Question

我m doing a very simple piece of code, and it keeps generating a Syntax error, multiple statements found while compiling a single statement. I can看到我的代码出了什么问题！ :(，请查看链接，因为我在这里输入的代码可能是正确的，但我看不出它与IDLE链接之间的区别。

我试图将字符串'10'转换为整数，因此if语句可以正常工作。

这是屏幕截图。 http://www.screencast.com/t/0zItqcn5P6d

age = '10'
converted_age = int(age)
if converted_age == 10:
    print("whats the best way to speak to a monster?")
    print("from as far away as possible!")

Answer 1

你错过了：在你的if语句之后。

好吧，我刚刚执行了

age = '10'
converted_age = int(age)
if converted_age == 10:
    print("whats the best way to speak to a monster?")
    print("from as far away as possible!")

使用python2.7和3.0，对我来说似乎没问题。我不能重现它，因为你刚才说你有相同的语法。

那条橙色线是什么？复制并粘贴完全相同的代码。尝试一下。

Answer 2

age = '10'
converted_age = int(age)
if converted_age == 10:
                      ^ Colon needed here.
    print("whats the best way to speak to a monster?")
    print("from as far away as possible!")

控制台会话：

>>> age = '10'
converted_age = int(age)
if converted_age == 10:
    print("whats the best way to speak to a monster?")
    print("from as far away as possible!")
whats the best way to speak to a monster?
from as far away as possible!

在屏幕截图中，您使用ConvertedAge存储变量，但与converted_age进行比较，这会导致错误，因为covnerted_age未定义。

Answer 3

您的屏幕播放显示错误，因为converted_age未定义。

您有convertedAge = int(age)并且您正在尝试比较未定义的converted_age。

python将字符串转换为带有int（）的整数，语法错误，找到多个语句
