If your addresses are always on the end of a line, then anchor on that: ip_at_end = re.compile(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}$’, re.MULTILINE) This regular expression only matches dotted quads (4 sets of digits with dots in between) at the end of a line. Demo: >>> import re >>> ip_at_end = re.compile(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}$’, re.MULTILINE) >>> example=””‘\ … Only addresses on … Read more
The browser won’t send that information to the server. Since you (presumably) wrote the HTML in the first place, you can keep a record of what values are associated with what labels.

This operator is called the ternary operator. empty works like this: The following things are considered to be empty: – “” (an empty string) – 0 (0 as an integer) – 0.0 (0 as a … Read more
First off, you haven’t set an explicit modifier on the class, so your are going to end up with whatever the default happens to be (if it’s in the namespace then internal or private if contained in a class). This can cause minor inconveniences at compile-time. A bigger issue might be if the default exposes … Read more
If count($arr2) is 26 if(count($arr1) === count($arr2) === 26) evaluates to if(count($arr1) === True) which would then fail. You need to perform two logic checks and check they both evaluate to true 3 solved using count in if statement and comparing with its returned value doesn’t work [closed]
You can run an app with ARKit on an iPhone 6. It won’t crash, but the view will be blank. 2 solved How to run ARKit on iPhone 6 ?
You cannot. Your code has an undefined behavior. If I modify the main() function to: int main() { Person *p = new Person(); Developer* d = dynamic_cast<Developer*>(p); assert(d!=0); d->Pi(); delete p; delete d; return 0; } Then the assertion d!=0 is triggered. That shows that the dynamic_cast failed. You call Developer::Pi on a null pointer, … Read more

You’ll probably need to specify your … Read more
You should not use == when comparing objects including strings. Generally == compares references, so it return true only of same objects. You should use equals() method instead: str1.equals(str2) It occasionally works for you in first case because java caches string constants, so “java” in both cases is represented by same instance of String. solved … Read more
