WebJun 17, 2016 · Those functions are located in the bisect module: bisect.bisect_left(a, x, lo=0, hi=len(a)) is the analog of std::lower_bound(). bisect.bisect_right(a, x, lo=0, hi=len(a)) is the analog of std::upper_bound(). Note: there is also a function bisect() which is an alias for bisect_right(). http://www.duoduokou.com/java/31710549297763131807.html
