SyntaxError：呼叫'打印'中缺少圆括号

-5

我一直在尝试刮取一些Twitter的数据，但是当我运行此代码时，出现错误SyntaxError: Missing parentheses in call to 'print'。SyntaxError：呼叫'打印'中缺少圆括号

有人可以帮我一个这个吗？

感谢您的时间:)

你试图在Python 3运行Python 2代码之间留出的空间。 –

我知道这会让你震惊，但是......你打电话给'print'......它缺少括号。（'print r' - >'print（r）'） –

你有没有做过任何研究？它在[问]指南中，有几个关于堆栈溢出的问题。 –

在蟒蛇2，打印已经声明，不是一个函数。这意味着你可以在没有括号的情况下使用它。在python 3中，这已经改变了。这是一个函数，你需要使用print（foo）而不是print foo。

值得注意的是，我一直使用括号。这些无意义的变化从未打扰过我。再次，我仍然用C表示返回的值。有时候，那些没有被修改以跟上Joneses运行良好的事情，即使在Joneses改变他们的模式以跟上Smiths之后。 –

看起来好像你正在使用python 3.x，但是你在这里运行的代码是python 2.x代码。有两种方法来解决这个问题：

下载python 2.X上Python's website，并用它来运行脚本
在你打印电话在年底通过在年底通过print(r)更换print r添加括号（并继续使用蟒蛇3）

但今天，越来越多的广大Python程序员都使用python 3，官方python wiki规定如下：

Python 2.x is legacy, Python 3.x is the present and future of the language

如果我是你，我会选择第二个选项去继续使用Python 3

看起来你想在Python 3，其中print是function运行Python 2代码和所需的括号：

print(foo)

你只需要pranethesis添加到您的打印statmetnt将其转换为一个功能，如错误说：

print expression -> print(expression)

在Python 2，打印是一个声明，但在Python 3，打印是福nction。所以，你可以只交替运行您的代码与Python 2 print(expression)是与Python 2

而且向后兼容的，你为什么要善用您的所有意见？它很烦人。您的代码也以几种方式违反PEP 8。得到像PyCharm这样的编辑器（它是免费的），可以自动检测这样的错误。

你没有离开#和您的评论
之间的空间你没有=和其他标记
