Python Top Libraries You Need to Create ML Model

Creating a Model of Machine Learning in Python, you need two libraries. One is 'NUMPY' and the other one is 'PANDA'.


For this project, we are using Python Libraries to Create a Model.
What Are Key Libraries You Need I have explained in the below steps. You need Two.
NUMPY - It has the capabilities of CalculationsPANDA - It has the capabilities of Data processing. To Build a model of Machine learning you need the right kind of data. So, to use data for your project, the Data should be refined. Else, it will not give accurate results. Data AnalysisData Pre-processing How to Import Libraries in Pythonimportnumpy as np # linear algebra
importpandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)

How to Check NUMPY/Pandas installed After '.' you need to give double underscore on both the sides of version. 
How Many Types of Data You Need You need two types of data. One is data to build a model and the other one is data you need to test the model. Data to build…

SQL built-in functions useful to read quickly

You can find there are four different types of functions in SQL. All these functions are built-in functions. You no need to create these functions, and these come with your SQL.

sql built-in functions with examples

I am discussing today about SQL functions List.

SQL functions

  1. DATE-TIME functions
  2. Numeric functions
  3. Char functions
  4. Null-related functions

1. DATE-TIME functions

These functions useful to get DATE and Time. Also you can covert DATE and TIME to Char. These are TO_CHAR, CURRENT_DATE and CURRENT_TIME

2. Numeric Functions

These functions you can use for numeric calculations. Those are TRUNC, SIGN, ROUND, ABS

3. Char Functions

To handle string related tasks you can use CHAR functions. The CHAR functions are like SUBSTR, CONCAT, LENGTH.

4. NULL related functions

To handle null values you can use different functions. Those are COALESCE, NVL, NULLIF

This post covered all your answers for SQL functions list, SQL built-in functions in Oracle, and SQL functions in any DBMS.
