# Extract strings with a specific regex df= df['col_name'].str.extract[r'[Aa-Zz]'] # Replace strings within a regex df['col_name'].str.replace('Replace this', 'With this') For information on how to match strings using regex, see Getting started with Regular Expressions.

Active patterns are just simple functions. Like functions you can define additional parameters: let (|HasExtension|_|) expected (uri : string) = let result = uri.EndsWith (expected, StringComparison.CurrentCultureIgnoreCase) match result with | true -> Some true | _ -> N...

The plotly package allows many kind of interactive plots, including maps. There are a few ways to create a map in plotly. Either supply the map data yourself (via plot_ly() or ggplotly()), use plotly's "native" mapping capabilities (via plot_geo() or plot_mapbox()), or even a combination o...

Fortran 2003 introduced support for object oriented programming. This feature allows to take advantage of modern programming techniques. Derived types are defined with the following form: TYPE [[, attr-list] :: ] name [(name-list)] [def-stmts] [PRIVATE statement or SEQUENCE statement]. . . ...

C++11 std::string supports iterators, and so you can use a ranged based loop to iterate through each character: std::string str = "Hello World!"; for (auto c : str) std::cout << c; You can use a "traditional" for loop to loop through every character: std::stri...

Starting with Asp.net 4.5 web controls can take advantage from strongly-typed binding to get IntelliSense support and compiletime errors. Create a class, which holds your model: public class Album { public int Id { get; set; } public string Name { get; set; } public string Artist {...

Converting an NSDate object to string is just 3 steps. 1. Create an NSDateFormatter object Swift let dateFormatter = NSDateFormatter() Swift 3 let dateFormatter = DateFormatter() Objective-C NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 2. Set the date format in whic...

You can use Gradle to auto-increment your package version each time you build it. To do so create a version.properties file in the same directory as your build.gradle with the following contents: VERSION_MAJOR=0 VERSION_MINOR=1 VERSION_BUILD=1 (Changing the values for major and minor as you s...

int squareNum (int a) { return a*a; } int : return type squareNum : function name int a : parameter type and name return a*a : return a value (same type as the return type defined at the beginning)

If you have a function declared you can call it anywhere else in the code. Here is an example of calling a function: void setup(){ Serial.begin(9600); } void loop() { int i = 2; int k = squareNum(i); // k now contains 4 Serial.println(k); delay(500); } int squareNum(int a)...

Given the following definitions : public interface IMyInterface1 { string GetName(); } public interface IMyInterface2 { string GetName(); } public class MyClass : IMyInterface1, IMyInterface2 { string IMyInterface1.GetName() { return "IMyInterface1"...
