我试图在python中拆分此字符串: 2.7.0_bf4fda703454

我想在下划线上拆分该字符串,_以便我可以使用左侧的值.

在MySQL中,无法为特定数据库指定存储引擎,仅针对单个表.但是,您可以指定在一个会话期间使用的存储引擎:

SET storage_engine=InnoDB;

因此,您不必为每个表指定它.

如果确实所有表都使用InnoDB,我如何确认？

就像是:

import fileinput

for lines in fileinput.FileInput("test.txt", inplace=1):
    lines = lines.strip()
    if lines == '': continue
    print lines

但是在stdout上没有印刷任何东西.

假设一些字符串命名为foo:

foo.lstrip() # to remove leading white space
foo.rstrip() # to remove trailing whitespace
foo.strip()  # to remove both lead and trailing whitespace

在尝试安装opennms时:

/usr/share/opennms/bin/install -l /usr/local/lib -dis

我收到错误:

错误:编码UTF8与区域设置en_US不匹配详细信息:所选的LC_CTYPE设置需要编码LATIN1.

我不知道如何继续,因为我尝试了几种不同的方式创建数据库(见下文).

有没有办法计算由nosetests运行的单个Python测试的执行时间？

这是安装的标准输出:

        err = ferr.read()
    finally:
        fout.close()
        ferr.close()
    return ret, out, err 

运行此代码时,出现错误:

AttributeError: StringIO instance has no attribute 'fileno'

为什么我会收到此错误,如何更正错误？

我收到错误:ValueError:当我现在运行单元测试时需要超过2个值才能解压缩,所以2个失败,一个跳过现在我已经阅读过

lambda i: get_error_count(self._error_lookup, i))

源的第142行是方法

for test, err, capt in errors:

它有代码行:

count = get_error_count(i)

参考 Python 3.0有点像这样.可以将多余的值绑定(作为列表)到最后一个变量:

a,b,*c = [1,2,3,4,5]

将导致c包含[3,4,5].

在Python 2.x中,你不能直接这样做,但你应该能够创建一个函数,将参数的输入元组延长或缩短到正确的长度,这样你就可以:

a,c,b = fix(1,2)
d,e,f = fix(1,2,3,4)

但是,该函数不会知道左侧序列的长度,因此必须作为额外参数传递或硬编码.

所以

count = get_error_count(i)
uses only one variable, where as
def get_error_count(lookup, index):
takes on 2

我应该用什么作为第二个变量？解决这个问题？

谢谢,-Kamal.

我在尝试查询mergeinfo时遇到此错误.

$ svn mergeinfo --show-revs eligible  https://svn.hq.corp/trunk  https://svn.hq.corp/branches/RC-1

我想要完成的是跟踪分支机构的修订

我正在尝试使用puppet安装特定的rpm,我的init.pp是:

class nmap {
  package {'nmap':
    provider => 'rpm',
    source => "<Local PATH to the RPM>",
  }
}

并且rpm在 ...modules/nmap/files

如果我将rpm移动到清单,并在source =>''中提供rpm名称

class nmap {
  package {'nmap':
    provider => 'rpm',
    source => "rpm-name.rpm",
  }
}

它有效,但我如何指定源路径../files/和成功应用木偶

当我使用:

source => 'puppet:///files/nmap-6.45-1.x86_64.rpm',

我收到一个错误:
