This is my current code and it displays in a window but literally prints it the way I've typed it (obviously). But is there a way to write these so they are displayed as powers/exponents?

Unicode has superscript numerals, arithmetic operators, and some letters in the BMP, which is supported by tcl/tk. See Wikipedia. Within those constraints, and given a supporting font, the answer is yes. On Windows, running from IDLE, the following works nicely and looks nice, though I would want the tk font larger to see the superscript easily with my eyes.
import tkinter as tk
root = tk.Tk()
# "4x^4 + 3x^1/2"
t1 = "4x\u2074 + 3x\u207b\u00b2" # \u excapes, if needed
t2 = "4x⁴ + 3x⁻²"
label = tk.Label(root, text=t2)
label.pack()

I'm attempting to create a GUI for astrophotography, and am trying to add a function that would allow choosing a specific directory for files.

I have tried using lambda functions, the partial function, and have tried seeing if it is just an issue with the my function itself. Regardless of what the uploadFlats actually does, I'm given this same error. I have tried sending in multiple different types of variables, however they are all consistently ignored.

Setting background color of a tkinter ttk frame
(3 answers)
Closed 3 years ago.
I want to change the background of my ttk form (ceasar code script) to the color I have in my window = #FEFB22
I want to change the white "box" color to #FEFB22 click to see image !
from tkinter import *
from tkinter import ttk
# variables

enc_dec_text = ttk.Entry(root.frame_header, width=110)

cipher_shift_menu = StringVar()
Spinbox(root.frame_header,from_=1, to=25, textvariable=cipher_shift_menu).grid(row=1, column=1)

for character in stringtoencrypt:

newposition = position+ciphershift
if character in letters:
stringencrypted = stringencrypted + letters[newposition]

#add image
width = 200
lenght = 200
image = PhotoImage(file="logort.png")
#bouton image
button = Button(root, image=image, bg='#FEFB22', bd=0, relief=SUNKEN)
button.pack()
# boutous
encrypt_button = ttk.Button(root.frame_header,text='Encrypter',command = lambda: encrypt_text()).grid(row=3,column=0)
decrypt_button = ttk.Button(root.frame_header,text='Decrypter',command = lambda: decrypt_text()).grid(row=3,column=1)
#bouton q
# uitter
bouton_quitter = Button(root, text="Quitter !", command=root.quit, font=("Courrier", 20), bg='#000000', fg='#FEFB22')
bouton_quitter.pack(side=BOTTOM)
root.frame_header.pack()
root.mainloop()
You can use ttk.Style to change the frame background color:
s = ttk.Style()
s.configure('My.TFrame', background='#FEFB22')
root.frame_header = ttk.Frame(root, style='My.TFrame')

I'm exactly sure on how to upload the gif file with this code.
The error message is telling you what's wrong. If you have already used one geometry manager within a widget you cannot use another.
e.g. - You cannot use both pack and grid within a frame. You must use one or the other.
You could make another widget and then use the seperate geometry manager within this widget but you would have to use the original manager to place it within the master widget.
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
Address
Phone number has the correct number of digits
Valid birthday (Feb 31 doesn't exist and birth year between 1900 and 2014)
Email address contains '#' and '.'
Here is my code:

messagesMenu.add_command(label = "Send a Birthday Greeting", command = self.bdayGreeting)

# Create another menu option

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
