AttributeError: module 'tensorflow_federated.python.learning' has no attribute 'algorithms'

I am trying to run the code given by Tensorflow in their official documentation, pertaining to Tensorflow-Federated. The code is as follows:

import tensorflow as tf
import tensorflow_federated as tff

def model_fn():
  model = tf.keras.models.Sequential([
      tf.keras.layers.Dense(10, tf.nn.softmax, input_shape=(784,),
                            kernel_initializer='zeros')
  ])

trainer = tff.learning.algorithms.build_weighted_fed_avg(
  model_fn,
  client_optimizer_fn=lambda: tf.keras.optimizers.SGD(0.1))

However, I am getting the following error:

Traceback (most recent call last):
  File "G:/pythonproject2/main.py", line 43, in <module>
    trainer = tff.learning.algorithms.build_weighted_fed_avg(
AttributeError: module 'tensorflow_federated.python.learning' has no attribute 'algorithms'

Could someone please help me out?

I found the issue, tensorflow_federated requires Python 3.9+. Since I was using Python 3.7, I encountered the above error.
