Question

我想在程序中执行以下操作：

a）要求用户键入文件夹的名称
b）在我的目录中创建文件夹
c）将文件写入此创建的文件夹

我已经在目录中创建了该文件夹，但是我没有设法将文本写入文件并将其保存在该新文件夹中。我的策略是打开以插入目录的完整路径+存储文件夹名称的变量来打开文件，但没有用。有人可以帮我吗？

 final_text=' '.join(l)
    final_text=final_text.replace(' ,',',')
    #print('\n\n', final_text)

    def createFolder(directory):
        try:
            if not os.path.exists(directory):
                os.makedirs(directory)
        except OSError:
            print('Error: Creating directory. '+ directory)

    user2=input('\nWrite text to a file? Type "Y" for yes or "N" for no:')

    if user2 =='Y':
        text_name=input("name your folder. E.g. './texts/': ")
        createFolder(text_name)
        out_file=open('/Users/nataliaresende/Dropbox/PYTHON/'+text_name,"w")
        out_file.write(final_text)
        out_file.close()
        print('\n\nText named',text_name, 'was written to a file. Check your directory')

    else:
        print('ok')

Answer 1

Python的pathlib库（可从Python 3.4+开始使用）使这种事情成为真正的乐趣：

import pathlib


new_dir_name = input('Directory name: ')
new_dir = pathlib.Path('/Users/nataliaresende/Dropbox/PYTHON/', new_dir_name)
new_dir.mkdir(parents=True, exist_ok=True)
# You have to make a file inside the new directory
new_file = new_dir / 'myfile.txt'
new_file.write_text('Hello file')

您可以先创建文件夹，然后在该文件夹中创建文件：

import os

user_input = input('\nWrite text to a file? Type "Y" for yes or "N" for no:')
if user_input == 'Y':
    folder_name = input('name your folder. E.g. "texts": ')
    folder = os.path.join('/Users/nataliaresende/Dropbox/PYTHON/', folder_name)
    file_name = '{}.txt'.format(folder_name)
    file = os.path.join(folder, file_name)
    os.makedirs(folder)
    with open(file, 'w') as f:
        f.write('Some text')
    print('\n\nText named "{}" was written to a file. Check your directory: {}'.format(file_name, folder))
else:
    print('OK')

在目录中创建一个文件夹并将文件保存在新文件夹中
