• What is your OS?
• Do you want a GUI calculator or would you be content to launch a window in which a line by line calculator runs?
• Have you looked for solved threads at DaniWeb? Near the top right corner of the page Type Python Calculator in the SEARCH box
• Have you tried Google?

You can design rather simple calculator using the Python function eval():

# simple calculator using Python function eval()
# improvements:  
# safeguard eval(), error check math expression
# loop for more calculations and so on
#
# importing math functions allows you to enter sin(1.6), pi  etc.

from math import *

# for Python3 use input()
exp = raw_input("Enter math expression (eg. 12*12-4): ")
print(eval(exp))
