如何在python中只获取文件？

import os

def get_files_only(directory):
    files = []
    for item in os.listdir(directory):
        if os.path.isfile(os.path.join(directory, item)):
            files.append(item)
    return files

# 调用示例
file_list = get_files_only('/path/to/directory')
print(file_list)

import glob

def get_files_only(directory):
    files = glob.glob(os.path.join(directory, '*'))
    files = [f for f in files if os.path.isfile(f)]
    return files

# 调用示例
file_list = get_files_only('/path/to/directory')
print(file_list)

import os

def get_files_only(directory):
    files = []
    for entry in os.scandir(directory):
        if entry.is_file():
            files.append(entry.name)
    return files

# 调用示例
file_list = get_files_only('/path/to/directory')
print(file_list)
