利用pandas处理txt文件

import pandas as pd

# 假设你的TXT文件名为'my_file.txt'，并且使用逗号作为分隔符
df = pd.read_csv('./Emotion.txt')  # 如果是制表符分隔，使用'\t'，如果是其他字符分隔，替换为相应的字符


final_txt = []
for i,j in zip(df['label'],df['review']):
    
    if i == 1:
        i = '积极'
    elif i == 0:
        i = '消极'
    
    text = i + '\t' + j +'\n'
    final_txt.append(text)

with open('./waimai_data.txt','a',encoding='utf-8') as fp:
    for i in final_txt:
        fp.write(i)
