Certainly! Let's begin with querying MongoDB using Kotlin and the Kotlin drivers.

### Querying MongoDB using Kotlin:

1. **Setup**:
   - First, add the MongoDB Kotlin driver dependency to your `build.gradle.kts` or `build.gradle`:
     ```kotlin
     implementation("org.mongodb.kotlin:mongodb-kotlin-driver:VERSION")
     ```

2. **Connecting to MongoDB**:
   ```kotlin
   import org.litote.kmongo.KMongo

   fun main() {
       val client = KMongo.createClient() // by default connects to localhost:27017
       val database = client.getDatabase("mydb")
       val collection = database.getCollection<User>()
   }

   data class User(val name: String, val age: Int)
   ```

3. **Querying**:
   ```kotlin
   // Find all users
   val allUsers = collection.find().toList()

   // Find user by condition
   val usersAbove30 = collection.find(User::age gt 30).toList()

   // Insert user
   collection.insertOne(User("Alice", 25))
   ```

Now, let's move on to the key differences between Kotlin and Python:

### Kotlin vs Python:

1. **Language Type**:
   - **Kotlin**: Statically typed language.
   - **Python**: Dynamically typed language.

2. **Performance**:
   - **Kotlin**: Generally faster than Python because it compiles to bytecode (for the JVM) or machine code (when using Kotlin/Native).
   - **Python**: Interpreted language, usually slower than compiled languages.

3. **Syntax**:
   - **Kotlin**: Has a more concise syntax than Java and provides several features for more concise code. It integrates null safety and extension functions.
   - **Python**: Known for its clean and readable syntax which emphasizes code readability.

4. **Platform & Usage**:
   - **Kotlin**: Primarily used for Android app development, but it's also used for backend development, especially with frameworks like Ktor. Kotlin can be compiled to JVM bytecode, JavaScript, and native code.
   - **Python**: Widely used in web development, data science, artificial intelligence, scientific computing, and scripting. 

5. **Null Safety**:
   - **Kotlin**: Designed with null safety in mind. It distinguishes nullable and non-nullable types, reducing the chances of null pointer exceptions.
   - **Python**: Doesn't have built-in null safety, but uses `None` as its null value.

6. **Frameworks & Libraries**:
   - **Kotlin**: Benefits from Java's rich ecosystem, like Spring, plus its own libraries and frameworks like Ktor.
   - **Python**: Has a vast ecosystem with frameworks like Django, Flask, and libraries like NumPy, TensorFlow, and Pandas for various domains.

7. **Community & Support**:
   - **Kotlin**: While its community is growing rapidly, especially among Android developers, it's smaller than Python's.
   - **Python**: Has a vast and active community, which results in a plethora of resources, tools, and libraries.

Both languages have their strengths and are suited for different purposes. Your choice between them should depend on the specific needs of your project.
