• Python: Converting legacy string dates to dates

  - by Eric

  We have some legacy string dates that I need to convert to actual dates that can be used to perform some date logic. Converting to a date object isn't a problem if I knew what the format were! That is, some people wrote 'dd month yy', othes 'mon d, yyyy', etc. So, I was wondering if anybody knew of a py module that attempts to guess date formats and rewrites them in a uniform way? Any other suggestions? Thanks! :) Eric

• Use string value to create new instance

  - by Brian David Berman

  I have a few classes: SomeClass1, SomeClass2. How can I create a new instance of one of these classes by using the class name from a string? Normally, I would do: var someClass1 = new SomeClass1(); How can I create this instance from the following: var className = "SomeClass1"; I am assuming I should use Type.GetType() or something but I can't figure it out. Thanks.

• Linux: shell builtin string matching

  - by gmatt

  I am trying to become more familiar with using the builtin string matching stuff available in shells in linux. I came across this guys posting, and he showed an example a="abc|def" echo ${a#*|} # will yield "def" echo ${a%|*} # will yield "abc" I tried it out and it does what its advertised to do, but I don't understand what the $,{},#,*,| are doing, I tried looking for some reference online or in the manuals but I couldn't find anything. Can anyone explain to me what's going on here?

• How can I create an fscanf format string to accept white space and comma (,) tokenization

But in the situation where I've got data files that are separated by commas, I'm currently doing something like: sed 's/,/ /g' data | myprog Can I modify the format string in the fscanf() function to accept both delimitation formats?

• PHP: Simple, Validate if string is hex?

  - by oni-kun

  I have no clue how to validate this string. I am simply supplying an IV for an encryption, but can find no "is_hex()" or similar function, I can't wrap my head around it! I read on a comment in the php documentation (user contrib. notes) this: if($iv == dechex(hexdec($iv))) { //True } else { //False } But that doesn't seem to work at all.. It only says false. If it helps my input of my IV would be this: 92bff433cc639a6d

• Getting a specific bit value in a byte string

  - by ignoramus

  There is a byte at a specific index in a byte string which represents eight flags; one flag per bit in the byte. If a flag is set, its corresponding bit is 1, otherwise its 0. For example, if I've got b'\x21' the flags would be 0001 0101 # Three flags are set at indexes 3, 5 and 7 # and the others are not set What would be the best way to get each bit value in that byte, so I know whether a particular flag is set or not? (Preferably using bitwise operations)
