carriage return prints

*When having a function run a long time, we want to follow its progress, without spamming the output.
Use {python} '\r' in a print function. It stands for carriage return, (Schreibmaschine) which goes back to the start of the first line and "overwrites" the current line.

for epoch in range(epochs):
	print(f"epoch: {epoch} / {epochs}", end="\r") # this line will overwrite the previous print!

this does a "carriage return", meaning we go back to the start of the line and overwrite that line. If you have a \n in your string, then the carriage return won't work as expected.

limit the amount of decimal places

{python}print(f"variable: {variable:.2f}") # will only show 2 decimal places.
