Python raising FileNotFoundError for file name returned by os.listdir（3个答案）
7天前关闭
我试图将所有.txt文件的内容合并到一个目录中，该目录比下面存储.py文件的目录高一级。

import os

def main():
    # Get list of files stored in a dir above this .py's dir
    folder = os.listdir("../notes")

    # Merge the files
    merge_files(folder)

def merge_files(folder):
    # Create a list to store the names of the files
    files_names = []

    # Open output file in append mode
    with open("merged_notes.txt", "a") as outfile:
        # Iterate through the list of files
        for file in folder:
            # Add name of file to list
            files_names.append(file)
            print(files_names)

            # Open input file in read mode
            with open(file, "r") as infile:

                # Read data from input file
                data = infile.read()
                
                # Write data to output file (file name, data, new line)
                outfile.write(file)
                outfile.write(data)
                outfile.write("\n")

    # Return merged file
    return "merged_notes.txt"

if __name__ == "__main__":
    main()

我一直得到这个错误：
文件未找到错误：[错误2]没有这样的文件或目录：'文件日期Mar 30 2023，4 30 48 PM.txt'
然而，文件名 is 保存在列表files_names中，这意味着for循环 * 确实 * 在“notes”目录中找到了文件。我不明白为什么with open(file, 'r')没有。
