生成器是迭代器,但你只能遍历它一次(iterate over them once) 因为生成器并没有将所有值放入内存中,而是实时地生成这些值 >>> mygenerator = (x*x for x in range(3)) >>> for i in mygenerator: ... print(i) 0 1 4 这和使用列表解析地唯一区别在于使用()替代了原来的[] 注意,你不能执行for ...

Return sends a specified value back to its caller whereas Yield can produce a sequence of values. We should use yield when we want to iterate over a sequence, but don't want to store the entire sequence in memory. import sys # for example when reading a large file, we only care about...

Excluding files Exclusions are based on globs, and can be either: Single-path patterns, like .mypy_cache (to exclude any directory named .mypy_cache in the tree), foo.py (to exclude any file named foo.py), or foo_*.py (to exclude any file matching foo_*.py ). Relative patterns, ...
