SyntaxError：呼叫'打印'中缺少圓括號

-5

我一直在嘗試刮取一些Twitter的數據，但是當我運行此代碼時，出現錯誤SyntaxError: Missing parentheses in call to 'print'。SyntaxError：呼叫'打印'中缺少圓括號

有人可以幫我一個這個嗎？

感謝您的時間:)

你試圖在Python 3運行Python 2代碼之間留出的空間。 –

我知道這會讓你震驚，但是......你打電話給'print'......它缺少括號。（'print r' - >'print（r）'） –

你有沒有做過任何研究？它在[問]指南中，有幾個關於堆棧溢出的問題。 –

在蟒蛇2，打印已經聲明，不是一個函數。這意味着你可以在沒有括號的情況下使用它。在python 3中，這已經改變了。這是一個函數，你需要使用print（foo）而不是print foo。

值得注意的是，我一直使用括號。這些無意義的變化從未打擾過我。再次，我仍然用C表示返回的值。有時候，那些沒有被修改以跟上Joneses運行良好的事情，即使在Joneses改變他們的模式以跟上Smiths之後。 –

看起來好像你正在使用python 3.x，但是你在這裏運行的代碼是python 2.x代碼。有兩種方法來解決這個問題：

下載python 2.X上Python's website，並用它來運行腳本
在你打印電話在年底通過在年底通過print(r)更換print r添加括號（並繼續使用蟒蛇3）

但今天，越來越多的廣大Python程序員都使用python 3，官方python wiki規定如下：

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

如果我是你，我會選擇第二個選項去繼續使用Python 3

看起來你想在Python 3，其中print是function運行Python 2代碼和所需的括號：

print(foo)

你只需要pranethesis添加到您的打印statmetnt將其轉換爲一個功能，如錯誤說：

print expression -> print(expression)

在Python 2，打印是一個聲明，但在Python 3，打印是福nction。所以，你可以只交替運行您的代碼與Python 2 print(expression)是與Python 2

而且向後兼容的，你爲什麼要善用您的所有意見？它很煩人。您的代碼也以幾種方式違反PEP 8。得到像PyCharm這樣的編輯器（它是免費的），可以自動檢測這樣的錯誤。

你沒有離開#和您的評論
之間的空間你沒有=和其他標記
