To calculate the sum of terms (of type float, int or big integer) of a number list, it is preferable to use List.sum
In other cases, List.fold is the function that is best suited to calculate such a sum.
Sum of complex numbers
In this example, we declare a list of complex numbers and we calcu...
Create a new folder called MyClasses and create and add the following class

// Gmail user-name
public string UserName { get; set; }
public GmailEmailService() :

This will be our example data frame:
df = pd.DataFrame({"color": ['red', 'blue', 'red', 'blue']},
index=[True, False, True, False])
color
True red
False blue
True red
False blue
Accessing with .loc
df.loc[True]
color
True red
True red
...
This will be our example data frame:
color name size
0 red rose big
1 blue violet big
2 red tulip small
3 blue harebell small
Using the magic __getitem__ or [] accessor. Giving it a list of True and False of the same length as the dataframe will give you:

First, let's define a sample XML document named "books.xml" in our current directory:
<?xml version="1.0" encoding="UTF-8"?>

You can use any name for the function.
function custom_postype(){
register_post_type('cus_post',array(
'labels'=>array(
'name'=>'khaiyam'// Use any name you want to show in menu for your users
),
'public'=>true,// **Must required
...
Validating the Name entered by a User contain the following check
Ensure it is not empty
Ensure it contain only alphabets, space and/or dot.
So, the regular expression for this is
^[A-Z][a-z]*(\.?\s?[A-Z][a-z]*)+$
This means
^ -> Should start with
[A-Z] -> the first lette...
Sometimes, we have to take input from users which should contain only alpha numeric characters.
For example, lets say a Username system which allow only letters and numbers,
Then this can be done with the following Regular Expression
^[a-zA-Z0-9]+$
^ is restrict the start
[a-zA-Z0-9]+ is th...
Using the previous example of calculating the factorial of an integer, put in the hash table all values of factorial calculated inside the recursion, that do not appear in the table.
As in the article about memoization, we declare a function f that accepts a function parameter fact and a integer pa...
One of the common ways to parametrize your performance scripts is to use a CSV file. The best example of CSV input files usage is a login process. If you want to test your application across different users, you need to provide a list of user credentials.
Let’s assume that we have a login request t...
Another way to parametrize your performance scripts is to use database data through JDBC. JDBC is an application programming interface that defines how a client can access a database.
First of all, download the JDBC driver to your database (refer to the database vendor). For example, mysql driver c...
If you need to execute a repeating sequence of the same action with different parameters, use the ‘Parameterized Controller’ 3rd party plugin from JMeter-Plugins project.

Consider next example:
public interface A {
default void foo() { System.out.println("A.foo"); }
}
public interface B {
default void foo() { System.out.println("B.foo"); }
}
Here are two interfaces declaring default method foo with the same signature.

It is quite easy to call a CGI-Script via GET.
First you will need the encoded url of the script.
Then you add a question mark ? followed by variables.
Every variable should have two sections seperated by =.
First section should be always a unique name for each variable,
while the second part h...
