Last active August 15, 2021 09:05

python模拟C语言的静态局部变量

	def fibonacci():
	# 如果函数名太长, 为了编码的优雅方便, 建议起个别名.
	ctx = fibonacci
	# 在if not hasattr代码块里声明并初始化静态局部变量.
	# 如果需要用到多个静态局部变量, 只需要检查一个用不到的变量(如ctx.init)是否存在.
	# 完成初始化所需的静态局部变量之后, 记得初始化ctx.init. 如此这块代码才不会执行第二次.
	if not hasattr(ctx, "init"):
	ctx.a0, ctx.a1 = 1, 1
	# ctx.init的赋值是随意的. 我的习惯是赋一个有意义的值.
	ctx.init = "<<<Initialized>>>"
