Im very new to python and im currently trying to create gui for a program that calculates the cost of parking. When running the code there are no errors but the program doesn't produce a label with the calculated cost. I also want it to produce a message asking for a valid input code if the letters C,D or V are not entered into the entry boxes. Any help in where im going wrong would be appreciated! I know the layout doesn't look good at the moment i'm going to go back and fix the placement of labels afterwards its more getting core basics of the code working that i'm struggling with.

You were calling functions inside def Vehicle(label_result, n1, n2) which isn't adding anything to your script so it preventing the result to display as a Label.No need to create function inside your if elif statement.check my edit on your function def Vehicle(label_result, n1, n2)

I am coding a 2048 game via pygame. below is the relevant section of my code:
class Data():
def __init__(self):
self.data = getnull()
self.score = 0
def updatesprites(self): # EXP
spritelist = [[],[],[],[]]
for count in range(4): # for row loop
for i in range(4): # per column loop
if self.data[count][i] != 0:
spritelist[count]+= newSprite(str(self.data[count] [i])+".png") # error occurs here
spritelist[count][i].move(15 + i*115, 15 + count*115)
showSprite(spritelist[count][i])
class newSprite(pygame.sprite.Sprite):
def __init__(self,filename):
pygame.sprite.Sprite.__init__(self)
self.images=[]
self.images.append(loadImage(filename))
self.image = pygame.Surface.copy(self.images[0])
self.currentImage = 0
self.rect=self.image.get_rect()
self.rect.topleft=(0,0)
self.mask = pygame.mask.from_surface(self.image)
self.angle = 0
def addImage(self, filename):
self.images.append(loadImage(filename))

What you are trying to do, is to add an element to a list.
This is done as follows:
li.append(element) # adds the element to the end of the list
Or in your case:
spritelist[count].append(newSprite(str(self.data[count][i]) + ".png"))
Another solution: You could create a new type, that lets you add elements the way you were trying to:
class UglyList(list):
def __iadd__(self, other):
self.append(other)
You'd need to change another line here:
spritelist = [UglyList() for i in range(4)]
I trying to create physics calculator using python tkinter but I find it quite difficult. I have done this calculator in Command line interface but I a bit different with tkinter. basically, I have 5 entry boxes and above each one of them a button. the user will insert values in three of them and should press the button on top of each unknown value to make the calculation and get the result. my main issue is how can I create a function that evaluates the inputs in my entry boxes and make the calculation then print the results inside the entry box. I made some coding but unfortunately the operation is not working due to few mistakes.
here is my coding part:
from Tkinter import *
import math
class calculator():
def is_positive_number(number): # validation function
if number <= 0:
return False
else :
return True
def value_of_time(prompt):
while True: # loop command for time
try:
valid = False
while not valid:
value = float((prompt))
if is_positive_number(value):
valid = True
return value
else :
valid = False
print ('I donot know what is happening')
except ValueError:
print("Oops, unfortunately this is a wrong input, please try again.")
#better try again... Return to the start of the loop
continue
else:
#value was successfully parsed!
#we're ready to exit the loop.
break
def input_of_box(prompt):
while True: # loop for initial velocity
try:
value = float(input(prompt))
return value
except ValueError:
print("Oops, we are you not typing a number, please try again.")
#better try again... Return to the start of the loop
continue
else:
#value was successfully parsed!
#we're ready to exit the loop.
break
# def minput(numberofinput):
if numberofinput == 1:
t = value_of_time("Enter the time that takes an object to accelerate in seconds:")
return
elif numberofinput == 2:
u = input_of_box("Enter the initial velocity in m/s:")
return
elif numberofinput == 2:
v = input_of_box("Enter the final velocity in m/s:")
return
def my_calculation(mvariables): # this function is to operate the calculation
if mvariables == 1:
a = (v-u) /(t)
mentery1 = a
return
elif mvariables == 2:
v = u + a*t
mentery2 = v
return
elif mvariables == 3:
u = a*t - v
mentery3 = t
elif mvariables == 4:
t = (v - u)/a
mentery3 = t
return
elif mvariables == 5:
s = (v**2-u**2)/2*a
mentery4 = s
else:
print ('there is an error')
cal = Tk()
cal.configure(background='sky blue')
a = StringVar()
u = StringVar()
v = StringVar()
t = StringVar()
s = StringVar()
cal.geometry('650x420+350+225')
cal.title('Main Menu')
# here we start greating buttons and entry boxes
m_label = Label(text='Calculator',fg = 'Navy', font=("Helvetica", 20,"bold italic"), bg='sky blue')
m_label.pack()
button1 = Button(cal,text='A',fg='white',bg='dark green',bd =3, width=4, command= lambda : my_calculation(1))
button1.place(x=92,y=210)
mentery1 = Entry(cal, textvariable = a ,width=10,bd =3)
mentery1.place(x=82,y=240)
button2 = Button(cal,text='U',fg='white',bg='dark green',bd =3, width=4, command= lambda : my_calculation(3))
button2.place(x=192,y=210)
mentery2 = Entry(cal, textvariable = u ,width=10,bd =3)
mentery2.place(x=182,y=240)
button3 = Button(cal,text='V',fg='white',bg='dark green',bd =3, width=4, command= lambda : my_calculation(2))
button3.place(x=292,y=210)
mentery3 = Entry(cal, textvariable = v ,width=10,bd =3)

button5 = Button(cal,text='S',fg='white',bg='dark green',bd =3, width=4,command= lambda : my_calculation(5))
button5.place(x=492,y=210)
mentery5 = Entry(cal, textvariable = s , width=10,bd =3)
mentery5.place(x=482,y=240)
# end of button commands
app = calculator()
app.mainloop()
For validating the input, do the following:
def returnValidatedInput(entry):
value = entry.get() # Get the text in the 'entry' widget
evaluation = eval(value) # Evaluate 'value'
return evaluation
And for inserting the answers into the entries (it's not called printing the answers into the entries):
def insertAnswer(entry, answer):
entry.delete(0, 'end') # Be sure the entry is empty, if it is not, clear it
entry.insert(END, str(answer)) # Insert the answer into the 'entry' widget.
This is my code and when i try to run it and use it by entering numbers into the entry fields, an attribute error occurs when i try to call on the entry variable. This is the message that appears:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python27\lib\lib-tk\Tkinter.py", line 1486, in call
return self.func(*args)

There's no quick fix for your code. It attempts to be object-oriented, but is doing so incorrectly. You need to properly define your methods, and should also adhere to PEP8 naming conventions -- specifically, methods and functions should start with a lowercase, and classes should start with an uppercase. Because you don't follow PEP8, and because of the odd way you use Prime_Gen to mean different things at different times, your code is incredibly hard to understand.
The crux of the problem is that inside OnGenButtonClick, Prime_Gen is not what you think it is. It is an instance of Prime_app_tk rather than the value that you set the local variable Prime_Gen to in Prime_Gen_Win. Thus, any attributes you assigned to the original Prime_Gen don't exist in this other Prime_Gen.
The reason is that the button is defined like this:
Genbutton = Button(..., command=self.OnGenButtonClick, ...)
In this context, self is the instance of Prime_app_tk, so that becomes the parameter passed to OnGenButtonClick. Inside that function you call the parameter Prime_Gen, in spite of the universal convention to name it self. This causes confusion in your code, because you also have a local variable named Prime_Gen in the code that creates the toplevel window.
So I am trying to multi process function F. Which is accessed by a button press with tkinter.
def f(x):
global doom,results,info
doom = doom + 1
if check(x) == True:
results.add(x)
info.append(get_column_number(x))
j.step(1)
texx = "1/"+doom
s.configure(text=texx)
root.update()
The function is called within a function like so:
def dojob():
index = ['URLS'...]
pool = Pool(processes=4)
s.configure(text="Shifting Workload to cores..")
root.update()
pool.map(f, index)
The button is inside root window.
I get the following error:
Exception in thread Thread-2:
Traceback (most recent call last):

You are leaking a tkinter object. Most likely because you are trying to update the interface from another process with the last line of f()
Update based on code
You have a name collision between your function f() and a variable f in your __main__ which gets assigned to your main window and causes the tkapp pickle error. Rename the function to def myfunc() or something. Also need to call pool.join() after pool.close()
