背景

多年的技术开发，积累了很多关于Python的常⽤的⼀些函数和功能，都已整理到对应的函数库中：

https://github.com/crifan/crifanLibPython

且也给出了很多函数的demo演示如何使⽤：

https://github.com/crifan/crifanLibPython/tree/master/crifanLib/demo

但还是解释的不够清楚和全⾯。

故此处专⻔把Python的常⽤的代码段和调⽤举例，都整理⾄此，详细解释。

⽬的：

⽅便需要时能快速查阅：直接看代码，⼀看就懂，⽆需额外解释。

通⽤逻辑

多次运⾏⼀个函数，直到成功运⾏

执⾏⼀个函数（可能有多个可变数量的参数），且尝试多次，直到成功或超出最⼤此时，最终实现

是：

说明：

functionCallback函数类型都要符合：返回值是bool类型才可以

调⽤举例：

（1）没有额外参数

foundAndClickedWififoundAndClickedWifi==CommonUtilsCommonUtils..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..iOSFromSettingsIiOSFromSettingsIntoWifiListntoWifiList}}))

其中：

defdefiOSFromSettingsIntoWifiListiOSFromSettingsIntoWifiList((selfself))::。。。。。。

foundAndClickedWififoundAndClickedWifi==selfself..findAndClickElementfindAndClickElement((queryquery==wifiTextQuerywifiTextQuery,,timeouttimeout==0.10.1))returnreturnfoundAndClickedWififoundAndClickedWifi

类似例⼦：

isSwitchOkisSwitchOk==selfself..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..switchToAppStoreSearchTabswitchToAppStoreSearchTab}}))

对⽐之前原始写法：

isSwitchOkisSwitchOk==selfself..switchToAppStoreSearchTabswitchToAppStoreSearchTab(())

其他类似例⼦：

foundAndClickedDownloadfoundAndClickedDownload==selfself..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..appStoreStartDownloappStoreStartDownloadad}}))

详⻅：

【已解决】AppStore⾃动安装iOS的app：逻辑优化加等待和多试⼏次

（2）有额外参数，参数个数：2个

searchInputQuerysearchInputQuery=={{"type""type"::"XCUIElementTypeSearchField""XCUIElementTypeSearchField",,"name""name"::"AppStore""AppStore"}}isInputOkisInputOk==CommonUtilsCommonUtils..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..wait_element_setTextwait_element_setText,,"functionParaDict""functionParaDict"::{{"locator""locator"::searchInputQuerysearchInputQuery,,"text""text"::appNameappName,,}}}}))

对⽐之前原始写法：

searchInputQuerysearchInputQuery=={{"type""type"::"XCUIElementTypeSearchField""XCUIElementTypeSearchField",,"name""name"::"AppStore""AppStore"}}isInputOkisInputOk==selfself..wait_element_setTextwait_element_setText((searchInputQuerysearchInputQuery,,appNameappName))

其中wait_element_setText的定义是：

defdefwait_element_setTextwait_element_setText((selfself,,locatorlocator,,texttext))::

对应着之前传⼊时的：

"functionParaDict""functionParaDict"::{{"locator""locator"::searchInputQuerysearchInputQuery,,"text""text"::appNameappName,,}}

（3）有额外参数，且加上multipleRetry的额外参数

isSwitchOkisSwitchOk==CommonUtilsCommonUtils..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..switchToAppStoreSearchTabswitchToAppStoreSearchTab}},,maxRetryNummaxRetryNum==1010,,sleepIntervalsleepInterval==0.50.5,,))

以及类似的：

isIntoDetailOkisIntoDetailOk==selfself..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..appStoreSearchResultIntoDetailappStoreSearchResultIntoDetail,,"functionParaDict""functionParaDict"::{{"appName""appName"::appNameappName,,}}}},,sleepIntervalsleepInterval==0.50.5))

之前原始写法：

isIntoDetailOkisIntoDetailOk==selfself..appStoreSearchResultIntoDetailappStoreSearchResultIntoDetail((appNameappName))

注：

此处是后来加上的

sleepInterval=0.5

是因为后来遇到了，即使尝试了5次，依旧没找到，所以增加了没找到的延迟等待时间。

新版：新增参数isRespFullRetValue

此处最后更新： 20200925

后续多次优化新增参数：是否返回完整信息

代码：

字符和字符串

详⻅：

https://github.com/crifan/crifanLibPython/blob/master/crifanLib/crifanFile.py

Python3str转bytes

Python3中，把字符串转换成字节码，可以有两种写法：

⽅法1：⽤bytes去转换

convertedBytesconvertedBytes==bytesbytes((originStroriginStr))

⽅法2：⽤字符串str的编码encode

encodedBytesencodedBytes==originStroriginStr..encodeencode(())

其中：

都有额外的encoding参数：

由于默认都是UTF-8所以可加可不加

也可以根据需要，去加其他你要的编码

如果要加，就是：

convertedBytesconvertedBytes==bytesbytes((originStroriginStr,,"UTF-8""UTF-8"))encodedBytesencodedBytes==originStroriginStr..encodeencode(("UTF-8""UTF-8"))

字符串格式化为⼈类易读格式

通过⼆进制⽣成⽂件类型对象

（1）Python3

importimportioio

audioBinaryDataaudioBinaryData==audioObjaudioObj..readread(())audioFileLikeObjaudioFileLikeObj==ioio..BytesIOBytesIO((audioBinaryDataaudioBinaryData))

得到对应的⽂件类型的对象的： <_io.BytesIOobjectat0x115964468>，即可去像操作⽂件⼀样去操

作这个io。

（2）Python2

importimportStringIOStringIO

audioFileLikeObjaudioFileLikeObj==StringIOStringIO..StringIOStringIO(())audioFileLikeObjaudioFileLikeObj..writewrite((audioBinaryDataaudioBinaryData))

⼀⾏代码把字符串写⼊保存到⽂件

播放⾳频

树莓派中⽤python播放⾳频

前提：

树莓派中，先去安装vlc：

sudosudoapt-getapt-getinstallinstallvlcvlc

代码：

importimportvlcvlcinstanceinstance==vlcvlc..InstanceInstance(('--aout=alsa''--aout=alsa'))pp==instanceinstance..media_player_newmedia_player_new(())mm==instanceinstance..media_newmedia_new(('/home/pi/Music/lizhongsheng_massif_live.mp3''/home/pi/Music/lizhongsheng_massif_live.mp3'))pp..set_mediaset_media((mm))pp..playplay(())

即可播放⾳频。

实现设置⾳量，暂停，继续播放等操作的代码是：

pp..pausepause(())vlcvlc..libvlc_audio_set_volumelibvlc_audio_set_volume((pp,,4040))pp..playplay(())vlcvlc..libvlc_audio_set_volumelibvlc_audio_set_volume((pp,,9090))

Mac中调⽤mpv播放⾳频

播放⾳频：

cmdPlayercmdPlayer=="mpv""mpv"cmdParaFilePathcmdParaFilePath==tmpAudioFileFullPathtmpAudioFileFullPathcmdArgListcmdArgList==[[cmdPlayercmdPlayer,,cmdParaFilePathcmdParaFilePath]]

⽹络相关

107


BeautifulSoup

⽤⽹络库下载到⻚⾯源码后，就是去解析（HTML等）内容了。

Python中最常⽤的HTML（和XML）解析库之⼀就是： BeautifulSoup

从xml转换出soup

背景：

iOS⾃动化期间，常会涉及到，获取到当前⻚⾯源码，是xml字符串，需要转换为soup，才能后续操作

所以整理出通⽤转换逻辑

defdefxmlToSoupxmlToSoup((xmlStrxmlStr))::"""converttoxmlstringtosoup"""converttoxmlstringtosoupNote:xmlistagcasesensitive->retaintaguppercase->NOTconverttagtolowNote:xmlistagcasesensitive->retaintaguppercase->NOTconverttagtolowercaseercase

举例：

（1）

curPageXmlcurPageXml==selfself..get_page_sourceget_page_source(())soupsoup==CommonUtilsCommonUtils..xmlToSoupxmlToSoup((curPageXmlcurPageXml))

获取到xml字符串后，去转换为soup

说明：

判断soup内，是否有符合特定条件的soup

举例：

（1）iOS的弹框，有上⻆带关闭按钮时，去判断⼀个弹框，是否符合对应条件，以便于判断是否可能

查找元素，限定条件是符合对应的⼏级的⽗元素的条件

背景：

很多时候，需要对于iOS的app的⻚⾯的源码，即xml中，查找符合特定情况的的元素

这些特定情况，往往是parent或者前⼏层级的parent中，元素符合⼀定条件，往往是type，以及宽度是

屏幕宽度，⾼度是屏幕⾼度等等

所以提取出公共函数，⽤于bs的find查找元素

其中的：

functionCallback(**functionParaDict)

中的：

**functionParaDict

函数参数

121

表示，dict类型的参数，内部包含多个key和value，⽤**去展开后，传⼊真正要执⾏的函数

⼏种调⽤中带参数的例⼦是：

searchInputQuerysearchInputQuery=={{"type""type"::"XCUIElementTypeSearchField""XCUIElementTypeSearchField",,"name""name"::"AppStore""AppStore"}}isInputOkisInputOk==selfself..multipleRetrymultipleRetry(({{"functionCallback""functionCallback"::selfself..wait_element_setTextwait_element_setText,,"functionParaDict""functionParaDict"::{{"locator""locator"::searchInputQuerysearchInputQuery,,"text""text"::appNameappName,,}}}}))

之前原始写法：

searchInputQuerysearchInputQuery=={{"type""type"::"XCUIElementTypeSearchField""XCUIElementTypeSearchField",,"name""name"::"AppStore""AppStore"}}isInputOkisInputOk==selfself..wait_element_setTextwait_element_setText((searchInputQuerysearchInputQuery,,appNameappName))

其中wait_element_setText的定义是：

defdefwait_element_setTextwait_element_setText((selfself,,locatorlocator,,texttext))::

对应着之前传⼊时的：

"functionParaDict""functionParaDict"::{{"locator""locator"::searchInputQuerysearchInputQuery,,"text""text"::appNameappName,,}}

即可，给出上述细节，便于理解，传⼊的参数是如何⽤ **展开的。

dict字典

删除dict中某个键（和值）

常⻅写法：

deldelyourDictyourDict[["keyToDelete""keyToDelete"]]

更加Pythonic的写法：

yourDictyourDict..poppop(("keyToDelete""keyToDelete"))

注意：

为了防⽌出现 KeyError，注意确保要删除的key都是存在的，否则就要先判断存在，再去删除。

OrderedDict

想要获取OrderedDict的最后⼀个item（的key和value）

nextnext((reversedreversed((someOrderedDictsomeOrderedDict..itemsitems(())))))

另外，只需要获取最后⼀个元素的key，则可以：

nextnext((reversedreversed((someOrderedDictsomeOrderedDict..keyskeys(())))))

或：

nextnext((reversedreversed((someOrderedDictsomeOrderedDict))))

（1）如果⽆需保留原有（第⼀个dict）的值，则⽤update即可：

enum枚举

枚举基本⽤法

枚举定义

举例1：

fromfromenumenumimportimportEnumEnum

classclassBatteryStateBatteryState((EnumEnum))::UnknownUnknown==00UnpluggedUnplugged==11ChargingCharging==22FullFull==33

举例2：

importimportenumenum

classclassScreenshotQualityScreenshotQuality((enumenum..EnumEnum))::OriginalOriginal==00MediumMedium==11LowLow==22

举例3：

classclassSentenceInvalidReasonSentenceInvalidReason((EnumEnum))::NONENONE=="none""none"UNKNOWNUNKNOWN=="unknown""unknown"EMPTYEMPTY=="empty"emptyTOO_SHORTTOO_SHORT=="tooshort""tooshort"TOO_LONGTOO_LONG=="toolong""toolong"TOO_MANY_INVALID_WORDTOO_MANY_INVALID_WORD=="containtoomanyinvalidwords""containtoomanyinvalidwords"

初始化创建枚举值

直接传⼊对应的（此处是int）值即可：

batteryStateIntbatteryStateInt==22curBattryStateEnumcurBattryStateEnum==BatteryStateBatteryState((batteryStateIntbatteryStateInt))

log输出是：

curBattryStateEnumcurBattryStateEnum==BatteryState.ChargingBatteryState.Charging

enum枚举

135

获取枚举的名称

curBattryStateNamecurBattryStateName==curBattryStateEnumcurBattryStateEnum..namename

输出： 'Charging'

获取枚举的值

curBattryStateValuecurBattryStateValue==curBattryStateEnumcurBattryStateEnum..valuevalue

输出： 2

类似，直接从定义中获取值：

gScreenQualitygScreenQuality==ScreenshotQualityScreenshotQuality..LowLow..valuevalue#2#2

枚举⾼级⽤法

给枚举中添加函数

classclassTipTypeTipType((enumenum..EnumEnum))::NoTipNoTip=="NoTip""NoTip"TenPercentTenPercent=="TenPercent""TenPercent"FifthPercentFifthPercent=="FifthPercent""FifthPercent"TwentyPercentTwentyPercent=="TwentyPercent""TwentyPercent"

#@property#@propertydefdefgetTipPercentgetTipPercent((selfself))::tipPercenttipPercent==0.00.0ififselfself====TipTypeTipType..NoTipNoTip::tipPercenttipPercent==0.00.0elifelifselfself====TipTypeTipType..TenPercentTenPercent::tipPercenttipPercent==0.100.10elifelifselfself====TipTypeTipType..FifthPercentFifthPercent::tipPercenttipPercent==0.150.15elifelifselfself====TipTypeTipType..TwentyPercentTwentyPercent::tipPercenttipPercent==0.200.20gLoggLog..debugdebug(("self=%s->tipPercent=%s""self=%s->tipPercent=%s",,selfself,,tipPercenttipPercent))returnreturntipPercenttipPercent

调⽤：

tipPercenttipPercent==initiatorTipTypeinitiatorTipType..getTipPercentgetTipPercent(())#tipPercent=0.1#tipPercent=0.1

enum枚举

136

注意事项

字符串枚举定义最后不要加逗号

enum定义期间不要加（多余的）逗号：

classclassScreenshotQualityScreenshotQuality((enumenum..EnumEnum))::OriginalOriginal==00,,MediumMedium==11,,LowLow==22,,

否则 value就是 tuple元祖了：

gScreenQualitygScreenQuality==ScreenshotQualityScreenshotQuality..LowLow..valuevalue##实际上是实际上是(2,)(2,)printprint(("gScreenQuality=%s""gScreenQuality=%s"%%gScreenQualitygScreenQuality))#gScreenQuality=2#gScreenQuality=2printprint(("type(gScreenQuality)=%s""type(gScreenQuality)=%s"%%typetype((gScreenQualitygScreenQuality))))#type(gScreenQuality)=<class'tup#type(gScreenQuality)=<class'tuple'>le'>

collections集合

根据官⽹：

collections---容器数据类型—Python3.8.1⽂档

介绍，集合有很多种，列出供了解：

namedtuple()：创建命名元组⼦类的⼯⼚函数

deque：类似列表(list)的容器，实现了在两端快速添加(append)和弹出(pop)ChainMap：类似字典(dict)的容器类，将多个映射集合到⼀个视图⾥⾯

Counter：字典的⼦类，提供了可哈希对象的计数功能

OrderedDict：字典的⼦类，保存了他们被添加的顺序

defaultdict：字典的⼦类，提供了⼀个⼯⼚函数，为字典查询提供⼀个默认值

UserDict：封装了字典对象，简化了字典⼦类化

UserList：封装了列表对象，简化了列表⼦类化

UserString：封装了列表对象，简化了字符串⼦类化

待以后⽤到了，再详细总结。
