Posted 2022-08-11 wuyi_all_in

读取txt文件，将每行添加若干字符串，再写入到txt中

---

import numpy as np

#逐行读txt文件，并统一每行加字符串"_aligned."
with open("./1_test.txt") as txt:
    content = txt.readlines() #读全部行
    txt.close()
lines =np.array(content) #转换成array 类型
num_of_instances = lines.size #整个txt的行数
print("number of instances: ", num_of_instances)
list=[]
for i in  range(0,num_of_instances):
    line=lines[i]
    list.append("./mouth/"+line)

with open("./test.txt", w)as F:
    F.writelines(list)#写入到txt文件中
    print(list)
    F.close()
