+# simple_api_call
+
+1. Write a Function to Make an API Call:
+
+    You have a Python module called weather.py that includes a function get_weather() that fetches weather data from a hypothetical API. Tip: To make api calls in Python. Check how to use the "requests" library in python.
+
+2. Write Tests and Mock the API Call:
+Create a test file called test_weather.py. In this file, you’ll the "requests.get" function so that no real HTTP request is made.
+
+Tip: Learn how to use unittest.mock and patch. A link has been attached for your reference.
