如何计算递归打印"你好世界"的次数？

Question

try:
def iwillcall():
def repeat_me():
print('hello world')
print(iwillcall())
print(repeat_me())   
iwillcall()
except RecursionError:
print('you reached the limit')

结果：

hello world
hello world
hello world
hello world
hello world
hello world
hello world
you reached the limit

我如何计算递归打印"你好世界"的次数？

Answer 1

以下解决方案使用全局变量

import sys

print(sys.getrecursionlimit())  # to get maximum recursion of the system you are using
i = 0
try:
def iwillcall():
global i
i = i+1
def repeat_me():
global i
i+=1
print('hello world')
print(iwillcall())
print(repeat_me())
iwillcall()
except RecursionError:
print('you reached the limit')
print(i+2)
