【Python】python读写txt和json文件

 python读写txt和json文件

1、往txt文件中写入内容

# write txt
import os

name =['a','b','c','d']
seq=['11111','22222','33333','44444']
        
output_dir = '/home/cqh/faceData'
emb_filename = os.path.join(output_dir, 'emb_txt.txt')

with open(emb_filename, "w") as f:
    for i in range(0, len(name)):
        f.write(name[i] + "\t" + seq[i] + "\n")
    f.close()

     运行结果如下：

2、从txt文件中读取内容

# read txt
emb_filename = '/home/cqh/faceData/emb_txt.txt'
fr = open(emb_filename)
for line in fr.readlines():  
    print(line)

      运行结果如下：

3、往json文件中写入内容

# write json
import os

name_emb = {'a':'1111','b':'2222','c':'3333','d':'4444'}
        
output_dir = '/home/cqh/faceData'   
emb_filename = os.path.join(output_dir, 'emb_josn.json')

jsObj = json.dumps(name_emb)  

with open(emb_filename, "w") as f:
    f.write(jsObj)
    f.close()

     运行结果如下：

4、从json文件中读取内容

# read json
emb_filename = '/home/cqh/faceData/emb_josn.json'
fr = open(emb_filename)

model=json.load(fr)
for i in model.keys():
    print('key: %s   value: %s' % (i, model[i]))

      运行结果如下;
