Python Weather Forecasting: Build Your Own Application Today!

Weather forecasting is a crucial aspect of our daily lives. It plays a vital role in determining our schedules and daily activities.

From tourism to transportation and farming, weather prediction is essential. As we all know, our lives revolve around the weather.

Therefore, having accurate weather predictions is critical. In this article, we will explore how to create a weather forecasting application using Python.

We will discuss the installation of a request library, the interface for our application, and the implementation of the weather forecasting code. Installing the Request Library:

Before we delve into the implementation of the weather forecasting code, we need to install the requests library.

The request library is an essential module in Python that helps manage HTTP requests. It allows us to send HTTP requests using Python.

To install it, we need to use the pip command. The pip command is a package installer that is used to install, upgrade, and remove Python packages.

User Interface for the Application:

After installing the request library, we can move to the user interface for our application. A user-friendly interface is necessary to make our application easy to navigate.

Therefore, it would be good to have a welcome message that greets the user when they start our application. For our weather forecasting application, we can prompt the user to enter the city they are interested in receiving weather forecasts.

Code Implementation for Weather Forecasting:

To implement the code for weather forecasting, we need to start by importing the requests module. This module provides an easy way to receive the weather data.

Once we have imported the module, we can create a function called Gen_report that generates the weather report.

Using wttr for Weather Forecasting:

Now that we have created our function, we need to use the wttr command-line tool to get the weather forecast for a particular city.

The wttr tool provides a way to request weather data from command line. We can use the requests module to communicate with the wttr tool and get weather updates.

Handling Errors with the Try-Except Block:

In coding, errors are inevitable. Therefore, it would be best to use the try-except block to handle errors that may arise.

For instance, if the user enters an incorrect city name or the system fails to communicate with the wttr tool, an error can occur. Using the try-except block, we can handle such errors to ensure that the user receives a smooth experience when using our application.


To sum up, creating a weather forecasting application using Python is no easy task, but with the right tools and knowledge, it is achievable. In this article, we have discussed the importance of weather forecasting, how to install the request library, and the user interface for our application.

We have also explored code implementation using the wttr command-line tool and error handling using the try-except block. By following these steps, you can create an application that can forecast the weather accurately, making your daily activities more manageable and productive.

3) Complete code implementation for weather forecasting in Python:

Now that we have gone through the importance of weather forecasting, installed the request library, created a user interface, and implemented the code for weather forecasting, let’s bring everything together to create the complete code.

Here’s how to generate weather reports for an input city using Python:


import requests



url = f”{city}?format=j1″

res = requests.get(url)

if res.status_code == 200:

data = res.json()

current_condition = data[‘current_condition’][0]

weather_desc = current_condition[‘weatherDesc’][0][‘value’]

temp_c = int(current_condition[‘temp_C’])

feels_like_c = int(current_condition[‘FeelsLikeC’])

humidity = int(current_condition[‘humidity’])

wind_speed_mph = int(current_condition[‘windspeedMiles’])

wind_speed_kmh = int(current_condition[‘windspeedKmph’])

weather_report = f”””

The weather in {city} is {weather_desc}. The temperature is {temp_c}C and feels like {feels_like_c}C.

The humidity is at {humidity}%. The wind speed is {wind_speed_mph}mph or {wind_speed_kmh}km/h.




print(“Error fetching weather report.”)


The `gen_report` function is called with an argument of `city`. It builds the URL and makes an HTTP GET request to `` to retrieve the weather report.

If the request is successful, it extracts the necessary data from the response object and formats the report. Otherwise, it outputs an error message.

To use this function, we can add a prompt to ask the user to input their city of interest. Then we can call the `gen_report` function with the city name as argument:


city = input(“Enter the city name to get the weather report: “)



Output Screenshots:

Let’s take a look at some sample output screenshots from running the code for different cities:

![Weather Forecast for London](

![Weather Forecast for New York](

![Weather Forecast for Tokyo](

As we can see from these screenshots, our code is generating accurate weather reports for different cities.

4) Conclusion and Potential Extensions:

Creating a weather forecasting application does not have to be difficult.

With Python, we can build applications that can generate weather reports accurately. We started by understanding the importance of weather forecasting, moving on to the installation of the request library, creating a user interface, implementing the code for weather forecasting, and finally, the complete code implementation.

With this basic application up and running, there is potential for experimentation and further development.

One extension could be to create a graphical user interface using tools such as PyQt or Tkinter.

This would make it easier for users who are not familiar with command-line interface to interact with the application. Another extension could be to scrape web pages for weather data instead of using the wttr tool.

This would allow for more control over data ingestion and presentation.

Furthermore, one could take this project to the next level by creating their own weather-forecasting website.

With just a few basic python libraries and some web development know-how, it is possible to build a weather-forecasting website that can forecast the weather accurately.

In conclusion, with the ease of implementing weather forecasting using Python, and the potential for experimentation and website creation, there is no better time to start than now.

In this article, we have explored how to create a weather forecasting application using Python. We discussed the importance of weather prediction and the ease of implementing a weather forecasting application.

We covered the installation of the request library, the user interface, code implementation, and creating a complete code for weather forecasting. We also highlighted potential extensions, such as building a graphical user interface and creating a weather-forecasting website.

With Python, we can build applications that forecast weather accurately and help manage our daily activities. Weather forecasting is essential in tourism, transportation, and farming.

The takeaways from this article are that with the right tools, knowledge, and creativity, we can build not just a weather-forecasting application but also extend it to more significant projects such as website creation.
