1.NAME=‘czd‘/
2.def zhangwuji():
    3.1 name = ‘张无忌‘
    3.2 print(name)
    3.3 def songqingshu():
       3.4.1  name=‘宋青书‘
       3.4.2  print(name)
       3.4.3 def zhaomin():
           3.4.5.1 name=‘赵敏‘
            3.4.5.1print(name)
        3.4.4 print(name)
        3.4.5 zhaomin()
    3.4 songqingshu()
    3.5 print(name)

def calc(n):
    print(n)
    if int(n/2) == 0:
        return n
    res = calc(int(n/2))
    return res


res=calc(10)
print(res)
执行结果如下：
