Here\'s my problem: I\'m running the code in this example. I have Python 2.7 and 3 installed on my RaspberryPi but I have checked and double-checked, and I am running the c

Answer 1

rewritten script that runs on python 3.4.0 onwards

def add():
        print ("Enter the two numbers to Add")
        A=int(input("Enter A: "))
        B=int(input("Enter B: "))
        return A + B 

def sub():
        print ("Enter the two numbers to Subtract")
        A=int(input("Enter A: "))
        B=int(input("Enter B: "))
        return A - B

def mul():
        print ("Enter the two numbers to Multiply")
        A=int(input("Enter A: "))
        B=int(input("Enter B: "))
        return A * B

def div():
        print ("Enter the two number to Divide")
        A=float(input("Enter A: "))
        B=float(input("Enter B: "))
        return A / B

print ("1: ADDITION")
print ("2: SUBTRACTION")
print ("3: MULTIPLICATION")
print ("4: DIVISION")
print ("0: QUIT")

while True:

    CHOICE = int(input("ENTER THE CORRESPONDING NUMBER FOR CALCULATION ")) 

    if CHOICE == 1: 
        print ('ADDING TWO NUMBERS:')
        print (add())

    elif CHOICE == 2:
        print ('SUBTRACTING TWO NUMBERS')
        print (sub())

    elif CHOICE == 3:
        print ('MULTIPLYING TWO NUMBERS')
        print (mul())

    elif CHOICE == 4:
        print ("DIVIDEING TWO NUMBERS")
        print (div())

    elif CHOICE == 0:
        exit()
    else:
        print ("The value Enter value from 1-4")

Answer 2

you have imported wrong module use: import Tkinter

Answer 3

Another workaround would be the following:

try:
    import tkinter
except:
    import Tkinter as tkinter

This way you would always have the module tkinter available and depending on the Python version your program loads tkinter or Tkinter.

Answer 4

I was facing the same problem with matplotlib.pyplot (python 2.7+) in my CentOs. I solved the problem by just installing the tkinter. sudo yum install tkinter. Hope this can help you.

Answer 5

Maybe I can help you on how to remove the error.

here are two thoughts:

1) you use python 2.xx and have installed the python 3 pwm module (Tkinter was renamed to tkinter from Python 2 to 3)

2) you do the following before the import and hope it helps:

#import tkinter
#Traceback (most recent call last):
#  File "<pyshell#11>", line 1, in <module>
#    import tkinter
#ImportError: No module named tkinter

import sys, Tkinter
sys.modules['tkinter'] = Tkinter # put the module where python looks first for modules
#import tkinter # now works!
