# Predict a Value using Pandas Dataframe

Solution Kit

In Python, **predict() function** enables us to predict the labels of the data values based on the trained mode, and the **syntax** for predict function is the **model.predict(data).** It accepts only a single argument, usually the data to be tested.

Predict function passes the input vector through the model and returns the output tensor for each data point, and since the last layer in your model is a single Dense neuron, then the output for any data point is a single value. We did not specify an activation for the last layer, and it will default to linear activation in Python. The predicted value is nothing but simulations that consider the estimation uncertainty and the fundamental uncertainty. For example, for any given of x, we go straight in the line and then move horizontally to the left of the data to discover the value of Y. The anticipated value of Y is called the predicted value of Y, and it is denoted Y'. **Dependent variables** are those we want to predict, whereas independent variables are variables we use to predict the other variable's value.

**Libraries used to predict a value using Pandas DataFrame:**

**Pandas:**It is an open-source library that provides high-performance data manipulation in Python.**Matplotlib:**a comprehensive library for creating animated, interactive visuals and static.**NumPy:**It is a python library used for work with arrays.

Here is an example of how to predict a value using Pandas DataFrame:

### Code

In this solution we're using Pandas, Matplotlib and NumPy libraries.

### Instructions

__Follow the steps carefully to get the output easily.__

- Install pandas on your IDE(Any of your favorite IDE).
- Copy the snippet using the '
**copy'**and paste it in your IDE. - Add required dependencies and import them in Python file.
- Run the file to generate the output.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.

*I found this code snippet by searching for **'how to predict a value using pandas dataframe' **in kandi. You can try any such use case!*

### Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

- The solution is created in PyCharm 2021.3.
- The solution is tested on Python 3.9.7.
- Pandas version-v1.5.2.
- numpy version-v1.24.0.
- Matplotlib version-v3.6.2.

Using this solution, we are able to predict a value using pandas dataframe with simple steps. This process also facilities an easy way to use, **hassle-free** method to create a hands-on working version of code which would help us to predict a value using pandas dataframe.
