Python查看已安装库的版本

Python查看已安装库的版本 以查看numpy的版本为例。 目录 一、Linux系统 1、Python2 2、Python3 二、Windows系统 1、Python2 2、Python3 一、Linux系统 1、Python2 pip2 list | grep numpy 运行上面的命令输出： numpy (1.15.4) 1.15.4就是库的版本号。pip list会列出所有安装的库；|是重定向输出符号，把pip list的输出重定为grep命令的输入；grep命令是从输入中找到包含numpy那一行并打印出来，如果没有找到，则没有输出。 2、Python3 pip3 list | grep numpy 二、Windows系统 1、Python2 pip2 list | findstr numpy 运行上面的命令输出： numpy 1.16.2 1.16.2就是版本号。findstr类似于linux系统的grep命令，如果没有找到，则没有输出。 2、Python3 pip3 list | findstr numpy 原文信息： 声明：本文为CSDN博主「原我归来是少年」的原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/DumpDoctorWang/article/details

How to use findstr to search for multiple strings in one line

由 本秂侑毒 提交于 2020-01-14 03:35:09
问题 So I want to be able to search for the string "[ FAILED ]" and the string "." that are both on the same line inside of a text file. How would I do this? I tried this: FINDSTR /C:"[ FAILED ]" /C:"." output_.txt but it produces lines that contain either of the strings. If possible I also want to be able to exclude any lines that contain numbers from my finds. 回答1: I have answered my own question using piping and coming up with the following command: FINDSTR /C:"[ FAILED ]" output_.txt | FINDSTR

Batch Script to delete files based on findstr regex

由 久未见 提交于 2020-01-13 18:08:47
问题 I'm trying to delete some files with a batch script, based on a regular expression. What I have is: FOR /f "tokens=*" %%a in ('dir /b | findstr MY_REGEX_HERE') DO ECHO %%a I know my inner command works on its own, giving me the list of directories, but when I embed it in the for loop like this I get an error | was unexpected at this time. Is piping not allowed within FOR loop commands? Or do I need to escape it or something? Any help on how I can do this would be great. 回答1: FOR /f "tokens=*"

findstr的命令行分析机制

来源：http://www.cn-dos.net/forum/viewthread.php?tid=21167&fpage=1&highlight=findstr willsort 版主 To All: 问题缘起于bsijl一篇关于findstr错误过滤的主题[1]，当时因为无法找到原因，所以只能推测 /g 开关存在某些问题。 近日，因为编写一个debuger代码，再次使用了 findstr/g ，结果遇到了同样的问题[2]。经过仔细的测试[3]后，发现是 findstr 特殊的命令行分析机制所引起的问题。略述如下： 1、findstr不同于早期的find，它对参数的排列有一定的要求，即遵循开关（可省略）、字符串（使用/c开关时省略）、文件名（可通配、可多个、有输入流时需省略）的顺序。 2、开关可以使用引号，所以不能直接以与开关相同的关键字进行搜索；文件名含空格时必须用引号。 3、搜索关键字的情况和表现就比较复杂，分述如下： 3-1、无论是否使用开关/l或/r以及是否使用引号，关键字中的\都会成为转义字符，所以\\将成为\，\"将使引号失去字符串界定作用； 3-2、搜索关键字可加或不加引号，当加引号时其中的\可能会再次转义。使用开关/l和/r时的转义结果可能会不同：当使用/r时，所以"\\\\"将成为单个\，"\\"将使关键字为空；当使用/l或均不使用时，"\\\\"和"\\

Findstr - Return only a regex match

由 二次信任 提交于 2020-01-10 05:02:06
问题 I have this string in a text file ( test.txt ): BLA BLA BLA BLA BLA Found 11 errors and 7 warnings I perform this command: findstr /r "[0-9]+ errors" test.txt In order to get just 11 errors string. Instead, the output is: Found 11 errors and 7 warnings Can someone assist? 回答1: The findstr tool cannot be used to extract matches only. It is much easier to use Powershell for this. Here is an example: $input_path = 'c:\ps\in.txt' $output_file = 'c:\ps\out.txt' $regex = '[0-9]+ errors' select
