You are looking for a dictionary with function references maybe?
menu_options = {
'c':io_celsius_to_fahrenheit,
'f':io_fahrenheit_to_celsisus,
'q':print_options
}
The io versions of the functions would wrap the conversion functions to get
the input and print the output.
choice = "foobar"
while choice != 'q':
try:
menu_options[choice]()
except KeyError:
# else code here
choice = raw_input("option:")
