How can i fix TypeError: unsupported operand type(s) for +: 'WindowsPath' and 'str'

Question

你好，我正在使用 python 并想将一些内容写入文本文件，但它不起作用... 我的代码错误部分：

working_directory = Path(__file__).absolute().parent
profilename1 = Banana
getProductFile = (working_directory + profilename1+".txt")
with open(getProductFile, 'a') as f:
    print('\n'.join(list), file=f)
    print('\n'.join(list1), file=f)

当我 运行 时，我得到这个错误：

Exception in thread Thread-2:
Traceback (most recent call last):
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.8_3.8.2800.0_x64__qbz5n2kfra8p0\lib\threading.py", line 932, in _bootstrap_inner

    getProduct()
  File "C:\Users\yvesb\OneDrive\Desktop\Script\SATURN.py", line 265, in getProduct
    getProductFile = (working_directory + profilename1+".txt")
TypeError: unsupported operand type(s) for +: 'WindowsPath' and 'str'

我该如何解决？

Answer 1

您必须将路径与 / 而非 +:

组合

working_directory = Path(__file__).absolute().parent
profilename1 = Banana
product_file = working_directory / (profilename1 + ".txt")
with product_file.open('a') as output:
    print('\n'.join(list), file=output)
    print('\n'.join(list1), file=output)

Answer 2

使用Path.joinpath或os.path.join代替字符串连接

getProductFile = Path.joinpath(working_directory, profilename1 + ".txt")
getProductFile = os.path.join(working_directory, profilename1 + ".txt")

Answer 3

有两种方法可以将新路径部分连接到 pathlib.Path、方法或重写的 /

getProductFile = working_directory.joinpath(profilename1 + ".txt")
getProductFile = working_directory / (profilename1 + ".txt")

然后你在with块中重新定义f，它应该更像

with open(getProductFile, 'a') as f:
    print('\n'.join(list), file=f)
    print('\n'.join(list1), file=f)
