I am currently making a hangman game and I have a global variable that indicates which part of the hangman to draw. The problem is that I need to change the value of this variable (drawRate) within a function as I will need it in a different function later on but python will not let me do this. Is there any way I can work around this problem?
import tkinter as tk
import turtle
import string
from functools import partial
from draw_hangman import drawHangman
word = 'hello'
shown_text = list('-'*len(word))
draw = drawHangman()
drawRate = 0
def whenPressed(button, text):
button.config(state = 'disabled')
ind = []
local_word = list(word)
for i in local_word :
if i == text:
trash = local_word.index(i)
ind.append(trash)
local_word.pop(trash)
local_word.insert(trash, '-')
if len(ind) != 0:
for i in ind:
shown_text.pop(i)
shown_text.insert(i, text)
lab.config(text = ''.join(shown_text))
for i in shown_text:
if i == '-':
trash = True
if trash != True:
print('You Won!')
else:
trash = draw[drawRate]
exec(trash)
drawRate+=1
root = tk.Tk()
t = turtle.Turtle()
alphabet = list(string.ascii_lowercase)
lab = tk.Label(root, text = '-'*len(word), font = (None, 15), width = 30)
lab.grid(row = 0, columnspan = 13)
for i in alphabet:
btn = tk.Button(root, text=i)
command = partial(whenPressed, btn, i)
btn.config(command=command)
row = (alphabet.index(i) // 13)+1
column = alphabet.index(i) % 13
btn.grid(row=row, column=column, sticky="news")
The variable draw is a list with the commands that draws the hangman figure:
draw = [
'''t.penup()
t.fd(200)
t.rt(90)
t.fd(200)''',
'''t.down()
t.lt(270)
t.fd(400)''',
'''t.rt(90)
t.fd(400)''',
'''t.rt(90)
t.fd(300)''',
'''t.rt(90)
t.fd(75)
t.dot(75)''',
't.fd(100)',
'''t.lt(90)
t.fd(60)''',
'''t.back(120)
t.fd(60)
t.rt(90)''',
'''t.fd(75)
t.lt(30)
t.fd(100)''',
'''t.back(100)
t.rt(60)
t.fd(100)''']
You have to declare this variable as global in the whenPressed() function like this:
def whenPressed(button, text):
global drawRate
...
I am a newbie, forgive me in advance if this is incorrect but can you not declare/bring in your global variable at the start of the function: global drawRate
def whenPressed(button, text):
global drawRate
button.config(state = 'disabled')
ind = []
local_word = list(word)
for i in local_word :
if i == text:
trash = local_word.index(i)
ind.append(trash)
local_word.pop(trash)
local_word.insert(trash, '-')
if len(ind) != 0:
for i in ind:
shown_text.pop(i)
shown_text.insert(i, text)
lab.config(text = ''.join(shown_text))
for i in shown_text:
if i == '-':
trash = True
if trash != True:
print('You Won!')
else:
trash = draw[drawRate]
exec(trash)
drawRate+=1
Try defining drawRate as global at the top of your whenPressed function
like
import turtle
import string
from functools import partial
from draw_hangman import drawHangman
word = 'hello'
shown_text = list('-'*len(word))
draw = drawHangman()
drawRate = 0
def whenPressed(button, text):
global drawRate
button.config(state = 'disabled')
ind = []
local_word = list(word)
for i in local_word :
if i == text:
trash = local_word.index(i)
ind.append(trash)
local_word.pop(trash)
local_word.insert(trash, '-')
if len(ind) != 0:
for i in ind:
shown_text.pop(i)
shown_text.insert(i, text)
lab.config(text = ''.join(shown_text))
for i in shown_text:
if i == '-':
trash = True
if trash != True:
print('You Won!')
else:
trash = draw[drawRate]
exec(trash)
drawRate+=1
root = tk.Tk()
t = turtle.Turtle()
alphabet = list(string.ascii_lowercase)
lab = tk.Label(root, text = '-'*len(word), font = (None, 15), width = 30)
lab.grid(row = 0, columnspan = 13)
for i in alphabet:
btn = tk.Button(root, text=i)
command = partial(whenPressed, btn, i)
btn.config(command=command)
row = (alphabet.index(i) // 13)+1
column = alphabet.index(i) % 13
btn.grid(row=row, column=column, sticky="news"```

I am attempting to make Minesweeper in python using Tkinter. I have completed all of the initial logic but I am having trouble with the squares with zero surrounding bombs. The program is meant to open all of the surrounding squares when a square with zero surrounding bombs is clicked. The problem here is that it somehow creates an infinite loop. This may be due to the fact that I am calling the function click multiple times using a for loop but I am not sure if this is correct or how to fix it.
My code so far:
import tkinter as tk
from random import choices
from math import floor
##•
def openSurroundings(i):
trash = [i+1, i+8, i+9, i+10, i-1, i-8, i-9, i-10]
for a in trash:
if a<81:
click(floor(a/9), a-((a//9)*9))
def click(row, col):
text = numbers[row][col]
widget = buttons[row][col]
widget.grid_forget()
clickSurrounding = False
if text == 0:
text = ''
clickSurrounding = True
lab = tk.Label(window, text = text, height = 2, width = 5)
lab.grid(row = row, column = col)
if clickSurrounding == True:
openSurroundings((row*9)+col)
def placeBombs():
global widgets, bombs
numOfBombs = 10
widgets = list(range(1, (len(buttons)**2)+1))
bombs = choices(widgets, k = numOfBombs)
def findNumbers():
global numbers
numbers = []
lis_num = []
for i in widgets:
if i in bombs:
lis_num.append('•')
continue
else:
trash = [i+1, i+8, i+9, i+10, i-1, i-8, i-9, i-10]
num = 0
for a in trash:
if a > 0 and a in bombs:
num += 1
lis_num.append(num)
for i in range(0, len(lis_num), 9):
numbers.append(lis_num[i:i + 9])
window = tk.Tk()
window.title('Minesweeper')
sideLen = 9
row_index = 0
cell_index = 0
buttons = []
while row_index != sideLen:
button_row = []
while cell_index != sideLen:
button = tk.Button(window, width=5, height = 2, command=lambda row_index=row_index, cell_index=cell_index: click(row_index, cell_index))
button_row.append(button)
button.grid(row=row_index, column=cell_index)
cell_index += 1
buttons.append(button_row)
cell_index = 0
row_index += 1
placeBombs()
findNumbers()

Short explanation of the code: It's a code to read out sensor data from a text file -
GetValue().
If the Data is Null it'll read out again - WithoutNull().
The Data is then splitted into data and timestamp (cause it has the format val1, val2, val3, val4, time) - UebergabeWert.
Then the maxima, minima and average of the data will be measured - MinutenWert()
After this, the values are set as labels and go their way into Tkinter - UebergabeTkinter()
The Tkinter build is mainly in Try:
What I wanted to do there, is to implement a graph to Tkinter, but because of the fast changing values it got tremendously slow so i decided to put the graph build in a thread and run it parallel to Tkinter. Unfortunately, it doesn't seem to work and I don't know why
Any suggestions?
I am a fairly novice programmer and through coffee, google, and an immense loss of hair and fingernails have managed to write a very messy code. I am asking anyone to help me simplify the code if possible.

I'm creating a GUI using Tkinter that is used to collect information from a user. I need to validate:
First and Last name only contain letters, apostrophes, and dashes

I have a couple questions.
Starting from def validFirst(self), how do I validate the different entry fields? I keep getting NameError: name "asdf" is not defined, SyntaxError: unexpected EOF while parsing, and TypeError: 'int' object is not subscriptable when I modify the code and I'm still stuck on validFirst(self).
I have a set of labels in column 3 reserved for error messages: errorLblFirst = Label(window, text = " ", fg = "red").grid(row = 1, column = 3). Is it possible to set it to " * Invalid Entry", fg = "red" when the validation for that entry fails? Is there another way to get error messages to show?
Thanks in advance for the input!
Edit: I updated to my latest code. Most of the validation works now except for validBday and validEmail if you could check it out.
errorLblFirst = Label(...).grid(...)
This way you assign result of grid() to errorLblFirst but grid() always returns None
Always do it this way
errorLblFirst = Label(...)
errorLblFirst.grid(...)
And now you can do (for example)
errorLblFirst["text"] = " * Invalid Entry"
errorLblFirst["fg"] = "red"
EDIT:
You forgot len() in for i in range(first): in validFirst()
And you don't need eval().
(You got the same problem in validPhone())
F = 0
fName = True
first = self.firstName.get() # without eval()
for i in range(len(first)): # len()
if first[i].isdigit():
F += 1
if F > 0:
return False
else:
return fName
return fName
but you could do this shorter
for letter in self.firstName.get():
if letter.isdigit():
return False
return True
if you need only letters (no space, commas, etc.) you could do this
return self.firstName.get().isalpha()
EDIT:
I see First Name can have apostrophes, and dashes
for letter in self.firstName.get():
if not letter.isalpha() and letter not in "'-":
return False
return True
EDIT: problem with self.phone and StringVar
self.phone is StringVar() - not string
but StringVar() has .get() to get string
for number in range(len( self.phone.get() )):
By the way: you can do for loop more pythonic - without range(len())
for char in self.phone.get():
if char.isdigit():
EDIT: problem with validEmail() and validBday()
Email validation needs more if.
For example you could add
email = self.email.get()
if '#' not in email and '.' not in email::
print( 'email needs # and . at the same time')
but '.#' will pass this test :/
Real email validation is more complicated.
See valid email examples: https://fightingforalostcause.net/content/misc/2006/compare-email-regex.php
self.bday is StringVar - use self.bday.get() in place of str(self.bday)
EDIT:
def validPhone(self):
D = 0
for number in self.phone.get():
if number.isdigit():
D += 1
# outside
if D == 10:
return True
else:
self.errorLblPhone["text"] = " * Must be 10-digit phone number without spaces"
return False
return True
or even
def validPhone(self):
# remove previous error message
self.errorLblPhone["text"] = ""
D = 0
for number in self.phone.get():
if number.isdigit():
D += 1
if D != 10:
self.errorLblPhone["text"] = " * Must be 10-digit phone number without spaces"
return False
return True
If number can have only 10 digits (no space, no - , etc):
def validPhone(self):
# remove previous error message
self.errorLblPhone["text"] = ""
D = True
for number in self.phone.get():
if not number.isdigit():
D = False
break
if not D or len(number) != 10:
self.errorLblPhone["text"] = " * Must be 10-digit phone number without spaces"
return False
return True
what i have is a window that opens up and it has a list box. this is created using one class. when i click the search button and results are found using a different class, i want the list box to update without having to open up another window. below is my code so far\n

any help would be great

The biggest problem in your code is that you're creating multiple instances of Tk. Tkinter simply isn't designed to work that way. You should only ever create a single instance of Tk. If you need additional windows, create instances of Toplevel.
Also, you need to call the mainloop function of this instance of Tk exactly once. Without it, your GUI will not work.
If you want to update a listbox in another class than where it was created, the concept is pretty simple: if A needs to update B, A needs a reference to B. So, either pass in a reference to the listbox when you create the other class, or give the other class a method you can call where you pass in the reference to the listbox after it was created.
