本文介绍了一种Python脚本实现的方法，用于从文件中加载字典并进行文本处理任务，如将特定词汇转换为标记格式。脚本还演示了如何将修改后的数据保存到新的输出文件中。

# encoding: utf-8
def load_dict_from_file(filepath):
	_dict = {}
	try:
		with open(filepath, 'r') as dict_file:
			for line in dict_file:
				(key, value) = line.strip().split('\t')
				_dict[key] = value
	except IOError as ioerr:
		print "文件 %s 不存在" % (filepath)

	return _dict

def save_dict_to_file(_dict, filepath):
	try:
		with open(filepath, 'w') as dict_file:
			for (key,value) in _dict.items():
				dict_file.write('%s\t%s\n' % (key, value))
	except IOError as ioerr:
		print "文件 %s 无法创建" % (filepath)
 
if __name__ == '__main__' :
	_dict = load_dict_from_file ('dict.txt')
	#print _dict
	#save_dict_to_file(_dict, 'dict_copy.txt')
	f2=open("output.txt",'w')
	with open ('input.txt','r') as f1:
		for line in f1:
			str1=line.split()
			for i in range(1,len(str1)):
				if str1[i].isupper():
					str1[i]='/ '+str(_dict.get(str1[i]))+' /'
					print str1[i]
			f2.write(' '.join(str1)+'\n')
	# f2=open("output.txt",'w')
	# with open ('all_py.txt','r') as f1:
		# for line in f1:
			# str1=line.split()
			# for i in range(1,len(str1)):
				# str1[i]=str(_dict.get(str1[i]))
				#print str1[i]
			# f2.write(' '.join(str1)+'\n')
