# How to do numerical operations in Python using Numpy?

This recipe helps you do numerical operations in Python using Numpy

## Recipe Objective

Numerical operation are very essential part of data preprocessing.

So this is the recipe on how we can do numerical operations in Python using Numpy.

We have imported numpy which is needed. ``` import numpy as np ```

## Step 2 - Creating a Matrix

We have created an numpy array. ``` sales = np.array([4352, 233, 3245, 256, 2394]) print(sales) ```

## Step 3 - Numerical analysis

We have done calculated mean, minimum, maximum and sum of the values in array. ``` print(sales.mean()) print(sales.sum()) print(sales.min()) print(sales.max()) ``` So the output comes as

```[4352  233 3245  256 2394]

2096.0

10480

233

4352
```

#### Relevant Projects

##### Time Series Forecasting with LSTM Neural Network Python
Deep Learning Project- Learn to apply deep learning paradigm to forecast univariate time series data.

##### Loan Eligibility Prediction in Python using H2O.ai
In this loan prediction project you will build predictive models in Python using H2O.ai to predict if an applicant is able to repay the loan or not.

##### Learn to prepare data for your next machine learning project
Text data requires special preparation before you can start using it for any machine learning project.In this ML project, you will learn about applying Machine Learning models to create classifiers and learn how to make sense of textual data.

##### Convolutional RCCn's for extracting the text out of images
CRNNs combine both convolutional and recurrent architectures and is widely used in text detection and optical character recognition (OCR). In this project, we are going to use a CRNN architecture to detect text in sample images. The data we are going to use is TRSynth100k from Kaggle. Given an image containing some text, the goal here is to correctly identify the text using the CRNN architecture. We are going to train the model end-to-end from scratch.

##### German Credit Dataset Analysis to Classify Loan Applications
In this data science project, you will work with German credit dataset using classification techniques like Decision Tree, Neural Networks etc to classify loan applications using R.

##### Loan Eligibility Prediction using Gradient Boosting Classifier
This data science in python project predicts if a loan should be given to an applicant or not. We predict if the customer is eligible for loan based on several factors like credit score and past history.

##### Creating your own embeddings using Glove and Word2vec
We all at some point in time wished to create our own language as a child! But what if certain words always cooccur with another in a corpus? Thus you can make your own model which will understand which word goes with which one, which words are often coming together etc. This all can be done by building a custom embeddings model which we create in this project

##### Inventory Demand Forecasting using Machine Learning in R
In this machine learning project, you will develop a machine learning model to accurately forecast inventory demand based on historical sales data.

##### Classification of T shirt images to see if they have text on them
Want to search images of clothes which have text on them? Then this project talks through how we can classify an image whether it has text on it or not. For this we use state of the model called as inception and try and deepdive into how it works on our dataset

##### Build a Face Recognition System in Python using FaceNet
In this deep learning project, you will build your own face recognition system in Python using OpenCV and FaceNet by extracting features from an image of a person's face.
