Problem: Email a Birthday person on his/her Birthday

Solutions

Update the birthdays.csv => Go into the birthdays.csv and edit it.
Check if today matches a birthday in the birthdays.csv

# Use the datetime module to obtain the current day of the week
now = dt.datetime.now()
today = (now.month, now.day)

df = pd.read_csv("birthdays.csv")
# Use dictionary comprehension to create a dictionary from birthday.csv
birthdays_dict = {(df_row.month, df_row.day): df_row for (index, df_row) in df.iterrows()}

If step 2 is true, pick a random letter from letter templates folder

if today in birthdays_dict:
    file_path = f"letter_templates/letter_{random.randint(1,3)}.txt"
    birthday_person = birthdays_dict[today]["name"]
    birthday_email = birthdays_dict[today]["email"]

    with open(file_path) as letter:
        contents = letter.read()
        contents_with_name = contents.replace("[NAME]", birthday_person)

Send the letter generated in step 3 to that person's email address

# ***WARNING***:
# Make sure you use a dummy email account to test this out!
my_email = "YOUR_EMAIL"
password = "YOUR_EMAIL_PASSWORD"

with smtplib.SMTP("YOUR_EMAIL_PROVIDERS_SMTP_ADDRESS", port=587) as connection:
    connection.starttls()
    connection.login(user=my_email, password=password)
    # Write messages
    connection.sendmail(
        from_addr=my_email,
        to_addrs=birthday_email,
        msg=f"Subject:Happy Birthday, {birthday_person}!\n\n{contents_with_name}"
    )

Lessons

Review the dictionary comprehension:

From a list: new_dict = {new_key:new_val for itme in list if test}
From a dictionary: new_dict = {new_key:new_val for (key, val) in dict.items() if test}
