# Prerequisite section
# What this code does is compile two Cython modules, rolling and expanding, using setuptools and Cython,
# and builds them as binary expansion modules that can be imported directly into Python.
# Since pyproject.toml can't do that, we compile it here.

# pywinpty as a dependency of jupyter on windows, if you use pip install pywinpty installation,
# will first download the tar.gz file, and then locally compiled and installed,
# this will lead to some unnecessary trouble, so we choose to install the compiled whl file, to avoid trouble.

# Check code with flake8.
# The following flake8 error codes were ignored:

# 	Description: We have used black to limit the length of each line to 120.
# F541 f-string is missing placeholders
# 	Description: The same thing is done when using pylint for detection.
# E266 too many leading '#' for block comment
# 	Description: To make the code more readable, a lot of "#" is used.
#         This error code appears centrally in:
# 			qlib/backtest/executor.py
# 			qlib/data/ops.py
# 			qlib/utils/__init__.py
# E402 module level import not at top of file
# 	Description: There are times when module level import is not available at the top of the file.
# W503 line break before binary operator
# 	Description: Since black formats the length of each line of code, it has to perform a line break when a line of arithmetic is too long.
# E731 do not assign a lambda expression, use a def
# 	Description: Restricts the use of lambda expressions, but at some point lambda expressions are required.
# E203 whitespace before ':'
# 	Description: If there is whitespace before ":", it cannot pass the black check.
