我正在使用python腳本來讀取文件，但它顯示爲IndentationError錯誤。這裏是我的代碼 import subprocess
f = subprocess.Popen(['tail','-F','filepath'],\
stdout=subprocess.PIPE,stderr=subprocess.PIPE)
while True:
line = f
x=8
print " hello"
print " whats ur name "
myName= raw_input()
print"nice to meet you " + myName
print" i had guess a number between 1 & 10 \ can u guess"
myVariable= raw_input()
if myVariable>
我想打印具有級別順序遍歷的非二叉樹。在下面的代碼中，每次添加一組新的子元素時，都會縮進，但當我再次返回樹時，我需要刪除縮進。以下是這棵樹打印： Root
Home
HomeChild1
HomeChild2
Documents (should be same level as Home)
DocumentChild1
Document
我如何糾正這個錯誤「意想不到的縮進」在python？ from fast_rcnn.config import cfg
from nms.cpu_nms import cpu_nms
def nms(dets, thresh, force_cpu=False):
"""Dispatch to either CPU or GPU NMS implementations."""
