Question

我在python中创建了一个类，当我尝试将其调用到另一个python文件中（导入后）时，它不能将其识别为类，而是一个对象，然后它告诉我该类不可调用< / p>

这是我的课：

class Cell:
    def __init__(self,value=9,isVissible=False):
        self.value=value
        self.isVisible=isVissible
    def setValue(self,value):
        self.value=value
    def setVisible(self):
        self.visible=True

这是我试图称呼它的地方：

import Cell,random
class Board:
    def __init__(self):
        self.board = []
        for i in range(12):
            a = []
            for j in range(12):
                x = Cell()   <=== right here it's an error
.
.
.(the rest of my program)

最后是错误：

x=Cell()
TypeError: 'module' object is not callable

有人可以帮我解决这个问题，即使我的老师也不明白我的错误

Answer 1

void Main() { List<Person> personList = new List<Person>() { new Person{ Name = "Shekhar", Age = 31}, new Person{ Name = "Sandip", Age = 32}, new Person{ Name = "Pramod", Age = 32}, new Person{ Name = "Kunal", Age = 33} }; var personNameList = personList.Select(p => p.Name).ToList(); var personNameHashset = new HashSet<string>(personNameList); var nameList = new List<string>() { "Kunal", "Pramod", "Mrinal" }; var finalExpression = personNameHashset.EqualExpression<string>("Name"); var finalFunc = finalExpression.Compile(); var result = nameList.Where(finalFunc); result.Dump(); } public class Person { public string Name { get; set; } public int Age { get; set; } } public static class ExpressionTreesExtension { public static Expression<Func<T, bool>> EqualExpression<T>(this HashSet<string> nameHashSet, string columnName) { var expressionList = new List<Expression>(); ParameterExpression parameterType = Expression.Parameter(typeof(T), "obj"); // Exception Here - How to create MemberExpression for primitive type list List<string> MemberExpression memberExpressionColumn = Expression.Property(parameterType,columnName); var containsMethodInfo = typeof(StringListExtensions).GetMethod("Contains", new[] { typeof(string), typeof(HashSet<string>) }); ConstantExpression constant = Expression.Constant(nameHashSet, typeof(HashSet<string>)); var resultExpression = Expression.Call(null, containsMethodInfo, memberExpressionColumn, constant); return Expression.Lambda<Func<T, bool>>(resultExpression, parameterType); } } public static class StringListExtensions { /// <summary> /// String Extension - Contains (Substring) /// </summary> /// <param name="source"></param> /// <param name="subString"></param> /// <returns></returns> public static bool Contains(this string name, HashSet<string> nameHashSet) { return nameHashSet.Contains(name); } }已用于您导入的模块和您的类。根据错误，python已将其映射到模块名称。因此，在编写Cell时，它会尝试将模块名称用作函数，而不是调用类构造函数。

如果类Cell()在Cell模块内部，请改用Cell，或将导入更改为Cell.Cell()。否则，请重命名模块或类。

您的导入语句是错误的，您正在导入一个名为Cell的模块，而不是Cell类。您应该使用小写字母作为文件名并按如下所示导入：

from cell import Cell


test = Cell()

python-为什么我的程序告诉我它不可调用
