python 2.7 shell 中的缩进错误

Question

嗨，当我在 python shell 中复制这个完整的片段时，出现缩进错误

---

import heapq    
dict = {4: 'four', 1 : 'one', 3: 'third', 2: 'two', 5:'five'}
h = []
for value in dict:
    heapq.heappush(h, value)

for i in range(len(h)):
    a = heapq.heappop(h)
    print a,'  ',dict[a]

---

但是如果我复制第一个块

import heapq    
dict = {4: 'four', 1 : 'one', 3: 'third', 2: 'two', 5:'five'}
h = []
for value in dict:
    heapq.heappush(h, value)

回车然后复制第二块

for i in range(len(h)):
    a = heapq.heappop(h)
    print a,'  ',dict[a]

点击回车，一切正常

请指导发生缩进问题的地方。

Answer 1

当您粘贴序列时：

for value in dict:
    heapq.heappush(h, value)

for i in range(len(h)):

自动缩进导致：

for value in dict:
    heapq.heappush(h, value)

    for i in range(len(h)):

因此你的问题。
