How to use gists for discussion of Python code
# Nostr posting: My first ever python script I wrote almost two years ago.
# This program will take user inputs and output the caloric intake required as stated in the insanity elite nutrition guide
print('Welcome to the Insanity Calorie calculaor \n');
# Step #1 Use the Harris Benedict Equation:
# First ask what the weight height, and age
print('Please answer each question \n')
weight = float(input("Please enter your weight in pounds: \n"))
dic = {}
for idx, char in enumerate (string):
if char! =' ':
if char not in dic:
dic [char] = [idx]
dic [char].append(idx)

Suggestions for NixOS developers
Offer nixos-enter after nixos-install as Per
After one has installed NixOS as per the instructions at:
consider prompting the user and offering to perform nixos-enter to chroot into /mnt.
This can allow the new user to explore their new installation before reboot; but it also teaches them how they might later
use the nix-enter command for rescue perposes.
Of course getting value of this is in providing enough information in the prompt to inform the user of the option,
offer them more info, and showing them what it's doing (much as the web page is already doing; but presented there

Example of a naïve decorator function
def prefixer(fn, prefix):
'''Return a wrapper which prefix first (string) argument with prefix'''
def wrapper(output, *args, **kwargs):
output = '%s%s' % (prefix, output)
return fn(output, *args, **kwargs)
return wrapper
## Example of a decorator WITHOUT using the @wrapper syntactic sugar
## (to save ref to print if we want to use it later: old_print = print)
