def writer_oneRow_toFile(fileName, row):
	'''
	利用csv库实现数据一行行写入
	param: fileName, row
	'''
	with open(file,'a+',encoding='utf-8',newline='') as csvfile:
		spamwriter = csv.writer(csvfile, delimiter='|', quoting=csv.QUOTE_MINIMAL)
		spamwriter.writerow(row)

def deleteRepeatData(dataFrame):
	'''
	去除dataFrame中的重复数据
	param: dataFrame
	return: dataFrame
	'''
	return dataFrame.drop_duplicates()
