Remove the hassle from making Secret Santa gift giving assignments with Python 3. This short program uses Standard Library modules like csv, random, and smtplib to read a file, create random Secret Santa assignments, then prepare & send email notifications to each participant.

secret_santa.py

# To start, set up a Google form that collects
# first name, last name, and email address from participants,
# then export as a CSV file and store it in the same
# directory as this program
# also, enable less secure apps in gmail before running
# https://support.google.com/accounts/answer/6010255?hl=en

import csv
import smtplib
from random import shuffle
from email.mime.text import MIMEText

# function we'll use later on for sending notifications
def send_gmail(from_addr, password, to_addr, subject, body):
    """prepares and sends gmail"""
    msg = MIMEText(body)
    msg["Subject"] = subject
    msg["From"] = from_addr
    msg["To"] = to_addr
    s = smtplib.SMTP("smtp.gmail.com: 587")
    s.ehlo()
    s.starttls()
    s.login(from_addr, password)
    s.send_message(msg)
    s.quit()

# create empty containers
participants= list()
pairs = dict()

# read through imported participant CSV file
# row[0] = fname, row[1] = lname, row[2] = email address
with open("names.csv", "r") as f:
    csv_reader = csv.reader(f)
    for row in csv_reader:
        participants.append((row[0].strip() + " "
                             + row[1].strip(), row[2].strip())) #(fname lname, email)

shuffle(participants) # participants is a list of tuples, fyi

# iterate over shuffled participants to create key, value pairs
for i in range(len(participants)):
    pairs[participants[i]] = participants[(i+1) % len(participants)]

# write Secret Santa pairings to new CSV file for future reference
with open("match_list.csv", "w", newline="") as f:
    csv_writer = csv.writer(f)
    for key,value in pairs.items():
        csv_writer.writerow([key[0], key[1],"---------->", value[0], value[1]])

# send email notification to each Secret Santa participant
for key, value in pairs.items():

    key_first_name = key.split()[0]

    body = f"Hi {key_first_name}!\n\n" \
           f"Thank you for participating in this year's gift exchange. " \
           f"I have randomly assigned you to give a gift to:\n\n" \
           f"{value[0]}\n{value[1]}\n\n" \
           f"I recommend spending no more than $10. " \
           f"Thanks again for participating, and happy holidays!\n\n" \
           f"Cheers,\n\n" \
           f"(your name)"

    try:
        send_gmail("#your gmail", "#your password",
               key[1], "It's Secret Santa Time!", body)
    except Exception as e:
        print(f"There was a problem sending an email to: {value[1]}")
        print(e)
        print("\n***\n")
