Python top two ideas you need to Compare Strings

Image
By
In Python, you can compare two strings how you would do on numbers. Python is stricter on string comparison. It identifies any small differences in strings. So Python is case sensitive while comparing it checks for identical ones.
Python follow-suite other languages. It compares strings for exact equals. Else, treat them as different strings.

Python String Comparison 

  • Extra spaces
  • Uppercase or Lowercase

#1 Example

>>> a = "Virginia"
>>> b = "virginia"
>>> a == b False 

The strings a and b are looking similar. But there is case sensitive difference. Python checks for extra white spaces as well as Upper or Lowe case letters.

#2 Example

>>> greet1 = "Hello "
>>> greet2 = "Hello"
>>> greet1  == greet2 False

The greet1 has space at the end whereas greet2 does not. Python looks at whitespace when comparing strings, so the two aren’t considered equal.

SQL queries how to use built-in functions correctly

By
In this post I am giving top examples on SQL functions. About built-in functions, I have covered in my previous post.
List of examples:DATE-TIME functionsNumeric functionsChar functionsNull-related functions1. DATE/TIME functions SELECT p_code, launch_dt, CURRENT_DATE FROM product; CURRENT_DATE returns current date.
SELECT p_code, TO_CHAR(launch_dt, 'DD MONTH YYYY') reformatted_dt FROM product; TO_CHAR function returns DATE in CHAR format.
2. Numeric functions SELECT p_code, price, (price - 20), ABS(price - 20.00) FROM product; ABS - function returns absolute value
SELECT p_code, price, ROUND (price, 1) FROM product;
ROUND function - Round to 1 digit.
SELECT p_code, price, SIGN(price - 15) FROM product;
SIGN function - It returns sign; either + or -
SELECT p_code, price, TRUNC(price, 1) FROM product;
TRUNC function - Truncates to a certain number of decimal places.

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

Robotic process automation is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tool. So, learn anyone tool to start your career in automation.
To get a job in this line, I found in my research that some programming skills and Hand-on training on any one of the tools is required. Also, try to know the differences between popular RPA tools.
Skills Companies Looking in Automation Engineers All big companies looking for candidates having experience in Automation anywhere, Blue Prism and UIPath. It is not possible to learn all tools. Learn anyone tool and do practice well.

Ok.

You may ask a question about how to do it. Join in good training institute and learn one tool.  Take online classes to learn faster.

Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.

BluePrism Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. The technology is scalable, secure, resilient, and flexible and is supported by a comprehensive methodology, operational framework and provided as packaged software.The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ens…
