- regex - Matching strings in PowerShell - Stack Overflow
I'm trying to match the file names against the recorded names in my CSV file It generally works, but sometimes I get incorrect matches Let's say I have two files that start similarly, Apple and Apple_Pie Apple will match to Apple and move to the right directory, but Apple_Pie will first match to Apple and move to the wrong directory
- Regex: ignore case sensitivity - Stack Overflow
G[a-b] * i string match("G[a-b] *", "i") Check the documentation for your language platform tool to find how the matching modes are specified If you want only part of the regex to be case insensitive (as my original answer presumed), then you have two options:
- OR condition in Regex - Stack Overflow
For example, ab|de would match either side of the expression However, for something like your case you might want to use the ? quantifier, which will match the previous expression exactly 0 or 1 times (1 times preferred; i e it's a "greedy" match) Another (probably more relyable) alternative would be using a custom character group:
- Reset local repository branch to be just like remote repository HEAD
Setting your branch to exactly match the remote branch can be done in two steps: git fetch origin git reset --hard origin master If you want to save your current branch's state before doing this (just in case), you can do: git commit -a -m "Saving my work, just in case" git branch my-saved-work
- If two cells match, return value from third - Stack Overflow
=INDEX(B:B,MATCH(C2,A:A,0)) I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B
- Check whether a cell contains a substring - Stack Overflow
Another note of importance is that IFS will return the match that it finds first and thus ordering is important For example if my strings were Surf, Surfing, Surfs as String1,String2,String3 above and my cells string was Surfing it would match on the first term instead of the second because of the substring being Surf Thus common denominators
- How to use - Stack Overflow
Start of String ancor \A, alternatively use the ^ caret to match postion before 1st char in string; End of String ancor \Z, alternatively use the $ dollar sign to match postion after last char in string; Positive LookBehind, e g : (?<=a)b (whilst postive LookAhead is supported) Negative LookBehind, e g : (?<!a)b (whilst negative LookAhead is
- How can I compare two lists in python and return matches
A quick performance test showing Lutz's solution is the best: import time def speed_test(func): def wrapper(*args, **kwargs): t1 = time time() for x in xrange(5000): results = func(*args, **kwargs) t2 = time time() print '%s took %0 3f ms' % (func func_name, (t2-t1)*1000 0) return results return wrapper @speed_test def compare_bitwise(x, y): set_x = frozenset(x) set_y = frozenset(y) return set
