在def(pentagon):块中我命名了一个变量" first".但是,这会导致"无效语法"错误.怎么了？我已经尝试过命名其他东西,从单个字母到低级/大写字母组合,如"preArea".

print('This program will tell you the area some shapes')

在上下文中,如果我用"悲伤","可怕"甚至"asdfasdfasdf"回答其最初的问题,我仍会得到积极的回应.
应该发生的是如果我输入一个否定/不明确的关键字,应该调用negResponses()/ ambiguousResponses()function.事实并非如此.我做错了什么,我该如何解决？代码如下:
import random
import time
def opening():
print('Hello!')
def responseType():
responseType = str(input('How are you ?'))
if responseType == 'good' or 'great' or 'fantastic' or 'decent' or 'fine' or 'ok' or 'okay': posResponses()
elif responseType == 'bad' or 'terrible' or 'sad' or 'grumpy' or 'angry' or 'irritated' or 'tired': negResponses()
else: ambiguousResponses()
def posResponses():
number = random.randint(1, 4)
if number == 1:
print('That\'s great! So what\'s up?')
input()
ambiguousResponses()
if number == …如果你运行我在下面包含的代码(python 2.7),你会发现结果图像是黑暗和模糊的,几乎看起来有条纹在它上面运行.我意识到使用分散函数绘制这样的东西可能是滥用功能.
我仔细阅读了文档并迷失在其中,只是希望有人能告诉我如何让我的Julia套装看起来像你在书本和网上看到的漂亮的彩色印版一样漂亮.

我一开始认为做以下事情会给我想要的东西:
[1, 3, 4] ++ [4, 5, 6]
但正如你所知,只给[1,2,3,4,5,6].
我需要做什么来接受[1,2,3]和[4,5,6]并且[[1,2,3],[4,5,6]]？
我试图制作一个简短的程序来解决着名的德雷克方程.我让它接受整数输入,十进制输入和小数输入.但是,当程序试图将它们相乘时,我收到此错误(在我输入所有必要值之后,错误发生):

那么,我该如何改变立场？
我从c ++入门书中得到了这段代码,这本书旨在解释删除操作符.但是,我不明白的是程序如何调用这两个函数以及它们如何交互.
// delete.cpp -- using the delete operator
#include <iostream>
#include <cstring> // or string.h
using namespace std;
char * getname(void); // function prototype
int main()
{
char * name; // create pointer but no storage
name = getname(); // assign address of string to name
cout << name << " at " << (int *) name << "\n";
delete [] name; // memory freed
name = getname(); // reuse freed memory
cout << name << " at " …我知道您可以在Python GUI中打开文件,浏览器和URL.但是,我不知道如何将其应用于程序.例如,以下都不起作用.(以下是我不断增长的聊天机器人程序的片段):

handle.open('http://youtube.com')

和
def file():
file = str(input('ENTER THE FILE\'S NAME AND EXTENSION:'))
action = open(file, 'r')
actionTwo = action.read()
print (actionTwo)
就上述顺序而言,这些错误发生在个别运行中:
