获取文件上次修改日期和文件名pyspark的脚本

Question

我有一个挂载点位置，它指向一个blob存储，其中有多个文件。我们需要找到文件的最后修改日期以及文件名。我正在使用下面的脚本 文件列表如下：

/mnt/schema_id=na/184000-9.jsonl
/mnt/schema_id=na/185000-0.jsonl
/mnt/schema_id=na/185000-22.jsonl
/mnt/schema_id=na/185000-25.jsonl

import os
import time
# Path to the file/directory
path = "/mnt/schema_id=na"
         
ti_c = os.path.getctime(path)
ti_m = os.path.getmtime(path)
        
c_ti = time.ctime(ti_c)
m_ti = time.ctime(ti_m)
          
print(f"The file located at the path {path} was created at {c_ti} and was last modified at {m_ti}")

Answer 1

这里有一种方法可以实现：

import os
import time
# Path to the file/directory
path = "/dbfs/mnt/schema_id=na"

for file_item in os.listdir(path):
    file_path = os.path.join(path, file_item)
    ti_c = os.path.getctime(file_path)
    ti_m = os.path.getmtime(file_path)
        
    c_ti = time.ctime(ti_c)
    m_ti = time.ctime(ti_m)
          
    print(f"The file {file_item} located at the path {path} was created at {c_ti} and was last modified at {m_ti}")
