循环,获取键字符串的首字母 0
,并将其添加到整个密钥:
foreach($array as $k => $v) {
$result[strtoupper($k[0])][$k] = $v;
}
我使用 data_files
data_files = [('', ['negar/data/untouchable.dat'])],
此调用中的第二个参数表达式
scanf("%s", *(*(p+x)+y));
^^^^^^^^^^^
具有 char
的类型,但由于使用了使用的转换规范器 s
该函数期望类型 char *
的参数。结果,该程序的行为不确定。
要输入字符串,您只需要一个即可进行循环。
如果要通过字符输入字符而不是输入字符串,则循环可以使用指针来查看以下方式,
for ( char ( *row )[20] = p; row != p + 3; ++row )
{
for ( char *item = *row; item != *row + sizeof( *row ); ++item )
{
scanf( " %c", item );
}
}
for ( char ( *row )[20] = p; row != p + 3; ++row )
{
for ( char *item = *row; item != *row + sizeof( *row ); ++item )
{
printf( "%c", *item );
}
putchar( '\n' );
}
请注意 scanf
的格式字符串中的领先空间,
scanf( " %c", item );
^^^^
它允许跳过白色空间字符为例如新行字符'\ n'
。
如果要在数组中输入字符串,则循环看起来像
for ( char ( *row )[20] = p; row != p + 3; ++row )
{
scanf( "%19s", *row );
}
for ( char ( *row )[20] = p; row != p + 3; ++row )
{
printf( "%s\n", *row );
}
draggingEntered
和 cormaldragoperation
是协议的方法 nsdraggingDestination
。如果类不采用协议,Swift不会调用协议方法。 AppDelegate
必须采用 nsdraggingDestination
。
extension AppDelegate: NSWindowDelegate {
}
extension AppDelegate: NSDraggingDestination {
func draggingEntered(_ sender: NSDraggingInfo) -> NSDragOperation{
NSApplication.shared.activate(ignoringOtherApps: true )
return .copy
}
func performDragOperation(_ sender: NSDraggingInfo) -> Bool{
NSApplication.shared.activate(ignoringOtherApps: true )
return true
}
}
如果性能或大数据框使用 通过重复行的几天差异,counter to_timedelta
和最后对删除重复的分类:
df['d_of_arr'] = pd.to_datetime(df['d_of_arr'])
df['d_of_sty'] = pd.to_datetime(df['d_of_sty'])
df = df.loc[df.index.repeat(df['d_of_sty'].sub(df['d_of_arr']).dt.days.add(1))]
df['dates'] = df['d_of_arr'].add(pd.to_timedelta(df.groupby(level=0).cumcount(), unit='d'))
df1 = df[['Id','dates']].sort_values(['Id','dates']).drop_duplicates(ignore_index=True)
或者如果小型dataframe或ynes thateframe或ynes cormapor note cormes 对于新行:
df['dates'] = [pd.date_range(s, e) for s, e in zip(df['d_of_arr'], df['d_of_sty'])]
df1 = (df.explode('dates')[['Id','dates']]
.sort_values(['Id','dates'])
.drop_duplicates(ignore_index=True))
print (df1)

在使用gameObject.find时检查是否找到东西。为此,您可能可以使用公共变量并将其设置为Inspector中的对象。

Tolocaleformat
已弃用了一段时间,并从版本58开始就从Firefox中删除。请参见
tolocaleformat
我认为您只能使用非标准 date方法 tolocaleformat(formatstring)
格式:
var today = new Date();
today.toLocaleFormat('%d-%b-%Y'); // 30-Dec-2011
参考:
unicodedata.normalize
在列表上不起作用,因此列举列表并转换每个单词:
import unicodedata as ud
words = '''âcre âge âgé arriéré arrière bronzé collé congrès coté côte côté crêpe
crêpé cure curé dès différent diffèrent entré mémé même pâte pâté péché
pêche pécher pêcher pécheur pêcheur prête prêté relâche relâché retraité
sublimé vôtre'''.split()
for index, word in enumerate(words):
words[index] = ''.join(c for c in ud.normalize('NFD', word) if ud.category(c) != 'Mn')
print(words)
输出:
['acre', 'age', 'age', 'arriere', 'arriere', 'bronze', 'colle', 'congres', 'cote', 'cote', 'cote', 'crepe', 'crepe', 'cure', 'cure', 'des', 'different', 'different', 'entre', 'meme', 'meme', 'pate', 'pate', 'peche', 'peche', 'pecher', 'pecher', 'pecheur', 'pecheur', 'prete', 'prete', 'relache', 'relache', 'retraite', 'sublime', 'votre']
它对我来说很好(Ubuntu:20.04.4 LTS,VSCODE:1.68.0),应该以相同的方式用于Linux或Windows。 https://en.wikipedia.org/wikipedia.org/wiki/wiki/wiki/table_of_keykeyboard_shortcuts 。

在git中,文件没有具有历史记录。 Consits 是历史记录,您可以通过选择一个或多个感兴趣的提交来过滤历史记录。
一种方法是说告诉我有关文件x更改的提交。也就是说,git一次查看每个提交,一次,git一直向后倾斜,git始终以:
commit 61892BB913DB3E9815914E062439364A333666A78
:在此提交中文件x更改吗? (在两个副本中提取parent and Commit并比较文件x)提交A9015FBB8599F2F67DA593F89634A728F04EB132
:File x Change x Change在此提交中是否更改? (提取父和提交和比较文件x是两份副本)每当git遇到一个提交一个comm实例 -
git log
will display 该提交。那不是“文件历史记录”,而是“过滤的提交历史记录”,就像 /a>不是Mona Lisa,它是Mona Lisa的图像。没有区别的区别?好吧,也许不是,因为...
git日志 - follow
使用
git log -follow -x
,您告诉git log
它应该过滤历史记录,这是git log -x
的方式,但是这次 应该检查是否包含对文件文件的更改文件的可能性是重命名 。如果文件被重命名,则git log - follow
像之前一样打印提交,但是它停止寻找x 并开始寻找
o
而不是其中
o
是文件的 old 名称。换句话说,序列中的每个测试现在都是 确实在此提交中更改o更改而不是 dik dik di file x更改此提交。这里有局限性。最大的两个是:
这仅起作用“向后”。您必须知道文件的 new 名称,然后运行
git log -follow -new/path/to/file
实例。这仅适用于一个文件。
一个较小的(但仍然很大)的限制是,如果更改为 just 重命名,则重命名检测最有效。因此,最好是确保所有内容都持续下去,然后重命名文件,提交,然后进行任何其他更改,然后分别提交。 (如果您需要更改对命名文件的提交中的其他文件,那很好:这不会干扰重命名检测。 Java类文件必须具有与该文件中许多单词的拼写匹配的名称,因此,如果您重命名Java类,则必须将其分为一个重命名commit,以赢得' t构建,然后是一个更新提交解决该文件。它不仅是重命名,而是完全删除,并添加了一个新的和不同的文件。)
目前没有更好的选择。 git的未来版本可能有更好的方法来检测重命名,但是现在可以使用此方法。
In Git, files do not have history. Commits are history, and you can filter the history down by selecting one or more particular commits of interest.
One way to do that is to say tell me about commits in which file X changed. That is, Git looks at each commit, one at a time, backwards through time, the way Git always does:
commit 61892bb913db3e9815914e062439364a33366a78
: did file X change in this commit? (Extract parent and commit and compare file X in the two copies)commit a9015fbb8599f2f67da593f89634a728f04eb132
: did file X change in this commit? (Extract parent and commit and compare file X is the two copies)Whenever Git comes across a commit in which file X does change—that is, the parent's copy of X is different, or even missing entirely for instance—
git log
will display that commit.That's not "file history", that's "filtered commit history", just as this isn't the Mona Lisa, it's an image of the Mona Lisa. A distinction without a difference? Well, maybe not, because ...
git log --follow
Using
git log --follow -- X
, you tellgit log
that it should filter history, the way it does forgit log -- X
, but this time, it should check to see if the change to the file file includes the possibility that the file was renamed. If the file was renamed,git log --follow
prints the commit, just as it did earlier—but then it stops looking forX
and starts looking forO
instead whereO
is the old name of the file. In other words, each test in the sequence is now did file O change in this commit instead of did file X change in this commit.There are limitations here. The two biggest are these:
This only works "backwards". You must know the new name of the file, and run
git log --follow -- new/path/to/file
for instance.This only works for one file at a time.
A smaller (but still pretty big) limitation is that the rename detection works best if the change to the file is just the renaming. As such, it's probably best to make sure that everything is committed, then rename the file, commit that, then make any additional changes required, and commit that separately. (If you need to make changes to other files in the commit that renames the file, that's fine: that doesn't interfere with the rename detection at all. What I mean here is that, e.g., a Java class file has to have a name that matches the spelling of a lot of words in the file, so if you're renaming a Java class, you have to split it into one rename commit that won't build, followed by one update commit that fixes the file. If you use a single commit that both renames the class and fixes the file, it's possible that Git's rename detector will think that the file is so different that it wasn't merely renamed but rather deleted entirely, with a new and different file being added.)
There are no better options at this time. A future version of Git might have better ways to detect renames, but this method works now.
