You can also manage data collection with the knowledge of ETL pipelines in Python or Query Language.

### 4. Data Cleaning

This is where you have to spend most of your time as a data scientist. Data cleaning is about gaining data, which is fit for doing work and analysis, missing values, removing unwanted values, outliers, categorical values and wrongly submitted records from the Raw form of data. Data cleaning is crucial because the real-world data is messy and attaining it with the help of a wide array of Python libraries (Numpy & Pandas) is crucial for the data scientist career.

### 5. A Detailed Knowledge of Deep Learning

Machine learning is the core skill needed to become a data scientist. It is useful for building different predictive models, classification models and more. The best part is that companies optimize their plan according to the predictions. On the other hand, deep learning is the advanced version of machine learning that uses a neural network. This is a framework that combines different machine learning algorithms to solve different tasks to train data. The different neural networks include recurrent neural networks (RNN) and convolutional neural networks (CNN).

### 6. Learning of ML Model

Deployment is the process of making the process of the machine learning model available to the end-users. You can achieve this with the integration of the model with a lot of existing production environments. Therefore you can implement the practical use of the ML model for different business solutions.
