python - Alternative to dict comprehension prior to Python 2.7

Question

How can I make the following functionality compatible with versions of Python earlier than Python 2.7?

gwfuncs = [reboot, flush_macs, flush_cache, new_gw, revert_gw, send_log]      
gw_func_dict = {chr(2**i): func for i, func in enumerate(gwfuncs[:8])}

Answer 1

利用：

gw_func_dict = dict((chr(2**i), func) for i, func in enumerate(gwfuncs[:8]))

这就是dict()生成器表达式产生(key, value)对的函数。

或者，通俗地说，是对以下形式的 dict 理解：

{key_expr: value_expr for targets in iterable <additional loops or if expressions>}

始终可以通过以下方式与 Python < 2.7 兼容：

dict((key_expr, value_expr) for targets in iterable <additional loops or if expressions>)
