在目录中列出文件，并存储在数组中。可以在循环外部访问该数组

import os

def list_files_in_directory(directory):
    file_array = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_array.append(os.path.join(root, file))
    return file_array

# 调用函数，并指定目录路径
directory_path = "/path/to/directory"
files = list_files_in_directory(directory_path)

# 在循环外部访问存储文件的数组
for file in files:
    print(file)
