我在运行以下代码时遇到错误:
class Person:
def _init_(self, name):
self.name = name
def hello(self):
print 'Initialising the object with its name ', self.name
p = Person('Constructor')
p.hello()
输出为:
Traceback (most recent call last):
File "./class_init.py", line 11, in &
我的程序说有一个错误,它不需要任何参数。有谁能发现这个错误吗?在30号线和12号线。谢谢 class City():
#define the structure and content of the Student Record
def _init_(self, name, country, population, language):
self.name = name #name will be a string
self.country = country #country will be a string
self.population = popul
我有一个正在处理的python文件:
class Range:
""" An object that has a non-negative start position and a non-negative length"""
def __init__(self, start, end):
"""
Function: generates a new Range
Returns : a new range
我正在创建一个可停止的线程类:
import threading
class StoppableThread(threading.Thread):
"""Thread class with a stop() method. The thread itself has to check
regularly for the stopped() condition."""
def __init__(self):
super(StoppableThread, self).__init__()
s
对于Java,我写了一个类来读取文件,并计算文件中的单词、句子和字母的数量。下面是我的构造函数
//default constructor
public FileScanner(File f){
f = null;
}
//constructor (file)
public FileScanner(int word, int letter, int sentence, int averageWord){
numWord = word;
numLetter = letter;
numSentence = sentence;
average = avera
在Python2中,我使用这种简单的方法来运行Thread,并通过args传递参数: import threading
class FuncThread(threading.Thread):
'''
it worked fine in Python2
'''
def __init__(self, target, *args):
self._target = target
self._args = args
print( self._args )
(function() {
var Emp = function(_name, _salary) {
var name = _name;
var salary = _salary
return {
name: name,
salary: salary
};
}
Emp.prototype.work = function(){
console.log('this is work',this);
}
var Car = function(_name, _model) {
this
我试图使用StoppableThread类表示为
import threading
# Technique for creating a thread that can be stopped safely

class StoppableThread(threading.Thread):
"""Thread class with a stop() method. The thread itself has to check

print("Enter number of test cases and length of each string")
t,s=map(input,range(2))
print(t,s)
提示输入测试用例数和每个字符串的长度03 13,为什么3前面有0和1?
下面这行显示了输出
t,s=map(lambda x :input ,range(2))
OUTPUT-<built-in function input> <built-in function input>
WHY IS THAT?
而这一行:
t,s=map(int(input()),ra

上面是带有属性的uiautomator对象查看器屏幕截图。我使用的是通过pip install uiautomator安装的。我试图通过UI自动对象访问三个虚线设置按钮。我试过使用上列出的文档

使用非注入字段在无状态EJB中使用空构造函数是否符合Java,如本例所示?
@WebService
@Stateless
@SOAPBinding(...)

private final Set<PrivacyO> allowed;
public ParameterWebservice() {
allowed= new HashSet<>();

好吧,看起来我没有提供足够的信息。因此,最终目标是运行基于某些子网的goal扫描。因此,我创建了一个包含子网的文本文件,然后运行runs扫描,并提供所有IP可达的输出。 Here is the pingsweep code 我得到了这个错误: Traceback (most recent call last):
File "pingsweep1.py", line 118, in <module>
sub = subnet(line)
TypeError: this constructor takes no arguments 任何帮助都将不胜感激。
我写了一些代码:
mon=10
a=1
print("You have",mon,"pounds")
bet=input("How much do you want to bet?")
if bet % 1==0:
bet=int(bet)
else:
print("Give me a whole number please")
但当我回答时我得到:
Traceback (most recent call last):
if bet % 1==0:
TypeError: not all arguments

我的名字是Piyush,我刚刚开始学习用python编写代码。现在我正在做一个项目。如果任何人能够帮助在函数中添加自定义参数,我将非常感激。我在下面提到我的代码和我所面临的问题:

使用python2.7.3,以下内容不会引发TypeError。

u''
但是,传递errors参数会引发TypeError: decoding Unicode is not supported
