几行代码后如何更改变量的值-Python

Question

经过一行代码后，如何更改变量的值？

例如

hungerlevel= "very high"
print (hungerlevel)
for i in range (0,3):
   print ("I ate an apple")

，然后在此循环之后，将变量的值更改为

hungerlevel= "low"
print(hungerlevel)

因此使程序类似于

hungerlevel= "very high"
print (hungerlevel)
for i in range (0,3):
   print ("I ate an apple")
hungerlevel= "low"
print(hungerlevel)

所以最后显示的结果是

Very high 
I ate an apple
I ate an apple
I ate an apple
low
