# note: everything below needs Python 3.13 or newer. The bank runs
# Python 3.12, where this is not there yet.

# *** before: ***
# the prompt of 3.12 was a plain one: no colours and no block editing. A
# multi line block could not be corrected after its first line, an
# indented block broke when pasted, and leaving took a call:
#
#   >>> def greet(name):
#   ...     print("hi", name)
#   ...
#   >>> exit
#   Use exit() or Ctrl-D (i.e. EOF) to exit
#   >>> exit()

# *** in version 3.13: ***
# the prompt is a new one, written in python and taken from PyPy:
#
#   >>> def greet(name):        # the WHOLE block is edited with the arrows,
#   ...     print("hi", name)   # and history walks over blocks, not lines
#   ...
#   >>> exit                    # leaves at once, without a call
#
#   F1  opens the help of the prompt itself
#   F2  shows the history without the >>> and ... marks, ready to copy
#   F3  turns on paste mode, so an indented block pastes as it is
#
# tracebacks and prompts are coloured; PYTHON_BASIC_REPL=1 brings the old
# prompt back, and NO_COLOR=1 or PYTHON_COLORS=0 removes the colours


def greet(name):
    print("hi", name)


greet("Ann")
