示例代码：

public class MyClass {

    public static double globallyVisibleDbl = 42.69;
    public static final int globallyVisibleInt = 42;
    //blah blah rest of code

}

并且在一个类中都有双精度类型的变量和常量。

但是，当我尝试将这两个外部类放到类之前（例如，在类之前和导入语句之后）时，就像在C或C ++中由于#define token [value]指令允许的那样，我得到了错误：

import com.something.*;

public static double globallyVisibleDbl = 42.69;
public static final int globallyVisibleInt = 42;

public class MyClass {
   //some code
}

为什么会这样呢？

我有这个代码:

def time24hr(tstr):

    if ('a' and ':') in tstr:
        if tstr[:2] == '12':
            tstr = tstr.replace('12', '00').replace(':','').replace('am','hr')
            return tstr

        elif len(tstr[:tstr.find(':')]) < 2:
        # If length of string's 'tstr' slice (that ends before string ':') is less than 2
            tstr = tstr.replace(tstr[:tstr.find(':')],'0' + tstr[:tstr.find(':')]).replace(':', '').replace('am','hr')
            # Replace one-character string with combination of '0' and this one-character string. Then remove colon, by replacing it with lack of characters and replace 'am' string with 'hr'.
            return tstr

        else:
            tstr = tstr.replace(':', '').replace('am', …
