(4 answers)
Closed 3 years ago.
The code I have attached below functions like this: It takes users ID and marks. It goes through an excel sheet and finds that specific ID. Then it will update the second column in that row with his marks.
However, this code gives me an error when I run it. The error comes from .get() function used for getting value of an Entry. I have used .get() function in other projects where it works.
import xlwt
import xlrd
from xlutils.copy import copy
from tkinter import *
root = Tk()
root.title("Quiz marks uploader")
root.geometry("500x500")
rnn = "global"
maar = "global"
def upload():
rn = entry_1.get()
mar = entry_2.get()
rnn = rn
maar = mar
button_1 = Button(root, text = "Upload", command = upload).place(relx = 0.3,rely = 0.2,anchor = NE)
label_1 = Label(root, text = "Enter Reg No here").place(relx = 0.2,rely = 0.05,anchor = E)
entry_1 = Entry(root).place(relx = 0.5,rely = 0.05,anchor = E)
label_2 = Label(root, text = "Enter marks here").place(relx = 0.2,rely = 0.1,anchor = E)
entry_2 = Entry(root).place(relx = 0.5,rely = 0.1,anchor = E)
workbook = xlrd.open_workbook("file.xls")
sheet = workbook.sheet_by_index(0)
rb = xlrd.open_workbook("file.xls")
wb = copy(rb)
w_sheet = wb.get_sheet(0)
for row in range(sheet.nrows):
row_value = sheet.row_values(row)
if row_value[0] == rnn:
w_sheet.write(row,1,maar)
print (row_value)
wb.save("file.xls")
root.mainloop()
This is where you are going wrong:
You are doing:
entry_1 = Entry(root).place(relx = 0.5,rely = 0.05,anchor = E)
In this case, the entry_1 is a NoneType object.
And NoneType object doesn't have any property get(), therefore it throws an error.
What you should do:
First instantiate an Entry widget and then give your widget a position in the window using the widget reference.
entry_1 = Entry(root)
entry_1.place(relx = 0.5,rely = 0.05,anchor = E)
Updated code:
import xlwt
import xlrd
from xlutils.copy import copy
from tkinter import *
root = Tk()
root.title("Quiz marks uploader")
root.geometry("500x500")
rnn = "global"
maar = "global"
def upload():
rn = entry_1.get()
mar = entry_2.get()
rnn = rn
maar = mar
button_1 = Button(root, text = "Upload", command = upload).place(relx = 0.3,rely = 0.2,anchor = NE)
label_1 = Label(root, text = "Enter Reg No here").place(relx = 0.2,rely = 0.05,anchor = E)
# entry widget 1
entry_1 = Entry(root)
entry_1.place(relx = 0.5,rely = 0.05,anchor = E)
label_2 = Label(root, text = "Enter marks here").place(relx = 0.2,rely = 0.1,anchor = E)
# entry widget 2
entry_2 = Entry(root)
entry_2.place(relx = 0.5,rely = 0.1,anchor = E)
workbook = xlrd.open_workbook("file.xls")
sheet = workbook.sheet_by_index(0)
rb = xlrd.open_workbook("file.xls")
wb = copy(rb)
w_sheet = wb.get_sheet(0)
for row in range(sheet.nrows):
row_value = sheet.row_values(row)
if row_value[0] == rnn:
w_sheet.write(row,1,maar)
print (row_value)
wb.save("file.xls")
root.mainloop()
Hope it helps!
Instead of xlrd use pandas for managing excel files.
To create simple excel file:
import pandas as pd
df = (pd.DataFrame({'ID': [10, 11, 12], 'Mark': ['ww','zz','cc']}))
df.to_excel('data.xlsx')
I add some changes in elements positions.
Now you can update data like below:
import pandas as pd
from tkinter import *
root = Tk()
root.title("Quiz marks uploader")
root.geometry("500x500")
def upload():
id = entry_id.get()
mark = entry_mark.get()
# load excel into data frame
df = pd.read_excel('data.xlsx', index_col=0)
# find proper row and replace value
row_match = df[df['ID'] == int(id)]
if row_match.shape[0] > 0:
df.at[row_match.index[0], 'Mark'] = mark
# save updated file
df.to_excel('data.xlsx')
# set button and labels
button = Button(root, text = "Upload", command=upload)
button.grid(column=1, row=4)
label = Label(root, text = "Id")
label.grid(column=0, row=2)
entry_id = Entry(root)
entry_id.grid(column=1, row=2)
label = Label(root, text = "Mark")
label.grid(column=0, row=3)
entry_mark = Entry(root)
entry_mark.grid(column=1, row=3)
root.mainloop()

I have a json file which contains some Firewall-rules, then convert it into two different csvs. As the firewall-rules have two different sets with ARules.csv and YRules.csv Don't want to merge it because of the requirement.
Then using splunk we pull the stats which will generate firewall-rules for that day. We then export it with the name - logReport.csv. Let's say there are 50 rows of data
check the results of logReport (data) is present in both the csvs[ARules(150 rows) and YRules(100 rows)]
ARules.loc[ARules['name'].isin(logReport['data'])] - [result - 30]
YRules.loc[YRules['name'].isin(logReport['data'])] - [result - 20]
What I am trying to achieve here is to create a process, where I call the api, and convert that JSON into multiple csv and display it in "tkinter" in two different frames one for ARules and other for YRules, then ask the user to import that logReport.csv using "filedialog or opencsv" and then get the matching/difference results and export it to csv.
my code
import pandas as pd
import json
f = open("/Users/Documents/Info/data.json")
data = json.load(f)
f.close()
ARules = pd.DataFrame(data['ARules'])
YRules = pd.DataFrame(data['YRules'])
csvfile = "/Users/Downloads/logReport.csv"
logReport = pd.read_csv(csvfile,error_bad_lines=False, engine="python")
ARulesV1 = ARules.loc[ARules['ARules'].isin(logReport['data'])]
YRulesV1 = XRules.loc[XRules['YRules'].isin(logReport['data'])]
I was able to do this much but not able to display the output on GUI.

I want to know how do u delete text inside the Tkinter. The text is circled in red.
My code is as below:
from tkinter import *
from tkinter.ttk import Combobox
import win32com.client
root = Tk()
root.title('PM1 Digital Checklist')
root.geometry("400x400")
def open_excel():
if combo.get() == 'PPM8001':
myLabel = Label(root, text="Prime Mover Number Selected is:").pack()
myLabel = Label(root, text=combo.get()).pack()
excel = win32com.client.Dispatch("Excel.Application")
excel.Visible = True
file = excel.Workbooks.Open(r"/path/to/PPM8001.xlsx")
if combo.get() == 'PPM8002':
myLabel = Label(root, text="Prime Mover Number Selected is:").pack()
myLabel = Label(root, text=combo.get()).pack()
excel = win32com.client.Dispatch("Excel.Application")
excel.Visible = True
file = excel.Workbooks.Open(r"/path/to/PPM8002.xlsx")
if combo.get() == 'PPM8003':
myLabel = Label(root, text="Prime Mover Number Selected is:").pack()
myLabel = Label(root, text=combo.get()).pack()
excel = win32com.client.Dispatch("Excel.Application")
excel.Visible = True
file = excel.Workbooks.Open(r"/path/to/PPM8003.xlsx")
options = ['PPM8001','PPM8002','PPM8003']
v = list(options)
combo = Combobox(root, values = v, width =40)
combo.set("Select which Prime Mover number")
combo.pack()
button = Button(root, text = "Select", command = open_excel).pack()
root.mainloop()
The image is here:
There are 2 things to fix:
use
myLabel = Label(root, text="Prime Mover Number Selected is:")
myLabel.pack()
To actually put a Label instance into a variable
use
myLabel.destroy()
To get rid of it.
Hope that's helpful!
iam trying to make a phonebook using python and tkinter . I need to add new numbers to my phonebook

this is my code,what to do?
Variables in Python are not saved to disk, they only exist in memory (RAM) unless you explicitly save it there yourself.
You can either save to a file directly or, use a database instead.
See Here for using Pickle to do what you want.

ive currently been trying to build a GUI application in Tkinter that takes user input from an Entry and subsiquently populate a drop down menu. The probelm is that the OptionMenu keeps throwing:
Traceback (most recent call last):

mealOneButton = Button(root, text = "query database", command = GetEntry(mealOneString))
File "C:/Python34/food2GUIree.py", line 68, in GetEntry
meal = OptionMenu(root, '', *getMeal).pack()
TypeError: __init__() missing 1 required positional argument: 'value'
when i replace getMeal in:

formatted = x.get().split()##gets the entry and forms a list
getMeal = CsvLoadSearch(u, formatted)
meal = OptionMenu(root, '', *getMeal).pack()
with list = [1,2,3,4] or any other list it works fine. why is this?
