Note: The result may be very large, so you need to return a string instead of an integer. python code: class Solution: # @param num, a list of integers # @return a string def largestNumber(self, num): num=[str(x) for x in num] num.sort(cmp=lambda x, y: cmp(y+x, x+y))...

这一切基于假设:Python 中的标准扩展module 是不会在运行时动态改变的。实际上Python 内部提供的module 可以分成两类,一类是C 实现的builtin module 如thread,一类是用python 实现的标准库module。 p328:设置搜索路径、site-specific 的 module 搜索路径 sys.path 即 sys.__dict__['path'] 是一个 PyListObject...
