on the first occurrence of

, you mean True, not False :slightly_smiling_face:

  1. An alternative printList function:
def printList():
    print("", *myAgenda, "", sep="\n")

Notice that \n can be used instead of empty print() to display things on multiple lines
Learn more: print | iterable unpacking | escape sequences (e.g. \n)
2. For cross-compat and performance, use shutil.copyfile to copy files
3.

Ditto: use this instead

print(end="\033c")

Well, I searched for it on the internet, and I found that there are some logical issues with your code.
You can try this code to fix the error.

import os
import time
import random
import shutil  # Import the shutil module for file operations

# Check if the "calendar.txt" file exists
fileExists = os.path.isfile("calendar.txt")

try:
    myAgenda = []
    # Read data from "calendar.txt" if it exists
    with open("calendar.txt", "r") as f:
        myAgenda = eval(f.read())
except:
    fileExists = False


def printList():
    print()
    for item in myAgenda:
        print(item)
    print()


while True:
    DayPlanner = "Day-planner"
    print(f"\033[0;34m{DayPlanner:^35}")
    print()
    menu = input("Do you want to view, add, delete, remove or edit your to-do list?: ")
    print()
    if menu == "view":
        type1 = input("View all? (yes/no): ")
        if type1 == "yes":
            printList()
        type2 = input("View priority (high/low/medium): ")
        print()
        for item in myAgenda:
            if item["priority"] == type2:
                print(item)
    elif menu == "remove":
        item = input("What do you want to remove?: ")
        print()
        check = input("Are you sure you want to remove this? ")
        if check.lower() == "yes":
            for entry in myAgenda:
                if entry["item"] == item:
                    myAgenda.remove(entry)
                    os.system("clear")
                    time.sleep(2)
                    break
            else:
                print("Item does not exist in the list.")
        elif check.lower() == "no":
            pass
    elif menu == "add":
        item = input("What's next on the Agenda?: ")
        Due = input("When is this due?: ")
        priority = input("Priority type (high/low/medium): ")
        print()
        if not any(entry["item"] == item for entry in myAgenda):
            myAgenda.append({"item": item, "due_date": Due, "priority": priority})
            os.system("clear")
            time.sleep(2)
        else:
            print("Item already exists in the list.")
    elif menu == "edit":
        item = input("What do you want to edit?: ")
        print()
        for entry in myAgenda:
            if entry["item"] == item:
                new = input("What do you want to change it to?: ")
                print()

                os.system("clear")
                time.sleep(2)
                break
        else:
            print("Item does not exist in the list.")
    elif menu == "delete":
        break
# Create a backup if the file exists
if fileExists:
    try:
        os.mkdir("backups")
    except FileExistsError:
        pass
    name = f"Backups{random.randint(1, 1000000000000)}.txt"
    shutil.copy("calendar.txt", os.path.join("backups", name))
# Save the current data to "calendar.txt"
with open("calendar.txt", "w") as f:
    f.write(str(myAgenda))
