相关疑难解决方法(0)

我正在使用格式化Python代码pylint并获取一些不需要的警告消息,如下所示.

C:204, 0: Invalid function name "sendPasswordViaEmail" (invalid-name)
C:207, 4: Invalid variable name "to" (invalid-name)
W:213, 4: Statement seems to have no effect (pointless-statement)

我正在解释与以下消息相关的代码.

if request.method == 'POST':
        name = request.POST.get('uname')
        email = request.POST.get('uemail')
        range_start = 10 ** (4 - 1)
        range_end = (10 ** 4) - 1
        password = randint(range_start, range_end)
        passw = User(
            uname=name,
            password=password,
            raw_password=password,
        )
        passw.save()
        sendPasswordViaEmail(str(password), email)
    return render(request, 'bookingservice/login.html')


def sendPasswordViaEmail(password, email):
    """ Send email to user"""

    to = email
    gmail_user …

为什么 PyLint 要求变量具有 UPPER_CASE 命名，就好像它是常量一样？

"""Stack reproducible example."""

some_list = ['foo', 'bar']
for i in some_list:
    counter = 3
    while counter != 0:
        print("Value of 'counter': " + str(counter))
        counter -= 1

这给出了以下 linting 错误：

# C0103: Constant name "counter" doesn't conform to UPPER_CASE naming style (invalid-name)

然而，与阿伏加德罗的常数、圆周率或真空中的声速不同， counter变化的值肯定必须使其成为“变量”？

我已阅读有关C0103 的页面，但我显然不明白某些内容。

for 循环是否被视为一次性函数，从而改变了约定，例如在这个问题中？
