Question

因此，这段代码最初是一个函数，在帮助下，我将其分解为两个单独的函数，但是我仍在努力使其工作。任何指导将不胜感激

# -------------------------------------------
# Checks to see if listed folders exists and then deletes
# -------------------------------------------


def check_directory(path):
    # returns true if path is an existing directory
    return os.path.exists(path) and os.path.isdir(path)


dirs_to_delete = [
    'C:\Folder Here',
    'C:\Folder Here1',
    'C:\Folder Here2',
    'C:\Folder Here3'

 ]


def remove_directory(pathlist):
    for path in pathlist:
        if check_directory(path):
            shutil.rmtree(path)
            print(colored('Found ' + path + ' removing', 'green'))

我正在使用

调用此函数

remove_directory()     #Checks and Removes directories listed above

运行时出现以下错误

remove_directory()  #Checks and Removes directories listed above
TypeError: remove_directory() missing 1 required positional argument: 'pathlist'

Answer 1

您已将remove_directory定义为采用单个位置arg，pathlist，但是在全局范围内 not 却不采用变量pathlist的值：

s = 100

def print_val(s):
    print(s)

# I have not given it a positional arg, so s isn't defined
print_val()
# raises TypeError because the scope inside the function
# doesn't know what s is

# Now i give it that value
print_val(s)
# 100

因此，对于您的问题，您需要传递该arg

# This is how you call the function in your script
remove_directory(pathlist)

Answer 2

在您的帖子中，您似乎正在呼叫remove_directory，而没有根据需要传递列表，
将您的通话从remove_directory()更改为remove_directory(dirs_to_delete)

Answer 3

您需要将dirs_to_delete传递给函数：

remove_directory(dirs_to_delete)

Answer 4

调试：

TypeError: remove_directory() missing 1 required positional argument:

因为：

在这种情况下，功能remove_directory()需要一个参数，也许dirs_to_delete

因此：

def check_directory(path):
    # returns true if path is an existing directory
    return os.path.exists(path) and os.path.isdir(path)


dirs_to_delete = [
    'C:\Folder Here',
    'C:\Folder Here1',
    'C:\Folder Here2',
    'C:\Folder Here3'

 ]

def remove_directory(pathlist):
    for path in pathlist:
        if check_directory(path):
            shutil.rmtree(path)
            print(colored('Found ' + path + ' removing', 'green'))

remove_directory(dirs_to_delete)   # pass the list to the function here

Answer 5

remove_directory函数需要参数pathlist

由于您没有为pathlist添加默认值，因此调用remove_directory()失败。

尝试：

def remove_directory(pathlist=[]):
    for path in pathlist:
        if check_directory(path):
            shutil.rmtree(path)
            print(colored('Found ' + path + ' removing', 'green'))

或在调用函数时提供列表：

remove_directory([])

将路径列表传递给另一个函数
