# 作业要求：下述所有代码画图以及分析代码执行流程
# 1、以定义阶段为准，先画出名称空间的嵌套关系图
# 2、然后找到调用函数的位置，写出函数调用时代码的执行过程，涉及到名字的查找时，参照1中画好
#    的嵌套图，标明查找顺序，一层一层直到找到位置


# ===================题目一===================
input=333
def func():
    input=444
func()
print(input)

# ===================题目二===================
def func():

x=111

func()


# ===================题目三===================
x=1
def func():
   print(x)
