Python File Search: Find Files by Name

In Python, the os module can be used to search for files with a specific name. Here is a common method:

import os

def find_files(directory, filename):
    results = []
    for root, dirs, files in os.walk(directory):
        if filename in files:
            results.append(os.path.join(root, filename))
    return results

# 指定要搜索的目录和文件名
directory = "C:/Users/username/Documents"
filename = "example.txt"

# 查找指定名称的文件
found_files = find_files(directory, filename)

# 输出结果
if found_files:
    print("找到以下文件：")
    for file in found_files:
        print(file)
else:
    print("未找到指定文件")

The find_files function in the code above takes a directory and a file name as parameters, and uses the os.walk function to traverse all files in the directory and its subdirectories. If a file with the specified name is found, its path is added to the result list. Finally, the corresponding information is output based on the result list.
