I am an electrical engineer and I am new to Python programming.
I want to write a Python program for three phase transformer calculator. The program is very simple, it does just a few algebraic operation; I wrote simple python code without GUI and it worked very fine. So I decided to make the same program using Tkinter module to give a GUI to my application. I had some error and I read a lot of questions and asked many questions on this community, but I am not able to solve it. I am not able to trace the cause of the error. The code is:

The first kind of error I had was a ValueError: could not convert string to float. I read this could happen because at the start time, the entry widgets are empty so python can convert it to float. So I added try/except block. Now when I start the program, it prints an error message in except block (I can't understand this: the calcola function is associated to the calculate button, but it seems to run the function without button press, at start time) then don't happen anything else, though writing number in entry box and pressing calculate button. What I suspect is that the way I am using function is wrong (syntax or something else). If anyone can help me, I'd really appreciate.
Sorry for bad English. Thank you very much.

when passing parameters through your function if it is called by a tkinter button you should always use the lambda statement like this: Button(finestra,text='Calcola',command=lambda: calcola(paramaters..) or the function will be called just once when the program starts.

I'm working on the PW Crack Level4 in the PicoCTF General Skills section. I'm very new to python and CTF's in general. The challenge is to find the right pw from the included list of 100 possibles. I could have, by now, simply entered each one, lol, but that's not the point I think. So I am trying to modify the code to iterate through the list of pw's and pass each one to the part of the code that checks it.
That's where I'm stuck. The for loop seems to run through the list without passing each pw to the part of the code that should check it... I feel like the answer is on the tip of my tongue. But I'm too new to see it.
Here's my code

I'm not too experienced myself, but I think I know what you're doing wrong. I'll try to give you a small tip that will probably help you solve the problem without giving you the answer full out.
I think where you're going wrong is that you're still asking for input. Since you're comparing a list of possible passwords to the actual possible password, you don't need to ask for input anywhere in your code.
I hope this helps you out!
SO I stumbled upon the answer.... it appears to be a indent error (sorry, I don't fully grasp python). But once I properly indented my modified code I got the answer!

*I wanted to bind platform_id drop combobox to teh combobox_b so taht if cpu is selected in platform_id_drop, then cpu frequencies must be listed otherwise gpu frequencies must be listed. I am using while loop to create a number of rows based on input we are giving and used dictionary to store respective columns. I am able to get only fo rone set of row i.e frequencies are display oly for one row but not for other rows. Having Problem with bind function. Please help me with this.

so i have the code down below
import requests
import json
with open("forex_rates.json", "r") as file:
rate = json.load(file)
nrate = rate
Base = input("enter your base currency: ")
if Base not in rate["rates"]:
print("That's not a valid currency...")
Base = input("enter your base currency: ")
with open("forex_rates.json", "r") as file:
nrate["base"] = Base
for i in rate["rates"]:
nrate["rates"][i] = rate["rates"].get(i) / rate["rates"].get(Base)
print(nrate["rates"])
I'm trying to make a program that converts different currencies, for example:
1 EUR --> 1.18 USD
and in order to do this I have to edit the forex rates everytime depending on the base value
when i finished up the code i ran t and it worked all fine and it converted all values until it hit the same value in the forex value file
like if i convert from USD it will change all currency values depending on USD but when it hits the USD in the file the loop breaks
i tried for so long 'till i tried moving USD to the very bottom of the file as there is nothing after it to break. and it worked but that's for USD only.
when i change the base value inside the program it breaks again
for people saying the code isn't even finished i'd say that i almost finished this part of the program the converting part which i believe the most difficult and any other code left is only the GUI and some multiplying math
and i'll list the forex data below
#sorry if it's too big

Is there a way to add all values together but not getting them? This is for my school menu project. Any help appreciated.
Note: The values are in KJs for food. So far I have all the values but they are just put there, e.g. 11801800, but not adding it up. I used r.get()+v.get() but they don't actually add the values up.
They do add up. Your problem is that r.get() returns a string, not an integer. First convert them, then sum up.
int(r.get()) + int(v.get())
I am writing an application whose purpose is to create a graph from a journal dataset. The dataset was a xml file which was parsed in order to extract leaf data. Using this list I wrote a py2neo script to create the graph. The file is attached to this message.
As the script was processed an exception was raised:
The debugged program raised the exception unhandled TypeError

File: /usr/lib/python2.7/site-packages/py2neo-1.5.1-py2.7.egg/py2neo/neo4j.py, Line: 472
I don't know how to handle this. I think that the code is syntactically correct...but...
I dont know if I shoud post the entire code here, so the code is at: https://gist.github.com/herlimenezes/6867518

Any help?
I have already fixed it, thanks to Nigel Small. I made a mistake as I wrote the line on creating relationships. I typed:
publicacao = graph_db.get_or_create_relationships(titulo_nodes[i], "publicado_em", dataPub_nodes[i])
and it must to be:
publicacao = graph_db.get_or_create_relationships((titulo_nodes[i], "publicado_em", dataPub_nodes[i]))
By the way, there is also another coding error:
keyword_nodes.append(keyword_index.get_or_create("keyword", pedacos[i][3][k]))
must be
keyword_nodes.append(keyword_index.get_or_create("keyword", pedacos[i][3][k], {"keyword":pedacos[i][3][k]}))
