Go CrossCompile

Code, Go

Crosscompile under GoLang

Python is cool and everybody like it, but i also like the Concept of writing some Code, compile it for different Platforms and run it everywhere. Google’s Go Language got the possiblity to compile it for multiple Architectures and Operating Systems at the same time. Why not give a try … ?

Little Hello World

package main

import (

func main() {
    s := "world"

    if len(os.Args) > 1 {
        s = os.Args[1]
    }

    fmt.Printf("Hello, %v!", s)
    fmt.Println("")

    if s == "fail" {
        os.Exit(30)

Little Mail Validator in Python

Code, Python

wrote a little Mail Adresse Validator in Python. use it, modify it, like it … best practice for python is to use a virtual env like Poetry (or virtualenv) and add the “email-validator” module like this:

poetry add email-validator

Code

few lines of code …

#!/usr/bin/env python3

from email_validator import validate_email, EmailNotValidError

ok=[]
nok=[]

emails = [
        "my+address@mydomain.tld", "hans@dampf.ch", "gott@welt.net",
        "adsf@asdf.com", "asf.asdf", "franz!mueller@abc.com", "asdf@asdf.adf"
        ]

print ("\nMy Little Mail Validator\n")

for email in emails:

    try:
        # Validate.
        valid = validate_email(email)

        # Update with the n
        email = valid.email

        # Append to List
        ok.append(email)

    except EmailNotValidError as e:

        # email is not valid, exception message is human-readable
        nok.append(str(e))


print ("*** Mail ok ***")
for item in ok:
    print("ok: ", item)

print ("\n*** Mail NOT ok ***")
for item in nok:
    print("NOK:", item,"!")

print()

Run

just run and enjoy …
