As a follow up of the "Bash: Easy help print", lets do the same thing. So I will just copy the whole text and replace what needs replacing...
Ok, lets create a single line of python that will handle the -h option and print something.
First, what to print? I usually add some comments on the start of the file, so lets print that. Example script:
#!/bin/env python3 # # This is the doc of the script # the line that we will add code of script
Lets go step by step. We need to print the file it self:
h = open(args, 'r').read() print(h)
Skip the first line (lets skip the read):
Go until you find the first empty line:
Remove the # fro the start of the line:
Finally, we check if the -h is the first argument, print the thing and exit:
if '-h' in args: h = open(args, 'r').read(); print(h[h.index('\n')+1:h.index('\n\n')].replace('#','')); exit()
