Question

我认为以下代码的效率不足以搜索当前目录中的文件名。文件名将存储为字符串，那么 python 是否能够从非字符串的目录中搜索“文件名”字符串？

filename = input("What would you like to name the File? ")
import os
if f"{filename}.txt" in os.getcwd():
    print(True)

Answer 1

os.getcwd() 返回目录本身的名称，而不是文件列表（参见 https://www.tutorialspoint.com/python/os_getcwd.htm）

您想尝试以下操作：

import os
for file in os.listdir("/mydir"):
    if file == f"{filename}.txt:
        print("File Found")

Answer 2

此外，对于此代码段，您需要 try-except statement。否则，在错误的文件中，应用程序将崩溃。

Answer 3

import os 
# Getting current folder path
cmd = os.getcwd()
    # getting file name from user
    file_name = input('Enter file name to be search : ')
    #Looping through all folder and files in the current directory
    for file in os.listdir(cmd):
        # compare the file name user entered with file names from current 
        # directory file name
        if file == f"{file_name}.txt":
            print("File Found")

我的程序无法正确读取文件
