python - 比较 int 值

Question

为什么我的代码不允许我比较这 4 个整数——它只是不返回任何值？我做错了什么——只是一个初学者

def isinRange(exonStartPos,   exonEndPos,  ChromListStartPos,  ChromListEndPos):
    inRange  = False
    if exonStartPos < ChromListStartPos & exonEndPos < ChromListEndPos:
        returnList = [inRange, 0 , 0]
        return returnList
    if exonStartPos > ChromListEndPos & exonEndPos> ChromListEndPos:
        returnList = [inRange, 0 , 0]
        return returnList
    if exonStartPos < ChromListStartPos & exonEndPos < ChromListEndPos:
        inRange = True
        returnList = [inRange, ChromListStartPos, exonEndPos]
        return returnList
    if exonStartPos > ChromListStartPos & exonEndPos > ChromListEndPos:
        inRange = True
        returnList = [inRange, exonStartPos, ChromListEndPos]
        return returnList
    if exonStartPos == ChromListStartPos & exonEndPos <= ChromListEndPos:
        inRange = True
        returnList = [inRange, exonStartPos, exonEndPos]
        return returnList
    if exonStartPos >= ChromListStartPos & exonEndPos == ChromListEndPos:
        inRange = True
        returnList= [inRange, exonStartPos, exonEndPos]
        return returnList


if __name__ == '__main__':
    ChromListRange = isinRange(665973, 666002, 745554,752391)
    print ChromListRange[0]

我相信您需要将 & 更改为 and。它对我有用。
