Creating Newlines

Creating newlines prevents text from being overwritten.

Writing to Screen

multicarriage.MultiCarriage.write("first text", 2, clearline=True)

# example of auto updating epoch and datetime
import multicarriage
import time
import datetime

# creating newlines to avoid overwriting current text
multicarriage.MultiCarriage.create_newline(3)
while True:
    try:
        timestamp = time.time()
        date = datetime.datetime.fromtimestamp(timestamp)
        multicarriage.MultiCarriage.write(f"epoch: {timestamp}", 3, clearline=True, flushtxt=True)
        multicarriage.MultiCarriage.write(f"epoch (s): {timestamp//1}", 2, clearline=True, flushtxt=True)
        multicarriage.MultiCarriage.write(f"datetime string: {date}", 1, clearline=True, flushtxt=True)
