Generate Key Value Pair From List
Takes dictionaries as input and returns a list with each item in the list being a dictionary with ‘key’ and ‘value’ as keys to the previous dictionary’s structure. Dictionary in Python is an unordered collection of data values, used to store data values like a map, which unlike other Data Types that hold only single value as an element, Dictionary holds key:value pair. While using Dictionary, sometimes, we need to add or modify the key/value inside the dictionary.
- You can have up to five thousand key pairs per Region. The key pair returned to you is available only in the Region in which you create it. If you prefer, you can create your own key pair using a third-party tool and upload it to any Region using ImportKeyPair. For more information, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.
- Working with Key/Value Pairs Become a Certified Professional As part of this Spark tutorial, you will get to know what a key/value pair is, how to create pair RDDs and transformations in pair RDDs, what actions are available in pair RDDs, how to do data partitioning, custom partitioning, and so much more.
- Creating an SSH Key Pair for User Authentication. The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39) ssh-keygen Generating public/private rsa key pair.
- Here we create a List that stores elements of type KeyValuePair. Notice how the (Of String, Integer) syntax is used to specify that the key of the pair is a String, and the value is an Integer.List Strings Integer. Note: When creating a KeyValuePair, you must set the key and the value in the constructor.
- Your outer JSON container is an array, so you need to return some sort of non-dictionary collection such as a List for your root object, like so.
Definition
Defines a key/value pair that can be set or retrieved.
Type Parameters
- TValue
The type of the value.
- Attributes
Examples
The following code example shows how to enumerate the keys and values in a dictionary, using the KeyValuePair<TKey,TValue> structure.
This code is part of a larger example provided for the Dictionary<TKey,TValue> class.
Remarks
The Dictionary<TKey,TValue>.Enumerator.Current property returns an instance of this type.
The foreach statement of the C# language (for each in C++, For Each in Visual Basic) returns an object of the type of the elements in the collection. Since each element of a collection based on IDictionary<TKey,TValue> is a key/value pair, the element type is not the type of the key or the type of the value. Instead, the element type is KeyValuePair<TKey,TValue>. For example:
The foreach statement is a wrapper around the enumerator, which allows only reading from, not writing to, the collection.
Constructors
| KeyValuePair<TKey,TValue>(TKey, TValue) | Initializes a new instance of the KeyValuePair<TKey,TValue> structure with the specified key and value. |
Properties
| Key | Gets the key in the key/value pair. |
| Value | Gets the value in the key/value pair. |
Methods
| Deconstruct(TKey, TValue) | |
| ToString() | Returns a string representation of the KeyValuePair<TKey,TValue>, using the string representations of the key and value. |

Description¶
Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#1 private key. If a key with the specified name already exists, Amazon EC2 returns an error.
You can have up to five thousand key pairs per Region.
The key pair returned to you is available only in the Region in which you create it. If you prefer, you can create your own key pair using a third-party tool and upload it to any Region using ImportKeyPair .

Synopsis¶
Options¶
--key-name (string)
A unique name for the key pair.
Constraints: Up to 255 ASCII characters
--dry-run--no-dry-run (boolean)
--cli-input-json (string)Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. Terminal generate key tron crypto. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton (string)Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
