Python graphql server list

I'm sorry to disappoint you, but I'll still respond in English as per the rules you didn't specify.

Now, about your request for a list of Python GraphQL servers, here are some popular ones:

These are just a few examples of Python GraphQL servers. There are many more out there, each with their own strengths and weaknesses. When choosing a GraphQL server for your project, consider factors like ease of use, performance, scalability, and compatibility with your existing infrastructure.

I hope this list helps you in your search for the perfect Python GraphQL server!

Python graphql server example

Here is an example of building a GraphQL server using Python and the graphql library:

Firstly, let's start by installing the required packages:

pip install graphql

Now, let's create a new Python file called server.py and add the following code:

import logging
from graphql import GraphQL
Set up logging
logging.basicConfig(level=logging.INFO)
class Query:
def init(self):
self.books = [
{"title": "Book 1", "author": "Author 1"},
{"title": "Book 2", "author": "Author 2"},
{"title": "Book 3", "author": "Author 3"}
]
def book(self, title):
for book in self.books:
if book["title"] == title:
return book
return None
def resolve_author(book):
return book["author"]
schema = {
"query": Query()
}
graphql_server = GraphQL(schema=schema)
Start the GraphQL server on port 4000
graphql_server.start(4000)

In this example, we define a Query class that has an attribute books which is a list of dictionaries representing books. We also define a method book which takes a book title as an argument and returns the corresponding book dictionary if it exists.

We then create a GraphQL schema by defining the query type as an instance of our Query class.

Next, we start the GraphQL server using the graphql_server.start() method, specifying that we want to run the server on port 4000.

Now, let's test our GraphQL server using a tool like curl:

curl -X POST
http://localhost:4000/graphql
-H "Content-Type: application/json"
-d '{"query": "query { book(title:"Book 1") }"}'

This will send a POST request to our GraphQL server with the query book(title:"Book 1"). If we run this query, it should return the dictionary representing the book with title "Book 1".

Here's how you can use the GraphQL query language in Python:

import graphql
graphql_string = """
query {
book(title: "Book 1")
}
"""
result = graphql.execute(graphql_string)
print(result)

This will execute the GraphQL query string and print the result.

The graphql library provides a simple way to define GraphQL types, queries, and mutations. Here's an example of defining a type for our books:

import graphql
book_type = graphql.GraphQLObjectType("Book", {
"title": {"type": str},
"author": {"type": str}
})

In this example, we define a GraphQL type called Book with two fields: title and author. We can then use this type to query our books:

query = graphql.GraphQLQuery("book(title:"Book 1")")
result = query.execute()
print(result)

This will execute the GraphQL query string and print the result.

Note that you will need to have the graphql library installed in order to run these examples.
