Sure, let's dive into both topics!#### Python Code:
Using Keras, a high-level deep learning library, here's an example of creating a simple RNN:

```python
from keras.models import Sequential
from keras.layers import SimpleRNN, Dense
import numpy as np

# Generating sample sequential data
data = np.random.randn(100, 10, 1)  # Replace this with your sequence data

# Creating the RNN model
model = Sequential()
model.add(SimpleRNN(32, input_shape=(10, 1)))  # Change input_shape and units
model.add(Dense(1))  # Output layer, change units for specific task

# Compiling the model
model.compile(optimizer='adam', loss='mse')  # Define optimizer and loss function

# Training the model
model.fit(data, labels, epochs=10, batch_size=32)  # Replace labels with target data
```

These examples provide a starting point for implementing anomaly detection and building a simple RNN in Python.#### Python Code:

```python
from sklearn.ensemble import IsolationForest
import numpy as np

# Generating sample data
data = np.random.randn(100, 2)  # Replace this with your dataset

# Training the model
model = IsolationForest(contamination=0.1)  # Change the contamination parameter
model.fit(data)

# Predicting anomalies (1 for normal, -1 for anomaly)
predictions = model.predict(data)
print(predictions)
```
