Python syntax in Apache Airflow

Question

I'm really new to Apache Airflow and am currently reviewing a Python script in GCP's qwiklabs. I noticed this syntax and I got a bit confused by it:

input_file = input_file = '/home/airflow/gcs/data/rose.txt'

in this chunk of code:

WORDCOUNT_JAR = (
    'file:///usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar'
)

input_file = input_file = '/home/airflow/gcs/data/rose.txt'

wordcount_args = ['wordcount', input_file, output_file]

Why is it input_file = input_file = file_path? What does it mean?

Thanks xD
